DAR70510FU

## **| DA(UL) SERIES** UL APPROVED*, NORMALLY OPEN, HIGH VOLTAGE RELAYS - 10KV, 7.5KV & 5KV 

The DA(UL) series is a UL* approved 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. 

A choice of 5kV, 7.5kV and 10kV isolation voltages is available. 

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. 

## Features 

- Choice of 10kV, 7.5kV or 5kV 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
