Would this work to lift large metal plates with a hoist?

It would not be safe and that is not the intended use; if and when the magnet loses power even for a milisecond, it disconnects by design.

There's no wire with this and I don't think I could add any if I tried. The screws on the connects don't turn. How to install?

Hi, please unscrew the screw on the front panel, then you can see 2 connects V+ and V-, connect them to your 12V DC power supply control with wire and it will be OK. thanks.

I’m building a magnetic hold to process metal parts after plasma cutting. With 3 of these how many amp power supply do I need?

I'm using a 12 volt, 500ma power supply to power two locks.
