PowerLogic PFC filter circuit chokes are designed to protect the capacitor by preventing the increase of harmonics present in the system. Capacitors and chokes are configured in series resonant circuit. Tuned so that the series resonant frequency is below the lowest harmonic frequency present in the system. This choke is designed for 100 kvar output power with detuning factor of 14% (2.7/135 Hz) at 400 VAC and 50 Hz. Relative impedance, 14%. This component complies with IEC 60068. This component requires additional convection, that is, a fan must be added. The dimensions of the enclosure are 350 mm in height, 350 mm in width and 220 mm in depth. For a product weight of 55 kg.
