Welcome to HV Relays - Information About High Voltage Relays

This site provides the latest information about the leading world suppliers of high voltage relays, vacuum relays, RF Relays, and gas filled relays used for test, manufacturing, medical, and research equipment, and for radios, radar, sonar, and other applications where high voltage & RF switching is required. This site provides a directory of the suppliers and their part numbers, application information, links so you can compare products, and some tips that can help you in your product selection process.  

We have listed the world’s leading suppliers and plan to expand this site to include more on applications. Hopefully you will find this information useful and that you will send any suggestions for improvement to info@hvrelays.com.

COMPANIES:

Listed below in alphabetical order are the major suppliers, past and present, of HV relays. If you know of other companies you feel should be added, or if you are a manufacturer and would like to be considered for listing, please send your information to us at info@hvrelays.com.

  • Cynergy3

Cynergy3 (previously Crydom) specializes in a variety of semiconductor, liquid level and high voltage vacuum reed relays rated up to 15 kV. Reed relays generally do not switch above 300 watts and are not as rugged as ceramic types, but they are superior for long life, fast operate time and the lowest cost. The Cynergy3 brand was created after the Crydom-branded solid state relay line was sold to Schneider Electric in 2006. Cynergy3 is located in the UK and sells its relays using manufactures Representatives & distributors. They also act as a manufacture of HV reed relays for some of the other high voltage relay manufacturers listed below. www.cynergy3.com

  • GIGAVAC (fully compliant RoHS relays)

GIGAVACis considered the darling of the high voltage relay industry and use the tag line “Today's Expert in High Voltage Relays”, which some people say they are. They were founded in 2002 by the management team that built Kilovac before the Kilovac brand was sold to Tyco. Their Chief Scientist, now deceased, was the VP of Engineering for Jennings Technology and held most of the patents for the relays used in the industry today.  GIGAVAC offers possibly the largest selection of high voltage relays and sealed DC and AC contactors in the world, nearly all fully RoHS compliant, and use a wide range of technologies including reed, vacuum, ceramic, gas filled and their exclusive EPIC™.

seal for their contactors. GIGAVAC products are manufactured in the US, the UK and China and they claim they have the lowest costs in the industry.  They have real people answer the phone (unless they are closed) and encourage users to draw on their wealth of application knowledge free of charge. GIGAVAC is located near Santa Barbara, CA and sells its relays through manufacturers’ representatives, many whom have sold Kilovac or Jennings relays for years. GIGAVAC acts as its own distributor and says they have over 250 finished part numbers in stock and ship most orders the same day the order is received. GIGAVAC has no minimum purchase requirements and accepts most major credits cards. www.gigavac.com

  • Jennings Technology

Jennings Technology high voltage relays have been around since 1942 and was once considered the industry leader. They pioneered many of the high voltage vacuum relay designs used in the industry today. Over the years, Jennings was acquired by conglomerates such as ITT, Lear, Joslyn, Danaher and most recently Thomas & Betts. Other than possibly ITT, each sale is said to have caused Jennings to loose market share. Their VP of Engineering became the Chief Scientist for GIGAVAC that was formed by the previous Kilovac management team after Tyco bought Kilovac. Jennings technology has vacuum with some gas filled high voltage relays. They do not say they offer fully compliant RoHS relays nor do the sell HV reed relays. Jennings is located in San Jose, CA and sells its high voltage relays direct, through manufacturers’ representatives and distributors. www.jenningstech.com

  • Tyco Electronics, Kilovac brand

Tyco’s registered trade marked Kilovac brand high voltage relays have been around since 1964. Tyco purchased the Kilovac brand in 2002, which is said to have prompted the previous Kilovac management team to form GIGAVAC. Tyco supplies sealed reed, vacuum and gas filled high voltage relays but do not say they offer fully compliant RoHS relays. They sell their high voltage relays through the Tyco sales and distribution network. www.tycoelectronics.com

APPLICATION NOTES:

All of the suppliers have some application notes on their web site. Because the information is copyrighted, we are unable to compile it on this site. GIGAVAC has the most complete information and has given us permission to list their index below with links to their site.

RoHS COMPLIANCE:

Buyers beware The RoHS standard exempt relays rated above 10kV. Less ethical suppliers say they are in compliance even thought they know their products exceed the RoHS maximum content of lead, hexavalent chromium, mercury, PBB, PBDE and cadmium.

Today, only GIGAVAC has certified their high voltage relays as fully compliant and meets the intent of the RoHS standard with a maximum 0.1% concentration by weight in homogeneous materials of lead, hexavalent chromium, mercury, PBB and PBDE; and a 0.01% concentration of cadmium.
