• OCP (overcurrent protection)
The overcurrent protection function protects a load from unexpect-

activated when the current exceeds
a preset current (OCP trip point).
Selectable range: 10 % to 110 % of the rated output current.
If the OCP function is activated when CONFIG is set to OUTPUT
OFF, the voltage display shows "OCP."
For details, see "3.2.3 Setting the OCP (Overcurrent Protection) Trip
Point".

rais
es abnormally.
This function protects the unit from the following conditions.
• When the unit is used in an environment exceeding the opera-

If the OHP function is activated, the
vo
ltage display shows "OHP".
If the condition that caused the OHP to be activated is not corrected,
