The unit has a range of outputs allowing injection of currents as low as
a few mA and as high as 100A. Voltages up to 240V are available allowing
high impedance current relays and voltage relays to be tested. Four true
RMS metering ranges are provided, and the full scale of the meter (and
trip level) can be set independently of output tap. Industry standard
safety connectors are used on all inputs and outputs for convenience,
reliability and safety.
A very flexible two channel timing system is provided, allowing trip
times, reset times and reclose times to be quickly measured to a high
degree of accuracy. The timer auto-ranges to measure from 1ms to 99999.9
seconds. The outputs of the 100ADM mk4 are well protected. The main
output is protected by overcurrent, duty cycle and thermal trips. The
auxiliary DC supply is protected by a current limit, and the auxiliary
AC supply is fuse protected.
