PICKERING ELECTRONICS Series 100HV high voltage SIL/SIP reed relays are rated for up to 3kV stand-off voltage and with more than double the coil resistance of previous devices. Device suits applications such as transformer or cable testing or any other automatic test equipment where high voltages are involved but where low coil power consumption is required. Three types of dry switches are available, capable of standing-off 1.5kVdc, 2 kVdc or 3kVdc. The 3 kV version features increased clearance between the switch and coil pins to accommodate the higher voltage. Higher voltage versions are available on request. Product series features an internal mu-metal screen to facilitate close stacking without risking problems caused by magnetic interaction.
