Vacuum Relay (HV Relay)

Vacuum Relays are widely used in airborne, mobile and marine communications equipment. Typical applications include antenna coupling, tap changing on radio frequency (RF) coils, transmit / receive switching to an antenna, switching in pulse-forming networks and heavy duty power supplies. Our relays are noted for fast operating speeds and the ability to withstand high voltages and carry heavy currents, while maintaining low and stable contact resistance. Vacuum relays are available in SPST normally open (N/O) and normally closed (N/C) models, as well as SPDT configurations. Latching relays are available in some models.

Greegoo's high-voltage relay and vacuum capacitor are user-friendly and can fully replace those from Kilovac, Jennings, Crydom/Gigavac and Comet. If you cannot find a suitable model, please send us their part numbers, and we will recommend an appropriate one for you.
