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,

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.
