TDK Corporation (TSE:6762) presents HVC27 (B88269X*), its new generation of high-voltage contactors that can safely and reliably switch off continuous DC currents of 300 A to 500 A and operating DC voltages of up to 1000 V 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 as well as to power motor drive systems and do regenerative braking (recuperation).

The necessary change to environmentally friendly use of energy leads to the high demand for high-voltage and high-current DC applications.
TDK offers the High-Voltage Contactors (HVC) series which meet the requirements for High-Voltage DC emergency disconnection applications up to 600 A in electric cars, trucks, busses and DC fast chargers.
HVC series features excellent extinguishing characteristics in combination with a bipolar design for charging and discharging.

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.
