Value Set in 1°steps IF Set AND the temperature reaches, or exceeds, the set value: ● The output will immediately turn OFF. ● The “ON/OFF” button will turn off it’s illumination, ○ or react per the setting of ‘External LED’. ● Charge Status, on the display, will be set to "CHARGE: T°-OFF", indicating that the charging cycle was halted due to temperature. Notes:

Disabled by setting to 0.

This setting is only applicable using the (Green) Battery Charging Binding post.

Should be set to a higher value than the ambient temperature for proper operation.

‘CutOff Temp’ setting is similar to the ‘OTP (EXT)’ setting, in that both serve the same purpose of setting an upper temperature limit.

23

However, ‘OTP (EXT)’ is a global feature,not limited to battery charging. final safety measure, not specifically for battery charging. IF ‘CutOff Temp’ AND ‘OTP (EXT)’ are Enabled: The value of ‘OTP (EXT)’ should be higher than the ‘CutOff Temp’ to ensure proper operation. CutOff time ➥Battery Charger OFF NOT monitoring total time of charge while battery charging. Settable Range: 00h 01m - 99h 59m. IF Set, Battery charging cycle will halt once the set time is achieved. Note: This setting is only applicable using the (Green) Battery Charging Binding post. Custom Colors ➥Colors ` ON Custom Colors are used, where set in the ‘Colors Group’ menu options. OFF Default Colors are used. For information on how to set up the Custom Colors see: ‘Colors Group’ Detailed Explanation. CV—>CC Beep ➥Buzzer ON Buzzer sounds once when switching from CV to CC mode. OFF Buzzer does NOT sound when switching between modes. Date ➥Date and Time Rotate the ‘Encoder’ knob to the desired value. Use “◄” or “►” to switch selected fields. Date Format

IF the External LED Modification has NOT been made… This value has NO effect. Good practice - Set to OFF Hint ➥Memory OFF Memory Hint will not be displayed. Value Time, in seconds, that the Memory Hint will be displayed. When enabled, Pressing a memory location number (“M1” - “M9”) will display the values stored at that location for the time set. Pressing the same button again (double press) will apply the settings. I-Off Lockout ➥Battery Charger OFF NOT monitoring Cutoff Current. Settable Range: 00m - 60m. IF Set, Sets the delay before activating the "Cutoff Current" function. Note: This setting is only applicable using the (Green) Battery Charging Binding post.

27 Instant Out ➥Memory When recalling settings from a Memory Location ON Output will turn ON automatically when memory Selected/Recalled. OFF Output Maintains existing ON/OFF status. Graph Window Accessed via Quick Setting Menu (“SHIFT” + “▼”) Settable Range: 00h 01m - 23h 59m This is the time of the entire width of the graphing window, as indicated in the image. Note: Values will be averaged as needed to fit the desired time. See ‘Graph Display - Detailed Explanation’ for a detailed explanation of the Graphing Mode. Green Output Quick Setting Menu (“SHIFT” + “▼”) If ENABLED then the GREEN terminal will work as an output over relay. NOTE! In this mode, the battery detection is disabled, so charger mode will not work. Temperature/MEM/SHIFT are displayed in GREEN (no space for a separate icon). I-SET (Set Current, in Amps) Can Only be Enabled by Panel button “I-SET” Value of the Current Setpoint, in Amps, for when the unit is in CC Mode. Rotate “Encoder” knob to desired value. Use “◄” or “►” to switch selected multiplier. OR Enter the desired value using the Keypad.

28 A long press on the button opens a menu that allows the settings of an upper and lower limit to the value. These limits are not retained between reboots. ISET > OCP+200 ➥Power Settings OFF Prevent current from exceeding the OCP setting. ON-CODE Allow current to exceed OCP setting - See conditions, below. With 'ISET > OCP+200' OFF, The unit will NOT allow the output current to go above the protection value, as described in the ‘OCP’ Setting details. Except, The time from output current reaching the OCP value and the PS turning OFF (Protection Mode) could be delayed by up to 600ms; rather than immediately as a more advanced/expensive PS_s would do. With 'ISET > OCP+200' ON, The unit WILL allow the output Current to go to whatever value is selected (I-SET), regardless of the ‘OCP’ value. However, since the value is above the ‘OCP’ value, Protection Mode will still be activated, after the delay, IF the output current has not fallen back below the OCP value. This setup is for load devices with high in-rush current that lasts less than the delay time: Output current can go over the OCP value for short bursts, to a MAXIMUM of ‘I-SET’, and for less than the response delay, up to 600ms. The response delay is due to a lack of a hardware-implemented ‘over current’ protection. This is unavoidable with the RD60xx and cannot be corrected in Firmware. IF the output current reaches ‘I-SET’ the (Hardware Controlled) fast change to CC mode would lower the Voltage to maintain the I-Set maximum, until after the response delay. IF the inrush lasts less than the Delay time and then falls below the OCP value, the unit will continue to operate like a normal CV Mode only Power Supply. However, IF the current draw climbs back above the OCP value: ● The RD60xx will NOT go into CC Mode. ● The RD60xx WILL go into Protection Mode after the response delay Special Notes:

This option is for ADVANCED USERS ONLY.

