On the Elite Power Supply, is the Vacuum outlet connected to a mechanical relay or to a SS relay?
I have a vacuum motor that is 1 HP, 7.4 A FLC. The current rating is within specification (12A, w/ 10A fuse?) but I am unsure whether it can handle the inductive load of 1 HP. There is no HP rating for the relay.
I don’t have an official answer for you, but the receptacle on the US power supply is NEMA 5-15R, which means 120V @ 15A, but the fuse is only rated at 10A (Elite Masso Power Supply Fuse Schematics FAQ) as you indicated. I’ve seen this a lot where the receptacles are only rated for 10A even though they use a 15A standard. In fact it’s actually quite difficult to find a reasonably priced receptacle that is actually rated at 15A and even more difficult to find one at 20A.
Based on a different thread, it looks like the vacuum is solid state with an MOV across the supply line. I can’t see the part number for the FET (or TRIAC) but I’m guessing it’s not rated for 20A based on the size and the lack of a heat sink other than the copper on the PCB and the via stitching.
If you are adventurous, given the power supply has a fuse, you could try it out and if you fry the fuse simply replace it?
Hope this helps.

Thanks for the response. I appreciate the link for the picture of the inside of the power supply. However, it does look like OF is using a electro-mechanical relay for the Vacuum. Also appears there is a MOV and a RC network for contact arc suppression. My next question is, are the relays pluggable and what manufacturer and part number of the relay so I can do more research on this component. I do not have my Elite system yet. A few more weeks yet.
The picture appears to show a common G2R relay (10A, 250V) that is soldered in.
I decided not to take the chance with this relay. So I will install a small enclosed 24 vac transformer under the bench that plugs into the Elite power supply vacuum outlet. The 24 vac will then operate a small (24 vac coil) contactor HP rated for my dust collector. I used 24 VAC to avoid having two separate 120 vac sources in the same enclosure.

Please let us know how this works out for you. I have a similar dust collation setup. Would love to have Masso to start and stop it.
