4.2.8 OVP Mode

The OVP (overvoltage protection) test function can capture the peak point of the input
voltage and the entire fall process after protection. When the voltage drops to the set
trigger voltage, the load will record the time from the peak point to the trigger point. This
recorded time is the over-voltage protection time of the tested power supply.
Parameter setting in OVP mode:
Trigger voltage
If users want to perform OVP test, they can press More in the menu to select the OVP test
mode, set the voltage of the trigger point, and then press the ON button to start loading.
The overvoltage protection function of the power supply is triggered by increasing the
output voltage of the power supply under test. After the load captures the peak and falling
