Three Phase Constant Voltage Compensators

Three Phase Volt Drop Compensators / Boosters in ratings from 6 to 200 kVA

Our Three Phase ranges of Constant Voltage Compensators eliminate inherent volt drops over long cable runs, ensuring a constant output voltage - even in situations where the load varies with demand. Available as either Indoor IP20 / NEMA 1 or Outdoor IP54 / NEMA 3 style solutions, the 380 to 415V (H Series) and 200 to 220V (LY Series) Three Phase Volt Drop Compensators ranges are detailed in the TABs below.
