4.5.2 Set Over-Current Protection (OCP)

Users can enable the OCP function and set the protection limit Level and pro-

tection delay time Delay. When the current (i.e., the Meter value) is greater than

this protection limit and the delay time is exceeded, the power supply will enter

the OCP state.

Possible Cause

Many reasons can cause OCP, the details are as follows:

• The set protection limit Level is lower than the current Meter value.

• The external (AC input) inputs a higher current.

• The power supply outputs a high current due to a fault.

How to Set

The operation steps to set OCP are as follows.
