High-voltage Contactors Handle up to 900Vdc and 500A

TDK Corporation has extended its HVC series of high-voltage contactors with the new HVC300 and HVC500 types with current capabilities of 300A and 500A, respectively. The new contactors can switch high voltages of up to 900Vdc, while types for 1200Vdc are available on request.

Their hermetically-sealed gas-filled switching chamber ensures that arcs are safely and quickly extinguished when the current is switched off. Thanks to the extremely fast switching capability of the HVC high-voltage contactors the duration of arcs is especially short enabling reliable operations over the entire lifetime of the contactor.

The new types have the same compact design as the HVC200 for 200A with the same dimensions of 89 mm x 44 mm x 93.5 mm (l x w x h). Like the HVC200, the new high-voltage contactors are available with coils for operating voltages of 12V or 24V.

In addition, the series includes types with an output for switching status detection. The HVC series is especially suitable for use in battery management systems and dc charging stations in e-mobility applications.

Further applications include dc traction systems, photovoltaic, energy storage systems, and uninterruptable power supplies (UPS). These applications require fast and reliable disconnecting from the dc source.
