Pickering Electronics has released the Series 100HV high voltage SIL/SIP reed relays rated for up to 3kV stand-off voltage and with more than twice the coil resistance of earlier devices. This is ideal for applications such as a transformer, cable testing or any other automatic test equipment where high voltages are involved but where low coil power consumption is needed.
Commented Kevin Mallett, technical specialist at Pickering Electronics: “Where mains voltage is switched, for example, to control and isolate SCR or triac gates, Series 100HV reed relays are an ideal choice. And in mixed-signal applications, the lower coil power of the new relays reduces the thermal EMF voltages generated across the switch.”
Three types of dry switches are offered, capable of standing-off 1.5kVdc, 2kVdc or 3kVdc. The 3kV version provides increased clearance between the switch and coil pins to support the higher voltage. Higher voltage versions are obtainable on request. The series features an internal mu-metal screen to aid close stacking without risking problems created by magnetic interaction.
The new devices are offered with one or two switches in a single package in 1 Form A, 2 Form A and 1 Form B configurations. 5V, 12V or 24V coils with optional internal diode can be defined.
