Over Voltage Protection (OVP) Calibration

Over Voltage Protection (OVP) Calibration

We recommend that you perform OVP calibration every six months. Connecting a

digital voltmeter as in “Voltage Calibration Setup” is optional.

1. Disconnect all loads from the power supply.

2. Ensure that jumper J95 on the interface PCB is CLOSED to enable remote OVP

calibration (Jumper J95 is closed at the factory). See Figure 2.3, RS-232

Interface PCB continued., p. 18 for the location on the PCB of jumper J95.

3. Activate calibration mode by sending command CMODE ON or CMODE 1 to

the power supply.

4. Send the command OVCAL to the power supply. The ADDR LED will light

during OVP calibration. Calibration is complete when the ADDR LED turns off.

This may take a few minutes.

5. Use the OVSET,OVSET?, and VSET commands to trip the OVP level,

confirming that the calibration was successful. When you trip the OVP level, the

red OVP LED will light and the voltage will drop to zero. Send the command

RST to clear the OVP condition. Refer to the OVP program accuracy

specification in Section 1.

6. Turn off calibration mode by sending the command CMODEOFF or CMODE 0

to the power supply.
