So I picked up a dust collector and was initially happy to see in the manual that it only required 7.5amps to operate. Great, I’ll power it through through the Vacuum outlet on the onefinity. That didn’t last, the fuse was promptly blown because the motor startup current was more than it could handle.
Since I really wanted to control it via the flood coolant setting on the Masso, I sourced a solid state relay (SSR) to make my own dust collector control that was activated by the onefinity vacuum port. Finished my prototype today and it works so I thought I would share. This will work for 120V or 220V powered dust collectors at any current requirement up to 20 amps (25 amp startup).
Attached are the step files for the box & cover as well as a drawing on how I wired it. The SSR that I used can be found on Amazon here SSR-25AA Solid State Relay AC to AC (Input 80-250V AC Output 24-380V AC) with Heat Sink, 25A : Amazon.ca: Automotive
I would recommend that if you want to try this and you don’t know what you’re doing with electrical work, to find someone who can do it for you as you wouldn’t want to burn your shop down or worse, electrocute yourself.
Edit: Noticed that the drawing that was a SVG wasn’t showing up. Removed and replaced it with a PDF version.
