Solid State Relay (SSR) Switch mains power with a microcontroller. Careful!

$16.00 Inc. GST
On order

A Solid State Relay (SSR) allows you to switch on and off mains powered devices with an Arduino or other micro-controller.

These Zero Crossing Solid State Relays are controlled with 3 - 32V DC and can switch 24 - 480V AC at up to 25A with a switch speed of less than 10ms

Dimensions: 57.4mm x 44.8mm x 31.5mm

  1. Do you have a spec sheet for this product?

  2. Hi Ben,

    Sorry no we don't have a datasheet for this.

    Cheers,

  4. I know is says 3-32V input, but just confirming 3.3V will be enough to switch it? Looking at controlling it from a Raspberry Pi.

    It would be also good to know the input current, I think these solid-state relay inputs drive an opto-coupler, which could draw in the 10 of mA.

  5. Hi Geoffrey,

    3.3V is enough but the Raspberry Pi possibly doesn't have enough power from the GPIO to switch the SSR.

  6. Hi,

    Just wondering if these can be used without a heat sink. And can you recommend any heat sinks if required?

    Cheers,

  7. Hi Sam,

    Sure, a heat sink isn't required to use these, you'll only need one if you want to do up near the maximum current rating. You would need to test for your individual situation but imagine that if you were doing 10A you would be okay without one.

    Cheers,

  9. Thinking of using this relay for switching a 12v DC wiper motor drawing 15amps approx.
    Motor may draw 15amps constantly or intermittently. Is this relay suitable. Thanks GH.

  11. Hi GH,

    No it's not, this is an AC only SSR.

    Cheers
