Product Details

Cynergy 3 DA (UL) Series Reed Relay

The UL approved reed relays have very high isolation voltages. UL reed relays are ideal for applications that require high reliability, these include cardiac defibrillators, test equipment and high voltage power supplies.

Features and Benefits

10kV isolation
Low contact resistance
Panel mount or PCB
HV connections through Flying Leads, Solder Turret (wire wrap) or 1/4inch Spade Terminals
AC characteristics


The rhodium contact relays have low contact resistance, the tungsten contact relays can switch to higher voltages.
