Product Description
Gigavac G8SF SPDT HV Relay
Gigavac G8SF SPDT High Voltage Relay - 15kV / 30A
The Gigavac G8SF is a high-performance Single Pole Double Throw (SPDT) high-voltage relay, engineered for precision power management and superior dielectric isolation. Capable of handling peak voltages up to 15kV and a robust continuous carry current of 30 Amps, this vacuum-sealed relay ensures exceptionally low (0.025 Ohms) and stable contact resistance. With its rapid response times (15ms operate / 9ms release) and a mechanical life of 1 million cycles, the G8SF series is a premier choice for high-voltage power supplies, medical imaging equipment, and advanced RF communication systems where safety and long-term switching reliability are paramount.
