DB(UL) Normally Closed High Voltage Relays

Cynergy3 / Sensata DB(UL) Normally Closed High Voltage Relays are designed for high-reliability applications. The UL-approved relays feature very high isolation voltages (10kV, 7.5kV, 5kV) and high vacuum reed switches with either rhodium or tungsten contacts. The rhodium contact relays have low contact resistance, and the tungsten contact relays can switch at higher voltages. Cynergy3 / Sensata DB Normally Closed High Voltage Relays applications include cardiac defibrillators, test equipment, and high voltage power supplies.
