Over Voltage Protection (OVP)
I
n the event of an over voltage due to circuit failure of the power supply, improper use, load opens in constant current
mode, etc. the output is turned OFF and switching is ceased to protect the load.
The OVP voltage can be set from 1% to 110% of the rated voltage.
Setting/Canceling Over Voltage Protection
Setting Over Voltage Protection Level

Set the output to OFF with the OUTPUT key.

Press the OVP/OCP key to display the current OVP set value in the top Number Display (voltage).

Change the set v
alue by turning the VOLTAGE dial while pressing down the OVP/OCP key.
(Turn the dial right to raise or left to lower the set value.)

Release the OVP/OCP key to confirm set values and to return to measurement display mode.

Verifying Over Voltage Protection Operation
After settings are complete, please follow the procedures below to test verify operation.

Disconnect the load from the power supply.

Turn the POWER switch ON with the Output ON/OFF Toggle mode (FUNC.51)
set to "0".

Set the Output Voltage settings lower than OVP level.

Turn OUTPUT to ON.

Gradually increase the Output Voltage with the VOLTAGE dial. Verify that the output turns OFF once the OVP
set voltage has been reached and that the error code "E004" appears in the Number Display (voltage) and
"OUP" appears in the Number Display (current).

Hold down the ALARM RESET key for more than 1 second to cancel the alarm. Return the CV set value to its
original value.
● Press the VOLTAGE dial to display the current number
position. The selected number will be brightened. Press
to change position.
If all 4 places are brightened, numbers will change from
the lowest place.
● Press the OVP/OCP key to display the OVP set value in
the Number Display (voltage) and the OCP set value in
the Number Display (current).