Improper use could result in Equipment or Personal Damage.

29

Ensure you understand how this option works before use.

To enable this option, the ‘ON-CODE’ value MUST be set to 11235. (Hint to remember the code: Fibonacci Sequence) Any other value will result in the option being set to OFF.

On Testing, the Delay is typically around 250ms, but has been measured up to 600ms. Key Beep ➥Buzzer ON Buzzer sounds once when any button(s) is pressed. OFF Buzzer does NOT sound when button(s) pressed. LOCK Can Only be Enabled by Panel buttons “SHIFT” + “●” When enabled, physical buttons and encoder knob have no effect. Press Lock button combination again to disable. Language ➥Interface Selectable Options: English Chinese Deutsch Français Pyсский Layout ➥Interface Sets Default screen on Power-up LastState Layout used last on previous session 0 Default Layout - from original, manufacturer Firmware. 1 Customisable Layout, as selected on the ‘Layout 1’ Group settings 2 “Layout 2”, which is like Battery Charging below, but: if OVP, OCP, OPP is triggered, this parameter will be displayed instead of INPUT. 3 Battery Charging 4 Graph Display Layout

30 A simplified graphical preview of the selected layout will be shown below the setting. Leading Zeros ➥Appearance Change the appearance & behavior of digits and decimal points on screen. Three options are available: Default: Blank: FloatPoint: Max V-Set ➥Power Settings Settable Range: OFF, 1.00V - 61.00V.

31 Limits V-SET Max Power ➥Power Settings Settable Range: Up to Maximum Power Rating of the unit. RD6006: 360W RD6012: 720W RD6018: 1080W Limits output power to set value.

• Protects the primary power supply if not capable of providing full power of RD60xx. Manufacturer recommended setting: No higher than 95% of the rated power for the Primary Power Supply. Example: IF using a 800W primary supply on an RD6018, Set the ‘Max Power’ value no higher than: 800W x 0.95 = 760W Min Input ➥Power Settings Settable Range: OFF, 6.00V - 72.00V. Below 6V = OFF Sets the minimum accepted input voltage. This can be useful if you power the unit via batteries, to avoid over-discharging them. IF Set, and the input voltage falls below the specified value, then ● the output will be disabled (and will be blocked) ● at the bottom in the status icon "INPUT UVP" will be displayed ● a corresponding message will be displayed on the screen:

32 Mute ➥Buzzer ON Buzzer does NOT sound, regardless of other settings. OFF Buzzer functions as set by the other Buzzer Group settings.

33 OCP (Over Current Protection) Can only be enabled by Panel buttons (“SHIFT” + “I-SET”) IF the Output Current exceeds, the set value: ● Unit will enter Protection Mode. ● The output will immediately turn OFF, upon entering Protection Mode. (See Notes: **) ○ (versus the RD60xx unit adjusting output to maintain the ‘I-Set’ value.) ● The “ON/OFF” Button will turn off its illumination, ○ or react per the setting of ‘External LED’. ● The Current measurement value will be changed to the ‘OCP’ display color. ○ See ‘Colors Group’ Detailed Explanation ● The Normal Operating Mode indicator is replaced by a red background white ‘OCP’ Icon. Notes:

Disabled by setting to 0.

When Setting, “SHIFT” button will be illuminated to visually distinguish an ‘OCP’ input from an ‘I-SET’ input.

** OCP is controlled via firmware, not hardware **.

As a result, there could be a delay of up to 600ms between the Current reaching the set value and the RD60xx going into Protection Mode.

Should be set to a higher value than ‘I-Set’ for proper operation.

See ‘ISET > OCP+200’ for an Advanced Option that allows this situation.

Setting OCP lower than I-SET is typically not a good idea.

