TDK presents next-gen high-voltage contactor series for automotive applications

There are three mechanical versions of the UL-certified HVC27 series

TDK announced in a press release on July 11 that its new generation of high-voltage contactors (HVC) can safely and reliably switch off continuous DC currents of 300 A to 500 A and operating DC voltages of up to 1,000V in lithium-ion batteries in 20 ms or less, depending on the type. This is made possible by the gas-filled ceramic arc chamber, which is also used in the other HVC types from TDK. Completely new is the optional Hall-effect sensor for the auxiliary contact. It is used to detect the switching state of the main contacts. The bidirectional design allows only one HVC27 to charge and discharge batteries, power motor drive systems and do regenerative braking (recuperation).
