Page 7: Function Introduction
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; ... - Page 8 2. Series and Parallel Settings 2.1 Series Settings: Press CH1 button for 3 seconds to enter series mode, the “SER” symbol will be on. CH1+ is the main positive output of series and CH2- is the slave negative output. The series voltage and current settings can only be adjusted in CH1, and the CH2 settings will follow that of CH1.
- Page 9 3. Constant Voltage / Constant Current In constant voltage mode, the output current is lower than set value, the channel indicator will be green (CV), and the voltage keeps as set value. If the output current reaches the set value, the device will switch to the constant current mode.
- Page 10 6. 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.

8. 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 the mobile phone and so on. The USB_Device interface on the rear panel comes with communication function for software programing and upgrade, and output control of power supply by upper computer. - Page 12 10. SET VIEW Introduction When the power output is on, the voltage and current displayed on the LCD are the real-time sampling output values. Press SET VIEW button (backlight on) to view the voltage and current set values. Press SET VIEW button again (backlight off), the LCD redisplays the real-time sampling output voltage and current.
