Over Current Protection (OCP)
In the event of an over current due to a short circuit in the load, the output is turned OFF and switching is ceased to
protect the load.
The OCP current can be set from 1% to 110% of the rated current.

that can flow rated current.
. Turn the POWER switch ON with the Output ON/OFF Toggle mode (FUNC.51) set to "0".
. Set the Output Current settings lower than OCP level.
. Turn OUTPUT to ON.
. Gradually increase the Output Current with the CURRENT dial. Verify
that the output turns OFF once the OCP set
current has been reached and that the error code "E005" appears in the Number Display (voltage) and the Number
Display (current) becomes the "OCP" display.
. Hold the OVP and OCP keys simultaneously for more tha
n 1 second to cancel the alarm. Return the CC set value to
its original value.
● Press the CURRENT 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).
● If the number of parallel devices (total power) is changed,
the OCP set value is set again to the maximum value.
