Larger Three Phase Constant Voltage Compensators

Three Phase Volt Drop Compensators / Boosters in ratings from 250 to 1500 kVA

Our Larger Three Phase ranges of Constant Voltage Compensators specifically configured for the needs of larger site applications where the maintenance of a fault tolerant input voltage window for mission critical applications is essential and the general supply infrastructure may already incorporate some of the protection features commonly integrated as standard in our CVC & OCVC-3P-SM or TM ranges. 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.
