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.
