Product Specifications
 

PCU-LT/PCU1-SP Control Unit Specification
Loading Unit Current Metering The AC output current is metered by a true RMS memory ammeter (acquisition time 200ms) with a liquid crystal display. The current metering has 3 ranges corresponding to 10%, 50% and 100% of the maximum rating of the loading unit. In addition, a 200% metering range is enabled in pulse mode.

Timing System
The PCU1 systems have a flexible timing system with two contact inputs and 5 operating modes. Each contact circuit automatically selects for N/O or N/C contacts, and the status of each contact input is shown by an LED. The timing channels may also be triggered by a dc voltage between 24 and 240V.

Pulse mode (note: 2)
Applies current to the load for a maximum of the specified time. If contact set 1 changes state or the current
drops below 20% of the metering range during the pulse time, the timer is stopped. The maximum output current is increased in pulse mode (limited only by circuit impedances). The maximum obtainable current is set by the impedance of the test object and output leads.

Current operated mode (note:1)
Current operated mode is used to time devices with no auxiliary contacts (many types of circuit breakers). The timer is started when the current exceeds 20% of the selected metering range (e.g. 100A on the NLU5000 500A range). The timer stops when the current falls (i.e. the breaker opens).
 
Secondary Injection Output (PCU1-SP only)
The secondary current injection output on the unit has two taps, allowing the injection of currents up to 100A.

Protection and Safety
The PCU1 series and loading units are CE marked and are designed to meet the requirements of BS EN61010. The system is protected by electronic trips on the outputs, circuit breakers on the mains input, control unit output and secondary injection output (PCU1-SP only). The unit also has a duty cycle trip on the loading unit output and the loading unit has comprehensive thermal protection.

Optional Loading Unit Specifications
Two loading units are available to provide a range of output currents suitable for different primary injection tasks. Each loading unit has three output taps allowing current injection into a wide range of loads of differing impedances. Optional output lead sets are also available.
