The PCU1E MK3 is ideally suited to commissioning and maintenance testing where high currents up to 3000A are required. The control unit contains all control and metering circuitry, and is linked to the Loading Unit by control and metering cables. The control unit is capable of injection of currents up to 100A. The combination of the PCU1E and a suitable loading unit is ideal for all low power Primary Current Injection tasks up to 3000A, including testing under and over relays, circuit breakers and CT Radio testing. There are two loading units available the T&R LU2000A and the T&R LU3000A and a full range of outlet leads are available to connect the PCU1E and loading units.
