High Level Genset Accessories

The NPU is 3-phase mains protection unit for applications with generators operating in parallel to mains. It provides adjustable voltage, frequency and vector shift protections to preserve both the power supplier and the generators.

The NPU offers convenient display of mains voltage and frequency measured values and fast indication of mains voltage failure via indication LEDs and output relays. Wide range of models featuring various rated voltages, frequencies and supply voltages enables NPU to be used for large scale of applications.

Features:

Included protections:
  • Over voltage
  • Under voltage
  • Voltage asymmetry
  • Over frequency