It was done for the example image, below, to deliberately trigger OCP. Example Screen Image of OCP Protection activated

34 OPP (Over Power Protection) Can Only be Enabled by Panel buttons (“SHIFT” + “MEM”) Sets the value for the maximum power allowable in the current session (volatile) or can be stored in the memory location via the menu. Maximum power is calculated by multiplying the Voltage (V) and the Current (A) outputs. IF the total Output Power exceeds, the set value: ● Unit will enter Protection Mode. ● The output will immediately turn OFF. ● The “ON/OFF” button will turn off its illumination, ○ or react per the setting of ‘External LED’. ● The Power measurement value will be changed to the ‘OPP’ display color. ○ See ‘Colors Group’ Detailed Explanation ● The Normal Operating Mode indicator is replaced by a red background white ‘OPP’ icon. Notes:

Disabled by setting to 0.

This setting (OPP) does NOT override the ‘MAX Power’ setting.

The PC Software and Smartphone App from Ruideng DO NOT recognize this error. IF the RD60xx enters Protection mode due to OPP: Connected (Riden) Software, using any interface (USB, UART), will report an OCP Error. ORP (Over Resistance Protection) ➥Power Settings or Quick Setting Menu (“SHIFT” + “▼”) ON Unit monitors for Over Resistance using ‘ORP delay’ and ‘ORP set’ settings. OFF Unit does NOT monitor Over Resistance events. IF Set AND tripped: ● Unit will enter Protection Mode. ● The output will immediately turn OFF. ● The “ON/OFF” Button will turn off it’s illumination, ○ or react per the setting of ‘External LED’. ● The Normal Operating Mode indicator is replaced by a red background white ‘ORP’ Icon. ORP is similar to Inrush Current Limiting (ICL) (on other Power supplies), ORP trips out the RD60xx, while ICL would place an upper limit on the current it will source.

35 Notes: The PC Software and Smartphone App from Ruideng DO NOT recognize this Error. IF the RD60xx enters Protection mode due to ORP: Connected (Riden) Software, using any interface (USB, UART), will report an OCP Error. An example of ORP being tripped. In this example: ORP turned ON. ‘ORP set’ value: 6.00 Ω. ‘ORP delay’ Set to: Auto. The RD60xx was connected to a 5 Ω, 20 W resistor. When the RD60xx calculated its effective load resistance (output Voltage divided by output Current measurements) as 5 Ω, the ORP was triggered (as this is less than the 6 Ω from ‘ORP set’). Example Note: It took 1.8 seconds to trip after the ON/OFF button enabled the output. (With the resistor pre-connected) It took 1.2 seconds to trip when the resistor was connected while the output was already enabled. ORP delay ➥Power Settings or Quick Setting Menu (“SHIFT” + “▼”) Auto Waits until the Voltage has stopped rising for at least 500ms. Value Set in 0.1s (seconds) steps, up to a maximum of 10 seconds. IF ‘ORP’ ON: Time the load at the resistance across the Battery (Green) Binding Post and Negative (Black) binding post can be in a fault state, as defined by ‘ORP Set’, before the ORP puts the RD60xx into Protection Mode. To demonstrate the ‘ORP delay’ setting: (Using a RD6018) ● ‘ORP delay’ was set to its maximum value of 10 seconds. ● ‘ORP’ was set to 1.12 Ω. ● ‘Graph Window’ was set to 1 minute (its minimum).

36 ● An attached electronic load was set to 1 Ω. ● The electronic load was turned on before the RD6018 output was turned ON. ● Graphing was started about 15 seconds before the RD6018 output was turned ON. This graph shows: ● RD6018 output was 9 Volts and 9 Amps, in CV mode, for approximately 10 seconds. ● After that time, the ORP tripped out. This shows the ‘ORP delay’ setting waits approximately 10 seconds (the set value) before determining whether ‘ORP’ should trip. (In this example it does trip because the effective load resistance is 1 Ω, which is less than the ORP set value of 1.12 Ω.) Measured on an oscilloscope (not shown), with the ‘ORP delay’ at its minimum value of 0.1 seconds, and the 5 Ω resistor setup used in the ‘ORP’ example: ORP tripped at 0.14 seconds from the ON button being pressed. (Measured from when the output voltage started to rise above zero.) With the RD6018 already ON, it took about 0.7 seconds to trip after the 5 Ω resistor was connected. ORP set ➥Power Settings or Quick Setting Menu (“SHIFT” + “▼”) Value Set in 0.01Ω steps, starting from 0.01Ω See ‘ORP’ Setting for details on use. OTP (ext) (Over Temperature Protection - External Sensor) ➥Power Settings OFF Unit does not monitor for Over Temperature events on the external probe. Value Set in 1°steps IF Set AND the temperature reaches, or exceeds, the set value: ● Unit will enter Protection Mode. ● The output will immediately turn OFF.

