DAR72410-HR

D-HR Series High Insulation Resistance, High Voltage Relays -10kV & 15kV 10kV or 15kV Isolation Low Contact Resistance 1x1014 Ohms Minimum Insulation Resistance PCB or Flying Leads Connections Ideal for sensitive test and measurement circuits which require low leakage current losses Contact Specification Unit 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 Very high isolation voltages - up to 15kV are achieved through the use of high vacuum reed switches with either rhodium or tungsten contacts which 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.
