Hi! For a project I am designing a system of very high-power electromagnets. Each electromagnet is fed a current of around 75A. To allow them to cool, I alternate between feeding power between one and the other around every 10 seconds or so. The device is controlled by a master raspberry pi or arduino and I am struggling to figure out an effective relay type switching device that won't break the bank. Any help?
Just in general: Do you really have to switch them on/off?I guess if you gradually regulate them on and off that should be easier to handle.That just came to my mind but I am not an expert.