37 ● The “ON/OFF” Button will turn off its illumination, ○ or react per the setting of ‘External LED’. ● The Normal Operating Mode Indicator is replaced by a red background white ‘OTP’ Icon. Notes:

Disabled by setting to 0.

Should be set to a higher value than the ambient temperature for proper operation.

This setting does NOT affect the RD60xx cooling fan. (Which will turn on automatically when the internal sensor reaches 40°C.)

There is a pre-set, 80°C, non-changeable OTP for the internal sensor.

The external temperature probe CAN be used in conjunction with this setting to monitor the Primary Power Supply temperature for overheating, if the user wishes to mount the sensor as such.

The ‘OTP (EXT)’ setting is semi-independent from the ‘CutOff Temp.’ setting used for battery charging.

‘OTP (EXT)’ will trigger Protection Mode during all modes of operation.

‘CutOff Temp.’ only triggers Protection Mode during charging operations.

IF ‘CutOff Temp’ is enabled: This value, ‘OTP (EXT)’, should be set to a higher value than the ‘CutOff Temp’ to ensure proper operation during charging cycles. OVP (Over Voltage Protection) Can only be enabled by Panel buttons (“SHIFT” + “V-SET”) IF the Voltage reaches, or exceeds, the set value: ● Unit will enter Protection Mode. ● The output will immediately turn OFF. ○ (versus the RD60xx unit adjusting its output to maintain the ‘V-Set’ value.) ● The “ON/OFF” Button will turn off its illumination, ○ or react per the setting of ‘External LED’. ● The Voltage measurement value will be changed to the ‘OVP’ display color. ○ See ‘Colors Group’ Detailed Explanation ● The Normal Operating Mode Indicator is replaced by a red background white ‘OVP’ Icon. Notes:

Disabled by setting to 0.

When Setting, “SHIFT” button will be illuminated to visually distinguish an ‘OVP’ input from a ‘V-SET’ input..

Timer Off {CS Menu} Settable Range: 00�00�00 - 99�59�59 (Hours, Minutes, Seconds) IF Set to 00�00�00, ‘Timer Mode’ will not activate. IF Timer Mode active: When value reaches 00�00�00, output will turn OFF. IF ‘Timer On’ is set to 00�00�00, When ‘Timer Off’ expires: Output will turn OFF. The Normal Operating Mode indicator is replaced by a white on red background ‘TIME’ icon. Timer On {CS Menu} Settable Range: 00�00�00 - 99�59�59 (Hours, Minutes, Seconds) IF Timer Mode active: After ‘Timer Off’ expires and the output is turned OFF. ‘Timer On’ will then start counting down. When ‘Timer On’ expires, the output will turn back ON.

48 Timer Reset {CS Menu} IF changing timer values while the output is already ON. ON ‘Timer Mode’ timers will reset/begin after exiting from the menu. OFF ‘Timer Mode’ timers will begin when the output is next turned ON. Notes: Timer begins counting after enabling the RD60xx output. (If the output was already enabled, the timer is already running. ) e.g. If you: Turn on the output, and wait more than 1 min. Enter the menu and set the ‘Timer Reset’ to 1 min Exit from menu (apply setting) Then: Output will immediately turn OFF. (Because 1 min. has already passed since the output was turned ON.) Enabling this option forces the timer to reset when the settings are applied. Timeout ➥V-SET/I-SET/OVP/OCP/OPP OFF: IV Set Timeout is NOT enabled. Settable Range: 00m 01s - 99m 59s Determines if, and for how long, the unit will wait for data entry when setting a value using the “I-SET” or “V-SET” buttons. This applies for setting the Voltage, Current, OVP, OCP, or OPP values. IF Set: ● The timer will reset on any data entry, except “ENTER”. ○ Pressing “ENTER” will apply the current setting. ● The value displayed at the end of the timeout timer will automatically be applied. V-SET (Set Voltage, in Volts) Can Only be Enabled by Panel button “V-SET” Value of the Voltage Setpoint, in Volts, for when the unit is in CV Mode. It also represents an upper limit for Voltage when in CC Mode. Limited by Max V-SET. Rotate “Encoder” Knob to desired value.

