HV Relay RF Relay JPK-47A SPST-ON Vacuum Relay Switch High Voltage DC8KV Carry 12A Current Coil Voltage 26.5VDC


ceramic vacuum relay is a ceramic vacuum seal that isolates the contact point seal of the relay from the outside air to obtain a high withstand voltage for high-voltage relays, which are commonly used in high-voltage circuits.  since there is no air, the contacts in the vacuum are not oxidized, so the contact resistance of the vacuum type relay is small and stable. Particularly suitable for use in RF applications. A typical ceramic vacuum relay consists of four basic parts: a sealed arc extinguishing chamber with a contact point inside the arc extinguishing chamber for high pressure resistance. An armature mechanism that moves the movable contact. Powered coil section. An additional part that is easy for the user to install and connect.
