Manufacturers : Electronic components : Relays : High voltage relays

Electromechanical switching relays have long been used for years to switch high voltages from a source to a load. The relay operates by passing a current through a wire wound coil to create a magnetic field which is used to close the relay. Vacuum type and other sealed relays are in common use for high-voltage switching, and are typically either evacuated to a high vacuum, or evacuated and backfilled with a dielectric gas such as sulphur hexafluoride. These relay devices are widely used in communications equipment, high-voltage power supplies, and other electrical apparatus requiring rapid and dependable switching of high currents at high operating voltages. Vacuum relays can be equipped with varying types of driver systems. Usually, an electromagnet, having a clapper-type armature is used for this purpose. The contacts of vacuum relays are enclosed within an evacuated envelope, and contact deterioration is materially reduced. Advances in solid-state switching and relay technology have made possible the replacement of many electromechanical switching and relay assemblies. Solid state relay devices have been developed for power control systems with long life, quiet operation and other associated advantages.
