Setting the overvoltage protection
The OVP Set control turns overvoltage protection (OVP) on or off. If overvoltage protection is turned
on and the instrument senses a voltage level above the threshold set for over-voltage control, the
instrument will turn off the output and clamp the voltage on the output to below one volt.
To set the overvoltage protection:
1. Press Shift and Menu (1) to access the configuration menus.
2. Use the arrow keys, numeric keypad, or navigation wheel to select >Protect.
3. Press Enter.
4. Use the up or down arrow keys to select >OVP Set.
5. Press Enter.
6. Select On.
7. Press Enter.
8. Enter the desired OVP value with the numeric keypad, arrow keys, or navigation wheel .
9. Press Enter
The lower display shows OVP when the overvoltage protection feature is activated. The OVP
indicator will flash on and off when the overvoltage protection feature detects an overvoltage
condition.
The default value for the Max Volt Set parameter is On.
Resetting the power supply after an overvoltage trip
To reset the power supply after an overvoltage trip:
1. Determine and remove the source of the overvoltage. Overvoltage may be caused by setting the
voltage limit too high, external voltage sources, or equipment failure.
2. Press the Output On/Off key to clear the OVP status. This will put the power supply output in the
off state.
