New HVC Series High-Voltage Contactors Can Switch Voltages up to 900 V

Press Release Summary:

TDK’s HVC Series High-Voltage Contactors now include HVC300 and HVC500 types with current capabilities of 300 A and 500 A respectively. Units come with gas-filled switching chamber that allows safe and quick extinguishing when the current is switched off. These contactors are suitable for DC traction systems, photovoltaic, energy storage systems, and uninterruptable power supplies. Units are offered in 89 mm x 44 mm x 93.5 mm (l x w x h) hermetically sealed package.

Original Press Release:

Portfolio of High-Voltage Contactors Extended for High Current Capabilities up to 500 A

TDK Corporation has extended its HVC series of high-voltage contactors with 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.

Their 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, 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 HVC200, 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 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.

Main applications

  • Battery management systems and DC charging stations for e-mobility applications
  • Photovoltaic and energy storage systems
  • Uninterruptable power supplies

Main features and benefits

  • High current capability of up to 500 A
  • Hermetically sealed and high-speed arc extinguishing
  • Optional detection of switching status
