DB(UL) Series UL Approved* Normally Closed, 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 Contact Specification Unit Contact Form Contact Material Isolation across contacts kV Switching Power Max. W Switching Voltage Max. V Switching Current Max. A Carry Current Max A Capacitance across pF contacts Lifetime operations Recently approved by UL, very high isolation voltages (up to 10kV) are achieved through the use of high vacuum reed switches with Tungsten contacts and make these relays suitable for high reliability applications, such as cardiac defibrillators, test equipment and high voltage power supplies. The Tungsten contact relays can switch higher voltages, up to 7000Vdc/ac peak to peak 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.
