Recently approved by UL, very high

isolation voltages (up to 10kV) are

achieved through the use of high vacuum

reed switches with Tungsten contacts and

make these relays suitable for high

reliability applications, such as cardiac

defibrillators, test equipment and high

voltage power supplies.

The Tungsten contact relays can switch

higher voltages, up to 7000Vdc/ac peak to

peak

PCB or Panel Mount, via Nylon studs,

versions are available.

Connection options, for the HV, include

PCB, solder turret(wire wrap), flying lead

and 0.25” spade terminals.
