3-5. Programming Over Current Protection(OCP)
If output current is higher than OCP Level, this function shut off the output current to protect
load from power supply. It is OCP Level Set-up & ON,OFF set-up below :
OCP Level Value below can be different.
▌Power Switch ON
Check "**OUTPUT OFF**" Mode is displayed after input Power ON.
▌Press PROTECT Key to Set-up the Level

Note
If actual output current is higher than OCP Level, OCP TRIPPED will be displayed and all the
output voltage and currents will be shut-off. To print voltage and current again,
remove load and follow below sequence to clear the trip.
Trip can be occurred
First It can happen when OCP Level value is accidentally tripped.
Therefore, raise Level value to solve the problem.
Second There can be a trip when users used load which cause counter electromotive
Second
There can be a trip when users used load which cause counter electromotive
force such as Coil & Motors. Diagram 3-2 above shows how to prevent it.
