Ocp Operation - ITech IT8500plus Series User Manual

VON LATCH MODE
In Latch mode,as before,the load will turn on only when the voltage exceed
VON setting,but once on,it will now stay on,even if the voltage drops to zero.

3.12 OCP Operation

OCP test process: After input voltage reaches VON point,the DC load start to
draw a current from the source after a delay time.The current value will
increase by a certain step size at regular intervals.Simultaneously,the DC load
will judge whether the input voltage is lower than OCP voltage you've set.If it
is,then the present current value will be compared to see if it is in the current
range you've set,in this range,the OCP test will Pass or fail.On the contrary,the
DC load will continue to increase drawing current and compare the voltage.
To start an OCP test,press [ Shift ]+ [
Press [ Shift ]+ [ CC ] (OCP) to enter OCP operation.

Set the power on mode to be OCP test mode:
