High speed relay

High speed relay

(OP)
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,
Work Experience Kid

RE: High speed relay

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

RE: High speed relay

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.
