TDK-EPC has extended its range of power factor correction (PFC) capacitors: the EPCOS PhaseCap Compact series now also comprises types for voltages of 415 V a.c., 440 V a.c., 480 V a.c. and 525 V a.c. As an alternative to capacitors with dimensions of 136 x 200 mm (D x H), types with dimensions of only 116 x 224 mm or 116 x 248 mm are now also available, depending on the reactive power that must be compensated.
The series now covers a voltage range from 230 to 525 V a.c. and a capacitance range of between 3 x 27 μF and 3 x 251 μF (50 Hz). Depending on the type, they can compensate reactive powers ranging from 5 to 33 kVAR. Thanks to their special construction, the capacitors can withstand an inrush current of up to 300 times the rated current. The components are lead-free and their self-healing design means that individual dielectric breakdowns do not destroy the capacitor. An integrated over-pressure disconnector ensures additional safety. The capacitors are designed for a continuous operating temperature of 65°C (casing) and a service life of up to 180 000 hours.
