The OPP test function creates an automatic test to
test the OPP of power supply products.
This test will test to see when the over power
protection of a power supply is tripped and return
the measurements for the voltage and current
when the over power protection was tripped. The
PEL-3000(H) also has a user-defined cutoff setting
in the event that the power supply OPP fails.
The diagram below shows an example of the OPP
Test Automation function:
The test watt increases from a starting value (Start
W) to an end value (End W). The watt increases in
steps (set by Step_W) with a set step time (set by
Step_T) until the power supply’s OPP is tripped or
the End W watt level is reached.
