Main Output
The main output on the unit has four taps, allowing the selection of
output voltages up to 240V and output currents up to 100A.
*Off time of 15 minutes. On times based on an ambient temperature of 25°C.
**6 second intermittent ratings available with 230V supply.
I Limit Mode
The main output has a current limit mode that gives very fine control
of output currents up to 10A. It also allows fine current control into
very low impedance loads such as digital relays.
Auxiliary AC and DC Outputs
A switched, isolated auxiliary DC supply with current limit protection
is available to power the relay under test, and a 110Vac auxiliary
output is available for tests.
DC stabilised output 24V, 48V, 60V 1.0A
110V, 220V 0.23A
Fixed AC output 110Vac 300mA
Metering
The output is metered by a digital true RMS system with a single
cycle capture memory ammeter—whenever the timer stops and the
output is switched off, the reading is held on the display. A current
trip is set to 110% of full scale of the selected metering range.
Supply Requirements

Each contact circuit will auto-select for normally open or normally
closed contacts. A DC voltage of 24—240VDC may also be used to
trigger either timer channel. Contact state is shown by an LED. The
output automatically switches off at the end of the test to safeguard
the relay under test.
Pulse mode is used for setting the current level in devices sensitive
to heating. Current is injected for 200ms.
RS232 and T&R Link
An RS232 port is provided to allow connection to a PC or a printer.
The T&R Link output allows a T&R DVS3 mk2 voltage source to
phase lock to the 100ADM mk4 current..
Protection and Safety
The unit is designed to comply with BSEN61010 and is CE marked.
An earth terminal is provided for connection to a local earth for
testing in sub-station environments.
