3-4. Programming Over Voltage Protection(OVP)
Function that protects by shutting off output voltage when the voltage is higher than OVP Level.
Read OVP Level Set-up Below.
Disable OVP function in Factory Mode.
OVP 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

will be displayed. It shut-off output voltage and current to prevent the sources.
To output voltage and current again, remove the load and follow the sequence below to
Clear the Trip. The Trip might occurred by :
First It can happen when OVP 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
force such as Coil & Motors. Diagram below shows how to prevent it.
