OVP
This parameter is used to set over voltage protection value. Once the output voltage
exceeds the OVP set value, N39200 will immediately shut off the output and protect
the DUT. Meanwhile, alarm OVP will be displayed on the screen.
OCP
This parameter is used to set over current protection value. Once the output current
exceeds the OCP set value, N39200 will immediately shut off the output and protect
the DUT. Meanwhile, alarm OCP will be displayed on the screen.
OPP
This parameter is used to set over power protection value. Once the output power
exceeds the OPP set value, N39200 will immediately shut off the output and protect
the DUT. Meanwhile, alarm OPP will be displayed on the screen.
CV/CC priority
In general, operation mode of power supply depends on the output voltage setting,
output current limit setting and load impedance.
In the case of high impedance or open circuit, the current flowing through the power
supply is very low or there is no current. The power supply is in CV (constant voltage)
mode.
In the case of low impedance or short circuit, high current flows through the power
supply. The power supply is in CC (constant current) mode.
N39200 series allows users to select CV priority or CC priority.
