hello! not sure if this is in the correct place but.....
I am trying to come up with a way of switching a high current load.
I have an electromagnet that I want to pulse on for around 60ms, it draws around 90A at 12V DC. it will only switch once every few seconds at the most.
I have looked at SSR's and it seems that I need one made for DC current, not zero switching. my question is do I need one rated for the full 90A or as its a short pulse can I get away with running a lower rated unit?
Any other suggestions?
