current supply unit is ideal for a) performance and turn-ratio tests
of current transformers, b) primary tests of protective relays,
c) current tests on low- and high-voltage circuit breakers and d)
commissioning tests that require variable currents.
The CSU600AT™ provides a more comprehensive solution. It has
a built-in timer and an analog ammeter that provide rough current
settings quickly and easily. As a result, connection time has been
