Relay beefs up performance

Relay offers years of failure-free operationGIGAVAC said its new G9 sealed single pole, double throw (SPDT) 15kV, 75A vacuum relay solves size, weight and cost issues for 30A to 75A applications. The G9 relay also touts years of failure-free operation with tungsten contacts sealed in a vacuum which locks out external contamination. Plus, it can hot switch lower current loads.

"Up until now, customers with applications up to 15kV, with currents above 30A had to buy a much larger and more expensive relay," said Jim Lanum, GIGAVAC's VP of sales, in a statement. "So GIGAVAC developed the all-new G9 mid-range 75A relay that fits between our G8 relay rated up to 30A, and our hefty G50 that will carry up to 110 A. The new G9 saves the customer more than 35 percent in relay costs and makes their system much smaller."

The G9 relay is available with coil voltages of 12-, 26.5- or 115Vdc, or a custom rating. It also incorporates the company's exclusive changeable coil feature that allows users to switch the coil even after the relay has been installed. Measuring 58(H)-by-60(W)mm (including terminals), the new relay comes with screw terminals for easy connections, and flange mounting that keeps the high voltage and control circuits far apart to eliminate cross talk and any chance of high voltage shorts to the coil circuit.

The G9WF model is priced at $267 each, plus transportation and handling, in quantities of 25 units. Delivery for the most popular models is from stock with lead times of four weeks for special orders.
