Constant current mode (CC) When the current value exceeds the limit value of the output current, the equipment will work in the CC mode. The CC indicator light on the front panel is on, the output current value is controlled to the set value. Since the limited output power cannot be overloaded, the output voltage can be lower than the set value. When the output current is lower than the set value, the equipment will automatically change to CC mode.

Voltage setting :You can set the voltage by rotating the "VOLTAGE" encoder switch. When entering the voltage setting, the current "digit" being set will blink to indicate. Rotate clockwise to increase the value and counterclockwise to decrease it. Press the encoder switch to move the cursor position. Blinking stops after 5 seconds of completing the voltage setting.
The USB charging function : power supply comes with USB-A and USB-C (TYPE-C) charging ports, which are not affected by voltage and currentregulation and can be charged separately or simultaneously. When used separately, it is in a fast charging state.
Power On: Press the "POWER" button to turn on the power, the screen will display the previous voltage and current values.
OVP overvoltage protection function: Short press the "OVP" button to enable or disable the OVP overvoltage protection function. Press and hold the "OVP" button for 3 seconds to enter the OVP setting state. You can use the voltage adjustment knob to set the voltage value of the OVP. When OVP is enabled, when the load voltage exceeds the set voltage, the machine will stop outputting and issue an alarm, effectively protecting external loads. Short press the OVP button to clear the OVP alarm. 6 OUTPUT On/Off: Short press the "OUTPUT" button to switch the power supply output on or off.
OCP Short Circuit Protection: Short press the "OCP" button to enable or disable the OCP short circuit protection alarm function.
