Gigavac's DPDT high voltage relays
September 2011
Electrical Power & Protection
Gigavac has announced three new 15 kV DPDT compact high voltage relays – models G2SPD, G8SPD and G15SPD. The G2SPD has copper-molybdenum contacts for 50 ADC current carry and to provide low, 12-milliohm, contact resistance. The low, stable contact resistance provides the desirable low voltage drop in DC circuits and low signal loss in RF circuits. The G8SPD and G15SPD have tungsten-molybdenum contacts which allow for the relay to be used in load switching applications. The G15SPD uses a unique gas mixture that is particularly suited for loads such as capacitance discharge applications.
These new relays can be applied where two SPDT relays were used in the past. All models have two sets of mechanically connected SPDT contacts to provide the flexibility of using one set as auxiliaries to monitor status. The relays are ideal for drive circuits from 8 through 28 VDC with special coils available to meet unique customer requirements.
