Introduction - High voltage ceramic vacuum polarized relays are relays that use polarized type electromagnetic actuator in a vacuum chamber to switch high voltages and frequencies. - They have advantages over conventional relays, such as… Read More »What is a polarized relay?
A high voltage ceramic vacuum relay is a relay that uses ceramic vacuum sealing to isolate the relay contacts from the outside air and provide high breakdown strength for relays operating in high voltage circuits. The vacuum sealing prevents the formation of… Read More »What are high voltage vacuum relays?

-30kV High Voltage Vacuum Relays - SPST (Single Base Single Throw) - There are two versions available: a) MGV20A (SPST-NO, Normally Open) b) MGV20B (SPST-NC, Normally Closed) -High voltage switching - screw connection. - Relay fastening - through, under a carving.
High voltage vacuum relays can be applied in various fields such as radar systems, ESD pulse generating equipment, high voltage test equipment, high voltage power supplies, airfield lighting systems.
As everyone knows, high-voltage relays are called relays that switch circuits with voltages over 500 V and high currents. Precisely because of the ability to steer gigantic powers, relays are used in aerospace RF applications. This equipment requires compact relays that have low RF overhead, have unsurpassed dielectric properties at high voltages, and are capable of operating at high altitudes under harsh weather conditions. Other than that, extensive use of relays has been found in medical equipment and all sorts of commercial applications.
