    Function Introduction 1. Voltage / Current Setting and Output Voltage setting: Press CH1 button, the cursor will flash on the CH1 voltage position,  press the voltage knob to move the cursor and rotate the knob to adjust the voltage value; Current setting: Press CH1 again, the cursor will flash on the CH1 current position, press ...
  • Page 7 The series output connection is as follows: Series positive output Series negative output Parallel Settings: Press CH2 button for 3s to enter parallel mode, the “PARA” symbol will be on. CH1+ is  the main positive output of parallel and CH1- is the slave negative output. The parallel voltage and current settings can only be adjusted in CH1, and the CH2 settings will follow that of CH1.
  • Page 8 Channel 1 indicator Channel 2 indicator Channel 3 indicator OVP (overvoltage protection), OCP (overcurrent protection) Setting and Enabling Long press OVP button (>3s) to enter OVP threshold setting, press CH1 or CH2 to select  the channel, then rotate the voltage knob to set the OVP limit, long press OVP button again to exit the OVP setting.
  • Page 9 CH3 Output The CH3 has 4 sets of fixed outputs which are 1.8V/2.5V/3.3V/5.0V/3A, which can be fine adjusted by OUTPUT button. By pressing the CH3 button, the output voltage can be switched between 1.8V/2.5V/3.3V/5.0V and the corresponding indicator will be on. Double press the CH3 button, the cursor will flash on CH3 voltage and can be fine adjusted.
  • Page 10 USB Interfaces The USB Host interface on the front panel is not for communication but for an independent CH4 channel, which comes with fixed output of 5V/2A, can be used to charge USB devices such as mobile phones etc. USB charging interface The USB Device interface on the rear panel comes with communication function for software programing and upgrade, and output control of power supply by connected computer.
  • Page 11 Buzzer On and Off Press the sounder button (backlight on), the buzzer will be on; long press the sounder button for 3s, the buzzer will turn off. With the shutdown memory function, the last saved settings can be restored when the device is started up next time.
