- Multi-function digital timing system
- Digital true RMS memory ammeter
- Solid state switching
- 200A, 2000A and 5000A loading units
- Three range outputs on loading units
- Rugged, compact design
- Optional trolley mounting of system
- Secondary injection up to 100A
- Auxiliary metering input
- Direct reading CT ratio and polarity
The PCU1-SP Mk2 Primary Current Injection Test System, a medium powered instrument, enables output currents of up to 5000A (11.5kVA for 40 seconds). It comprises a separate control unit that houses all metering and control functions, along with a loading unit (such as the NLU200, NLU2000, or NLU5000) responsible for delivering the high current output.
The PCU1-SP Mk2 Primary Current Injection Test System is a medium-powered instrument that can deliver output currents of up to 5000A (11.5kVA for 40 seconds). It consists of a control unit and a loading unit (NLU200, NLU2000, or NLU5000) that delivers the high current output.
This system is perfect for primary current injection, stability testing, and circuit breaker testing, and also offers direct-reading CT ratio and polarity tests. It comes with a 100A secondary injection output and 3 loading units that provide maximum output currents of 2000A or 5000A. Each loading unit has three output taps to accommodate a wide range of load impedances.
The control unit has an 11.5kVA rating and can handle 2-second overload capabilities of up to 23kVA using pulse mode. All metering functions are digital and accurate, with a memory feature that retains the current reading even when the output trips or is switched off. The system uses a reliable solid-state device to control the current, which automatically shuts off when the device under test experiences a trip event.
The PCU1-SP Mk2 also has a high-accuracy timing system that allows for precise timing tests with a resolution of 1ms. It offers automatic selection for normally open or normally closed contacts, with the status of the contacts displayed on the front panel. It provides various timing modes for testing under and over current devices, re-closers, under and over voltage devices, current trips, and circuit breakers.
To ensure optimal performance and compatibility, a comprehensive range of high current output leads is available in different lengths. Output leads designed for use with the NLU2000 are available in lengths ranging from 1.5m to 5m, while leads suitable for the NLU5000 come in 1.5m and 3m variants.
