Resetting the OVP Circuit

To reset the OVP circuit after it activates:

1. Reduce the power supply’s output voltage setting to below the OVP

set point.

2. Press the STANDBY switch IN. The red S/D LED on the front panel

turns on. The OVP LED turns off.

3. Press the STANDBY switch again to return power to the load and

resume normal operation.

1. Reduce the power supply’s output voltage setting to below the OVP

set point.

2. Turn the power supply OFF using the AC power switch, wait until the

front panel displays go out, then turn the power supply back ON

again.
