OVP Test

OVP test is used to test the protection voltage level and response time of the of OVP module of the power supply.  JT63 series electronic load provides OVP test function. Users should set the trigger voltage level slightly higher than steady-state voltage level showed after OVP protection. Then simulate the power supply’s voltage rising process, the electronic load can capture and display the protection trigger voltage level and response time of the OVP module of the power supply. Users can adjust the adjustable potentiometer of the measured power supply or disconnect the feedback loop of the power supply or other ways to force the voltage of the measured power supply to rise higher than OVP voltage level protection value.

Start testing in the pre-load conditions, the detection power can normally start, as well as voltage and current destructive overshoot process
