D-HR SERIES
HIGH INSULATION RESISTANCE, HIGH VOLTAGE RELAYS, 5KV, 7.5KV, 10KV & 15KV
Very high isolation voltages, up to 15k
V
,
a
re achieved through the use
of high vacuum reed switches. Rhodium or tungsten contacts 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, whilst the
tungsten contact relays can switch higher voltages.
