GIGAVAC, today's expert in high voltage relays, announces the G23—a brand new 15 kV Double Pole Double Throw (DPDT) vacuum relay. The G23 combines molybdenum moveable contacts with copper stationary contacts to provide low, 10-Milliohm contact resistance for increased current carry. The low, stable contact resistance provides low voltage drop in DC circuits and low signal loss in RF circuits.
The G23 incorporates oversize contacts and a strong actuator that give a high continuous current carry rating of 75ADC. In addition to high continuous current carry, the G23 can hot switch under load in most circuits. All of this capability is efficiently packaged into a relay that measures approximately four inches by two inches. The G23 is available with a nominal 26.5Vdc coil, which is ideal for drive circuits from 20Vdc through 28Vdc. Because of its load switching capability, the G23 has been designed into switchgear systems for critical airport lighting installations. Special coils can be provided to meet customer requirements
