Wiring diagram

Notes:
1. The potentiometer adjustment mode must use high precision multi circle potentiometer with resistance ≥ 10K Ω
2. The external control voltage regulation mode must use DC control voltage with high stability and low ripple
3. GND, SGND and HGND have already been connected internally and connected to the power supply shell
4. R/S Connects to TTL high and low levels
Control-output Curve Relationship

Main Precautions
- To ensure the technical indexes of high-voltage power supply and reduce mutual interference, it is recommended to use independent voltage power supply.
- When connecting with the external circuit, please ensure the accuracy of the connection and ensure there is no loose connection or short circuit, to avoid damaging the power supply and users’ equipment.
- Keep a certain insulation distance near the power output end to avoid high voltage arcing or ignition with surrounding components.
