SAFETY BRIEF:
This manual contains important safety instructions that must be followed in the operation and storage environment of the RSPS series.To ensure your personal safety, and ensures that this product works in the best environment, please read this manual carefully before using .

Product Advantage:

【Dual channel power supply】Independent dualchannel constant voltage and constant current automatic conversion function. The two adjustable channels can be used independently or automatically in series and parallel, and have masterslave automatic tracking and adjustment functions.
【Three output modes】The three output modes of the dualchannel DC regulated power supply are independent, series and parallel modes.
【Series connection mode】 Double voltage output in series mode can form positive and negative power outputs, which is especially suitable for occasions that require symmetrical and adjustable bipolar power supplies. Example 120V 3A up to 240V 3A
【Parallel connection mode】 Double current expansion output in parallel mode. Example 30V 10A up to 30V 20A.
【One key switch series parallel】 Say goodbye to complex wiring and setting, by pressing "SER/PAR" arbitrarily switch series and parallel, super convenient !
【Encoder knob】: This product button uses encoder knob, you can directly set the voltage and current value rather than adjust, very convenient and accurate.
【Multiprotection functions】Equipped with grounding wire, overheat protection, overvoltage protection, overcurrent protection and short circuit protection to ensure safety; after testing, it can maintain full load operation for more than 24 hours. The builtin smart cooling fan can reduce noise and effectively extend product life.
【Excellent quality】Using 100% pure copper terminals, with good conductivity. Highquality cables are used internally to ensure the safe operation of the machine. Using highquality hardware makes our products more precise.

OPERATION INSTRUCTION
There are two types of power output modes: constant voltageoutput (CV) and constant current output (CC).The output modeis determined by the voltage and current values set by the userand the load connected by the user.The output voltage or current value of the power supply won'T exceed the voltage andcurrent values set by the user. ln constant voltage mode, theoutput voltage value is equal to the userset voltage value. Inconstant current mode, the output current value is equal to theuserset current value.

Attention：
ln actual CV operation, if the load resistance decreases and theoutput current increases to the set current value, the power supplywill automatically switch to cC mode. When the load resistancevalue continues to decrease, the current will remain at the currentset value.The voltage is proportionally reduced.At this time, increase the load resistance or increase the current set value torestore the CV output state.

CONNECT THE LOAD
1. Rotate the terminal knob by turning it counterclockwise
2. Insert the load terminal
3. Turn the terminal knob clockwise
4. Banana plug can be directly inserted into the terminal hole

Attention：
lmproper connection may result in damage to the powersupply and the load connected to the power supply. Whenconnecting the battery load, do not reverse the polarity ofthe "+" and"-" as this may damage the power supply.

CONSTANT VOLTAGE/ CONSTANT CURRENTCHARACTERISTICS
The working characteristics of this series of power supplies areconstant voltage/constant current automatic conversion type,which can automatically change between constant voltage andconstant current states with load changes.The intersectionbetween constant voltage and constant current mode is calledconversion point.For example, if the load causes the power supply to operate in A constant voltage mode, A constant voltageis output.As the load increases, the output voltage will remainconstant and the output current will increase. When the currentvalue reaches the set current limit value, the power supply willautomatically switch to constant current mode.The outputcurrent remains stable and the output voltage decreases proportionally as the load increases further.The conversion ofconstant voltage and constant current is indicated by the LED onthe front panel.

CV indicator light is on during constant voltage, cC indicator ison when constant current.

HIGH VOLTAGE!
DANGER!
For effective safety protection, it is only necessary toreplace the fuse of A specific specification.Before replacing the fuse,the power must be turned off and thepower cord must be unplugged from the power outlet.

PRODUCT MAINTANCE
