UK made: Pickering high-voltage reed relays have lower power coils

Series 100HV high voltage reed relays are available with a choice of three dry contacts, capable of standing-off 1.5, 2 or 3kVdc – the 3kV version has increased clearance between switch and coil pins. Higher voltage ratings are available by special order.

“Where mains voltage are switched, for example to control and isolate SCR or triac gates, they are an ideal choice,” according to the company. “In mixed signal applications the lower coil power reduces the thermal EMF voltages generated across the switch.”

This range is available with one or two switches in a single package in 1 Form A, 2 Form A and 1 Form B configurations (see table). 5V, 12V or 24V coils are available, and an optional internal diode can be specified.

An internal mu-metal screen minimises magnetic interaction when the devices are stacked closely.
