Main Output
The units have three independently controlled outputs, one for
each phase. The output is switched on and off by illuminated
pushbuttons, and the current is set using the three control knobs
on the front panel. All ranges are continuously variable from
zero.
Range Continuous 5 minutes 1 minute
5V 50A 100A 200A
The above intermittent on times must be followed by an off time
of 15 minutes, and are based on an ambient temperature of 25°C.
Auxiliary AC Outputs
A switched, isolated auxiliary 240V 50mA AC supply is available
to power auxiliary control circuits. The output is protected by a
fuse.
Metering
The output on the 200A-3PH/ED is metered by a digital true
RMS system with a 3.5 digit LED display. The range for each
channel is independently selected for each channel by a switch
on the front panel.
Range Resolution Trip Current Accuracy
10A 0.01A 11.5A ±0.6% rdg+6d

An electronic current trip is automatically set to 115% of full scale
of the selected metering range to protect the device under test.

Timing System
The timing system on the 200A-3PH/ED is very flexible, allowing
a wide range of protective devices to be timed.
Range 0-999.999s
Resolution 1ms
Accuracy 0.01% rdg +1d (all except current operated mode)

The contact circuit has an open circuit voltage of 24Vdc and a
short circuit current of 300mA. The contacts may be connected
to volt-free contacts or contacts connected to a DC voltage
system (220Vdc maximum).
The following functions are provided:

The output is automatically switched off at the end of the test to
safeguard the relay under test.
Protection and Safety
The 200A-3PH/ED is protected by electronic over current trips on
the outputs, fuses on the contact input, the mains input and
regulators.
The auxiliary AC output is fuse protected. An earth terminal is
provided for connection to a local earth.
The unit is designed to comply with BSEN61010, and is CE
marked.
Optional Delta-Star Supply Transformer
The optional delta-star supply transformer allows operation from
115V, 230V, 400V, and 440V 3 wire (delta) supplies. The input
voltage is selected by a switch on the unit. An auxiliary single
phase output is also provided to supply power to a DVS3 voltage
source.
