ISELIN, N.J., May 08, 2018 (GLOBE NEWSWIRE) -- TDK Corporation today announced that it has extended its HVC series of high-voltage contactors by introducing the new HVC300 and HVC500 types with current capabilities of 300 A and 500 A, respectively. The new contactors can switch high voltages of up to 900 V DC, while types for 1200 V DC are available on request. The gas-filled switching chamber of HVC series contactors ensures that arcs are safely and quickly extinguished when the current is switched off.

Due to the extremely fast switching capability of the HVC high-voltage contactors the duration of arcs is especially short, thus enabling reliable operations over the entire lifetime of the contactor. The new types have the same compact design as the HVC200 for 200 A with the same dimensions of 89 mm x 44 mm x 93.5 mm (l x w x h). Like the HVC 200, the new high-voltage contactors are available with coils for operating voltages of 12 V or 24 V. In addition, the series includes types with an output for switching status detection.

The HVC series is ideal 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.
