Recently approved by UL, very high
isolation voltages (up to 10kV) are
achieved through the use of high vacuum
reed switches with either Rhodium or
Tungsten contacts and make these relays
suitable for high reliability applications,
such as cardiac defibrillators, test
equipment and high voltage power
supplies.
The Rhodium contact relays have low
contact resistance, while the Tungsten
contact relays can switch higher voltages.
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.
