High speed relay 1

[workexperiencekid]

G'day!

I'm needing a relay with a very fast switching speed to control a circuit. Do you know what are the fastest relays that are available in the market?

Cheers,

Time is money. How fast can you afford to go??

Do you need solid state or mechanical? Current and voltage? DC or AC? If AC, HF? Maximum frequency?

An ordinary little reed relay switches in 50 - 100 microseconds. That is fast. But contacts cannot take much load. Solid state switches (IGBTs, MOSFETs) switch in a few hundred nanoseconds and can carry hundreds of amps and thousands of volts. But have some zero crossing distortion. Good for DC, though.

A standard relay switches in milliseconds and a contactor needs ten or twenty ms.

You need to specify your needs better if you want a specific answer.
