Brand T&R Test Equipment

The T&R 50A-3PH mk2 is a flexible 3 phase current injection system capable of supplying currents of up to 50A ac per phase into a variety of loads. The unit is designed for testing devices used for power system protection, but can be used wherever a 3 phase high current AC source is required. The outputs may also be used in voltage mode to supply voltages of up to 18Vac.

The T & R 50A-3PH mk2 requires a 3 phase 4 wire 400V supply (400V version) or a 3 phase 3 wire 220V supply (220V version), but an optional delta-star converter is available, allowing the 400V 50A-3PH mk2 to be operated from 115V, 230V, 400V or 440V three wire supplies.

The 50A-3PH mk2 is designed to be used on ‘dead’ systems (i.e. no externally supplied voltages are present on the test object). Under no conditions connect the 50A-3PH mk2to a live system. Always check that the power to the device under test is off and the circuit is isolated before making any connections.
