This system consists of a control unit which is compatible with one of two loading units (both of which are sold separately). Please note that you will require one of the loading units to use this tester.

Working with high currents? The T & R PCU2 mk5 outputs maximum current to 5000A (5kA), giving users complete control over the injection of high currents as part of commissioning and maintenance.

Optimised for use in difficult conditions, both the control unit and the optional loading units for this product are encased in tough, durable steel cases complete with castor wheels and protective lifting handles for easier transportation. The systems are designed to take up as little space as possible, ensuring they can be placed as close as possible to the object under test to minimise power requirements and ensure that available current is at its maximum level.

The PCU2 is made with flexibility in mind; by using the loading unit and the control unit, users can easily configure different current injection levels. For example, a control unit and a LU5000 loading unit could be used to inject current of 5000A up to 5 minutes, 8000A for  seconds or 10000A for 1 seconds. Other loading units and settings are available depending upon the configuration of the unit (please see the attached user manual for more information).

This product is ideal for a wide range of primary current injection applications such as testing CT ratio, circuit breakers and under/over current relays.
