Product Specifications

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.

Analogue Metering: 200A-3PH/E
The output on the 200A-3PH/E is metered by a digital true RMS system with analogue meters. The range for each channel is selected by a switch on the front panel.

Range	Accuracy
50A	1% of full scale
100A	1% of full scale
200A	1% of full scale

Digital Metering: 200A-3PH/ED
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% of reading +6 digits
20A	0.01A	23A	±0.6% of reading +6 digits
100A	0.1A	115A	±0.6% of reading +6 digits
200A	0.1A	230A	±0.6% of reading +6 digits

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

Supply Requirements
400V+14%-6% 50/60Hz 3-phase 4 wire 3300VA max
A delta-star transformer is available as an optional accessory for operation from a 3 wire supply.

Temperature Range
Storage Temperature: -20°C to 60°C
Operating Temperature: 0°C to 45°C

Dimensions
200A-3PH/E: 315mm x 550mm x 300mm
200A-3PH/ED: 315mm x 550mm x 300mm

Weight
200A-3PH/E: 35kg
200A-3PH/ED: 35kg

Timing System
The timing system on the 200A-3PH/E/ED is very flexible, allowing a wide range of protective devices to be timed.

Range	0 to 999.999s
Resolution	1ms
Accuracy	0.01% of reading +1 digit	(all except current operated mode)
	0.01% of reading +3 digits	(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:

Mode	Timer Start	Timer Stop
Normally Open	Press 'ON'	Contact closes
Normally Closed	Press 'ON'	Contact opens
Current Operated	Current >20% of range	Current<20% of range
OFF	Timer inoperative	Timer inoperative

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 200A-3PH/E is protected by fuses on the contact input, the mains input and regulators.

The auxiliary AC output is fuse protected on both units. An earth terminal is provided for connection to a local
earth.

The unit is designed to comply with BSEN61010, and is CE marked.

Accessories Supplied with Unit
Operating manual, mains lead, spare fuse set.

Optional Accessories
200AL/3PH Output lead set.

Optional Lead Set specifications
The 200AL/3PH lead set includes the following items:

6ea. 5meter 25mm2 200A leads terminated in M10 fork crimps.
1ea. 5meter 2 core auxiliary lead terminated in 4mm plugs.
1ea. 5meter 2 core auxiliary lead terminated bare ends.

The lead set is supplied in a reinforced plastic wallet.
