Industry-first 20kV stand-off relay from Pickering for high voltage switching
Pickering Electronics has introduced a new 20kV addition to its long-established high voltage Series 63 range. This latest addition offers 20kV stand-off across the switch contacts.
The new relay is designed for demanding high-voltage applications, featuring up to 20kV stand-off and 12.5kV switching at a maximum of 50W. Tungsten-plated contacts ensure a long and reliable life, supporting up to 100 million operations when cold switching. Ideal for a variety of high-voltage testing and switching applications, including hi-pot testers, high-end cable testers, electric vehicle (EV) charge point testing, solar energy systems, medical equipment and high voltage instrumentation, Series 63 is also available with fast lead times of 3-4 weeks for orders of up to 200 pieces, and 5-6 weeks for larger quantities.
The Series 63 20kV reed relay offers features including a compact PCB mounting with push-on HV connections on the top face, supplied with appropriate connectors and insulating boots. Both Form A (energise-to-make) and Form B (energise-to-break) configurations are available, with 24V coils, and it is usually possible to achieve a Form C (change-over) function by using a Form A and a Form B type together. An internal mu-metal magnetic screen allows Form A versions to be mounted side by side without interference, and an optional electrostatic screen and/or earth connection to the magnetic screen offers enhanced EMC protection. Maximum switch current is 3 Amps, with maximum carry current of 3.5 Amps.
