TDK Company has added the B25674C and the B25674C to the PhaseCap Power Plus sequence of EPCOS PFC capacitors. The B25674C* is gas-impregnated sequence and covers a voltage vary from 230 V AC to 690 V whereas the B25675C* sequence capacitors are impregnated with a biodegradable resin and are able to dealing with voltages from 230 V AC to 1000 V AC. Each the sequence can be utilized at hotspot temperatures as much as 85 °C permissible and have an extended lifetime of as much as 240,000 hours in temperature class -40/D, class IP20 touch-proof terminals, and pre-mounted ceramic-based discharge resistors.
Based on the corporate, the B25674C* sequence which is a gas-impregnated sequence gives compensation scores from 5 kvar to 33.1 kvar whereas protecting a voltage vary from 230 V AC to 690 V AC. The B25675C* sequence capacitors are appropriate for larger voltage ranking than the opposite sequence as it’s rated for voltages from 230 V AC to 1000 V AC, with compensation scores of as much as 60 kvar.
The corporate claims that the capacitors provide as much as 15,000 switching operations per 12 months, double the quantity of earlier sorts. For brief durations, the sequence could be operated at a temperature of 60 °C, with hotspot temperatures of as much as 85 °C permissible. These capacitors are able to dealing with excessive inrush currents as a result of their strong winding design with wave-cutting expertise and might safely deal with inrush currents equal to 500 occasions the rated present. Moreover, the capacitors are self-healing and CE and UL licensed. Additionally they function an inside overpressure disconnector that may disconnect the mains from all three phases within the occasion of an overload. The capacitors function class IP20 touch-proof terminals and have pre-mounted ceramic-based discharge resistors.
These capacitors are extremely dependable with lengthy shelf life making them appropriate for all kinds of purposes such because the capacitor banks, particular person and group compensation, mounted and switched compensation methods in addition to dynamic PFC methods.
