EPCOS PFC capacitors are extremely popular in low voltage (up to 800V) power factor correction and harmonic suppression applications. EPCOS offers PhaseCap and WindCap are manufactured with the latest dry MKK technology. They have long useful life, high pulse current withstand capability and comply with IEC831 and UL/cUL requirements.
The PhseCap Compact developed by EPCOS is a new series of PFC capacitors distinguished by its long operating life and large pulse strength. The inrush current can reach up to 300 times and the overcurrent up to twice the rated value. The capacitors are based on the proven MKK technology featuring concentric three-phase capacitor windings. They reach an operating life of up to 130,000 hours to temperature class -40/D and up to 180,000 hours to temperature class -40/C.
Like all PFC capacitors from EPCOS, the new series is also self-healing thanks to the MKK technology and a polypropylene dielectric. In addition, the capacitors have an overpressure disconnector that separates them from the power grid in the event of a fault.
PFC capacitors are part of the comprehensive EPCOS product range for power factor correction, which also comprises controllers, thyristor modules, capacitor contactors, reactors and discharge resistors.
EPCOS AC capacitors are widely used in magnetic type ballast in lighting application to provide on source, power factor correction.
