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.
