The T&R 200A-3PH mk2 is a flexible 3 phase current injection system capable of supplying currents of up to 200A 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 to supply voltages of up to 5Vac.

An independently isolated output is provided for each phase, allowing a wide range of output configurations to be selected. A single phase isolated auxiliary AC output of 110Vac is also available.

The 200A-3PH Mk2 is equally at home testing solid state or electro-mechanical relays, and has a rating suitable for testing thermal trips. The unit has independent true RMS digital metering for each output, with independently selectable ranges. The outputs are isolated and independently variable, and allow the injection of currents up to 200A. The outputs are protected by electronic over-current trips and fuses.

The 200A-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 200A-3PH mk2 to a live system. Always check that the power to the device under test is off and the circuit is isolated before making any connections.
