DAR72410U.

## **DA(UL) Series** 

## **UL Approved *, Normally Open, High Voltage Relays - 10kV** 

## _**10kV 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**_ 

_Recently approved by UL, 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._ 

_The Rhodium contact relays have low contact resistance, while the Tungsten contact relays can switch higher voltages._
