Theory of Operation
The theory of operation chapter describes the basic principles of
operation, protection modes and important considerations that
must be taken into account before use.
Operating Area Description
Background
The PSU power supplies are regulated DC
power supplies with a high voltage and current
output. These operate in CC or CV mode
within a wide operating range limited only by
the voltage or current output.
The operating area of each power supply is
determined by the rated output power as well
as the voltage and current rating.
Below is a comparison of the operating areas of
each power supply.
