High-voltage contactors with 200 A continuous current target e-mobility and photovoltaics
TDK has launched a bipolar hermetically sealed high-voltage contactor for switching high DC voltages up to 450 V and 200 A continuous currents.

High-voltage contactors with a high continuous current capability are used in applictions such as e-mobility for the fast disconnection of the battery from the drive, as well as in DC charging stations. The hermetically sealed switching chamber ensures that the arcs that occur when disconnecting the DC load at these voltages and current are safely extinguished.

The HVC200A measures 89 mm x 44 mm x 93.5 mm (l x w x h) and is available in drive versions for 12 V (B88269X1000C) or 24 V (B88269X1010C). Both versions have a power of 6 W at the rated voltage. As an option, the new contactors can be equipped with a circuit for detecting the switching status.

Other applications include photovoltaic systems and uninterruptible power supplies (UPS). Versions with 12 V and 24 V drives for continuous currents of between 100 A and 500 A at maximum permissible operating voltages of 900 V are currently in development.
