Power-Factor-Correction Capacitors Withstand Harsh Surroundings

EPCOS has developed an especially rugged new series of power factor correction (PFC) capacitors. They are based on MKV technology and are distinguished by their high temperature tolerance and long operating life. The capacitors of the B25836B*A305 series are available for voltages between 400 and 800 V at 50/60 Hz. Their reactive power ranges between 5 and 30 kvar. Inrush current can be up to 500 times the rated current, and the surge current capability is three times the rated current. As stipulated by temperature class -40/D, they have a life expectancy of 300,000 hours. According to IEC 60831-1+/2, 50,000 switching operations per year are permissible when used in a detuned circuit, and 20,000 without reactors. EPCOS AG, Munich, Germany. +49 89 636 09.
