The VarPlus detuned reactor are designed to protect the capacitor by preventing the amplification of the harmonics present in the system. Capacitors and Reactors are configured in Series resonant circuit. Tuned so that the series resonant frequency is below the lowest harmonic frequency present in the system. This reactor is rated for 50 kVar output power with 2.7/135 Hz tuning order at 400V AC at 50 Hz. Relative impedance, 14 %. This component meet the standards IEC 60068. This component require a forced convection, a fan need to be added. The case dimensions are 270mm in height, 260mm in width and 200mm in depth. For a product weight of 33 kg.
