5.5.1 Current RMS Protection

The user can set the over-current protection point, delay time and protection
type for the Current RMS protection function. The function is mainly used to
protect the DUT connected during test to prevent it from damage due to over-
current. The OCP (rms) function is always enabled.

Limit: If the output current reaches the RMS current protection point, the
protection will be activated. The power supply output current is controlled
within the current limiting value. The power supply will output in current limit
mode.
Output Disable: When the output current reaches the over-current
protection point and the period is greater than the set protection delay time,
the over-current protection (rms) will turn off the output.
