DAT70510F-HR

## **| D-HR SERIES** 

## HIGH INSULATION RESISTANCE, HIGH VOLTAGE RELAYS, 5KV, 7.5KV, 10KV & 15KV 

Very high isolation voltages, up to 15kV, are 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. 

## Features 

- 5kV, 7.5kV,10kV or 15kV isolation 

- Low contact resistance 

- Insulation resistance 1x10[12] Ohms minimum, 1x10[14] Ohms typical 

- PCB or flying leads connections 

- Ideal for sensitive test and measurement circuits which require low leakage current losses
