The PCU2 from T&R Test Equipment is a primary current injection system designed to be used in conjunction with a T&R Test Equipment loading transformer. Depending on the loading unit used, currents up to 6000A are available for 5 minutes and 12kA for 1 second.

The system consists of separate control and loading units for maximum flexibility. The control unit contains all control and metering circuitry, and is linked to the loading unit by control and metering cables.

The control unit may be used with one of two loading units providing between 5000A or 6000A for 5 minutes or up to 10 or 12kA for short periods. Each loading unit has two outputs
which may be connected in series or parallel for maximum flexibility. For example, the LU6000 may be configured to either give a maximum current of 3000A at 6.6V or 6000A at 3.3V.

The output current is metered by a digital memory ammeter with an LED display. The current reading is continuously updated when the output is energised, and the value held when the
output is de-energised.

The control and loading units are each housed in tough steel cases fitted with castors and protective lifting handles. The loading units have a small plan area to allow them to be
positioned as close as possible to the test object, minimising power requirements and maximising the available current.

The PCU2 mk5 and loading units are CE marked and are designed to meet the requirements of BS EN61010.
