I'm looking to wire up a relatively simple induction heater (cheapo Chinese board you can get on Amazon/eBay). What I want to be able to do is turn the heater coil on for some pre-specified amount of time before turning it off again, and repeat.
My initial plan was to wire up the 48V power supply through a relay of some sort into the heater, and drive the relay coil using a 555 timer circuit. Problem is, I can't seem to find something rated for a high enough contact current at 48VDC (that doesn't cost in the range of $100). Can anyone point me in the right direction? I'm hoping for something in the range of 20A or higher. Thanks.
