The
200ADM provides commissioning and maintenance
engineers with a flexible system for testing
protective systems. It has an easy to understand
panel layout and a simple user interface. The status
of every function can be seen at a glance, and there
are no complex menus to navigate.
The unit has a range of outputs allowing injection
of currents as low as 1mA and as high as 200A.
Voltages- up to 240V are available on the main
outputs, allowing high impedance current relays and
voltage relays to be tested. Four true RMS metering
ranges are provided, allowing the full scale of the
meter and trip level to be set independently of the
selected output-. Industry standard safety
connectors are used on all inputs and outputs for
convenience, reliability and safety.
The 200ADM is comprehensively protected by
overcurrent, duty cycle and thermal trips, and keeps
the user fully informed of any trip condition.
The back-lit display on the 200ADM is bright and
clear with a wide viewing angle. The results of a
test can be seen here as they appear on the display.
An auxiliary metering input is provided and can
measure AC and DC voltage, current, frequency, and
the phase between the main current output and an
external voltage or current. A stabilised DC supply
is provided to power the relay under test, along
with an independently variable AC output.
The timing system is very flexible without
compro-mising ease of use, allowing trip times,
reset times and reclose times to be quickly measured
to a high degree of accuracy.