49 Use “◄” or “►” to switch selected multiplier (cursor location). OR Enter the desired value using the Keypad. A long press on the button opens a menu that allows the settings of an upper and lower limit to the value. These limits are not retained between reboots. For a lasting upper limit, see Max V-Set. UART Baudrate ➥Communication Selectable Options: 9600 / 19200 / 38400 / 57600 / 115200 / ��� / 1000000 Only applies to the INTERNAL communication ‘UART Interface’. (NOT the front panel USB) IF ‘WIFI’ selected as ‘UART Interface’ setting: Baud Rate is FIXED at 115200, regardless of value selected. UART Interface ➥Communication Each Interface Option has a unique indicator at top of screen when in use. OFF Disable the UART (internal) communication interface WIFI Wi-Fi module (if installed) TTL Simple UART, 3.3V RS485 RS485 Module (if installed) When ‘UART Interface’ changed: The RD60xx MUST be rebooted to apply the modification. Notes: ● ‘Simple UART’ refers to a Full-Duplex, 3-wire, connection (Rx, Tx, and Gnd), without hardware flow control. ○ The communication speed is set using the ‘UART Baudrate’ setting. ● Front Panel Micro-USB interface can be used concurrently with any of these options. Setup via the ‘USB Interface’ setting ● ‘WIFI’ configures the optional WiFi module using AT+ commands. See ‘How to Connect to WiFi’ section for details. ● RS485 uses a simple UART + Enable (En) pin Set while communicating. ○ For interface with the optional, proprietary, RS485 module designed for the RD60xx series.

50 RS485 Interface Mode has NOT Been Tested (UniSoft kept the original Riden firmware code) ● TTL option can be used for any user-defined connection using a Simple UART (No hardware flow control) configuration with 3.3V logic levels. (ie, an additional USB interface, Bluetooth Wireless, Etc) See 'Using the TTL Interface' for more details. ● When enabled an associated Icon is displayed at the top of the screen: WIFI: TTL: RS485: The Icon Color will change to yellow when actively communicating. (See the USB Icon in the ‘USB Interface’ setting for example.) Update Rate ➥Display Regarding measured values, Voltage, Current, Power, Etc. Extra Slow Average value of the last 16 measurements Very Slow Average value of the last 8 measurements Slow Average value of the last 6 measurements Medium Average value of the last 3 measurements High Value of most recent measurement only Options DO NOT affect measurement accuracy. These options are available to smooth measurement Jitter, it is for readability only. USB Interface ➥Communication Selectable Options: OFF / 9600 / 19200 / 38400 / 57600 / 115200 /���/ 1000000 Selects the Baud Rate for use with the Front Panel Micro-USB connector. When enabled, a USB icon will be displayed at the top of the screen: Attention: Baud rate higher than 115200 will not work unless the isolator IC π122U31 is replaced by a faster one, like ISO7221A, ADuM1201ARZ (Both tested). Using baud rate 1000000, reading dump of the screen takes around 2 seconds.

51 UVP (Under Voltage Protection) ➥Power Settings or Quick Setting Menu (“SHIFT” + “▼”) Value Minimum allowable output Voltage, during normal operation IF the Voltage falls below the set value: ● Unit will enter Protection Mode. ● The output will immediately turn OFF. ● The “ON/OFF” button will turn off its illumination, ○ or react per the setting of ‘External LED’. ● The Normal Operating Mode indicator is replaced by a red background with a white ‘UVP’ Icon. Notes:

Disabled by setting to 0.

Protection is not enabled until the Voltage has stopped rising for at least 500ms.

The PC Software and Smartphone App from Ruideng DO NOT Recognize this error. IF the RD60xx enters Protection mode due to UVP: Connected (Riden) Software, using any interface (USB, UART), will report an ‘OVP’ Error. UCP (Under Current Protection) ➥Power Settings or Quick Setting Menu (“SHIFT” + “▼”) Value Minimum allowable output Current, during normal operation IF the Current falls below the set value for more than about a second: ● Unit will enter Protection Mode. ● The output will turn OFF.

52 ● The “ON/OFF” button will turn off its illumination, ○ or react per the setting of ‘External LED’. ● The Normal Operating Mode indicator is replaced by a red background with a white ‘UCP’ Icon. ● Working only in Power Supply mode, no effect in charger mode. Notes:

Disabled by setting to 0.

The same remarks as for UVP probably apply.

Works in conjunction with UCP Trigger UCP Trigger (Under Current Protection Trigger value) ➥Power Settings or Quick Setting Menu (“SHIFT” + “▼”) Value The output Current at which the UCP option gets activated, during normal operation IF the Current goes above the set value, or when OFF: ● Unit will activate the UCP option Notes:
