Question
John Kalaigian –
Hello, curious to know if this SSR is a worthy mate for a Keenovo 120V 750W pad for my CR-10S. Thanks!

Tim Hoogland –
Yes it will! We’ve even used them on the 1500W S5 heaters. It handles it with no issue.

What gauge wire should be used?
(0) (0)
Tim Hoogland –
Depends on how many amps your bed pad uses. Typically 14 gauge would be used for up to 15A current draw and will cover anything under 15A as well. I would not recommend using anything lower than 16 gauge for an AC bed. If you want to be sure what gauge to use contact the manufacturer of the heated bed pad and see what they recommend. We only sell the SSR, not the pads. The SSR is rated for up to 25A current which is more than enough for the heated bed pads used on 3D printers.

Question
Jennifer Bonnette (verified owner) –
I plan on using this SSR with an AC heated bed for my CR-10 S4. Does this SSR need a heat sink?
(0) (0) Watch Unwatch
Tim Hoogland –
If using it at under 15A you can just mount it to a metal surface like the printer extrusion or a case. Above 15A we recommend you use a heatsink on it.

Can this SSR be used with PID bed temp control?

Tim Hoogland –
Yes, it can. They work prefect with PID temp control.

Question
Murray King –
Would this relay work with a SKR mini e3 v3 board for the power down feature. The board has the terminals for the control side and the capacity seems to be large enough unless I am miss understanding how that all works.

Tim Hoogland –
I am not sure of that since we don’t sell or use the BTT boards. It would be best to contact BTT to see if you can use an SSR for that function.
