Series D, Series HV High Voltage Reed Relays • Normally Open or Normally Closed Contacts • PCB or Panel Mount Packages The Series D Relays are PCB mount Hi Voltage Relays capable of switching up to 8kV (dc or ac Peak). They have a dielectric strength of 10kV. The DAR Series has very low contact resistance, useful in minimizing errors in instrumentation systems. The Series HV Relays are panel mount High Voltage Reed Relays capable of switching 10kV (dc or ac Peak) with a dielectric strength of 12.5kV. They are all available Normally Open or Normally Closed and have a life expectancy of millions of operations.
