GLVAC SPST HV Relay
1.5 kV – 70 kV Single Pole Single Throw (SPST) high-voltage relay family — Vacuum, Reed and Gas-Filled technologies
The GLVAC SPST (Single Pole Single Throw) HV Relay family is a comprehensive collection designed for short-duration high-voltage interruption and low-level signal switching. 24 models offer working voltage from 1.5 kV to 70 kV, continuous current from 2A to 65A, and a choice between vacuum, reed, and gas-filled (hydrogen/argon-filled) insulation technologies.
Vacuum-insulated models (GL series: GL41A/B, GL43A/B, GL45C, GL47A/B, GL81A/B, GL22) provide high-voltage interruption performance, fast response time (10 ms operate / 10 ms release), and very high insulation resistance. Preferred in RF and semiconductor manufacturing equipment.
Reed models (GR series: GR2DNA, GR3BJA335, GR5LTA/B, GR5MTA, GR6HBA318, GR6JNB218) are used in low-power and precision-timing applications, telecommunications, and test equipment — operate times of 0.8-3 ms and very low coil power.
Gas-filled models (G series: G61, G61L, G62L, G64, G64L, G71, G71L) are used in extreme high-voltage applications (35-70 kV) for make-only switching — satellite communications, submarine cable, high-voltage testing, and aerospace.
All models feature patented ceramic sealing technology, stainless steel housing, and long service life.
