If you ever have a project that uses the SSR at 100 amps, you very definitely need heat sinks for them. There are SSRs for DC, but only pretty low current.Paul
THANK YOU! I AM BUILDING an induction launcher that can vary the strength and frequency of what is launched, a few times per second.I am using two electromagnets, one to launch and the other to be launched. The strength needs vary from enough to be repelled to enough to lift 3lbs 1 foot high.For the electromagnets I don't know the gauge of wire to be used or how many turns so don't know the area. I want to focus on how many Amps I can even get and will use that for finding out the wire gauge and turns.FOR NOW I need to focus on the relay, mosfets? were suggested - and yes I do believe I need DC amps for the electromagnets. Since Amps mean current and current is good I need to find out just how many amps I can work with the Arduino Uno and how to connect everything correctly.I would appreciate some suggestions as for components.
So if I use mosfets how would I connect them to the Arduino, wall outlet for power and to each electromagnet? Can I get an electrical diagram.And how many amps do I even need to lift/launch 3lbs 25cm?
