TDK extends HVC offerings with addition of new compact, high-voltage contactors

TDK Corporation (TSE: 6762) has extended its range of bipolar DC high-voltage contactors to include the new HVC43 (B88269X3**0C011) series. These products complete the existing range by offering continuous currents from 150 A DC to 250 A DC and operating voltages of up to 1000 V DC. The contactors are available in 12 V or 24 V coils with a power consumption of 6 W.

The new HVC43 series types provide compact dimensions of 78 x 40.4 x 74.5 mm (L x W x H), weigh 300 g, and are 30 per cent smaller and lighter than the HVC200, HVC300, and HVC500 types, designed for voltages of up to 1200 V DC and continuous currents of 500 A DC.

The contactors include a hermetically sealed gas-filled ceramic arc chamber, offering outstanding extinguishing properties, and are specially designed to quickly shut down high direct currents of lithium-ion batteries in vehicles, charging stations, or energy storage systems.
