D SERIES
HIGH VOLTAGE RELAYS 10KV & 15KV
Very high isolation voltages, up to 15k
V
,
a
re 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 H
V
,
i
nclude PCB, solder turret (wire wrap),
flying lead and 0.25” spade terminals.
Features
• 10kV or 15kV Isolation
• Low contact resistance
• PCB or panel mount
• HV connections via flying leads, solder turret (wire wrap),
or 1/4” spade terminals
• Excellent AC characteristics
