- OCP (Over Current Protection) Short Circuit Protection:
- Short press the "OCP" button to enable or disable the OCP alarm function.
- Press and hold the "OCP" button for 3 seconds to enter the OCP setting state. Use the current adjustment knob to set the OCP current value.
- When OCP is enabled, an alarm will sound, and the machine will stop outputting if an external load short circuit or over current occurs, protecting the load.
- To clear the OCP alarm, short press the OCP button.
- OVP (survoltage Protection) Function:
- Short press the "OVP" button to enable or disable the OVP function.
- Press and hold the "OVP" button for 3 seconds to enter the OVP setting state. Use the voltage adjustment knob to set the OVP voltage valeur.
- When OVP is enabled, if the load voltage exceeds the set OVP voltage, the machine will stop outputting and issue an alarm, protecting external loads.
- Short press the OVP button to clear the OVP alarm.
- OUTPUT On/Off: Short press the "OUTPUT" button to toggle the power supply output on or off. This allows for safe connection/disconnection of loads without powering down the unit.
