Denpetec Induction Heater, 12-48V 2500W ZVS High Frequency Induction Heater Heating PCB Board Module Flyback Driver with Copper Ring

Product works as intended, before powering up make sure to spread the coil out.

Out of the box, it had a bunch of loose screws and brass columns rattling around so I wasn't optimistic at that point. It wasn't difficult to figure out where they all went. I hooked it up using 24v 25A power supply and 20000 uf capacitor, it works great. Heated an old junk screw driver to red hot within a minute. The fans kept all of the components nice and cool during that period. Only thing that got a little warm was the traces on the bottom of the circuit board on the output end. I did not hook up a pump for water flow through the coil when i was testing it out but I would say it's not really necessary for short intervals. My copper tubing barely got warm. I originally bought it for tesla coil experiments with my boys. It only delivers a 39khz pulse the way it comes from the factory which is not high enough frequency for the coil we designed. There are ways to change the frequency but I think I will just leave it be for now as an induction heater. It will still be around if I get bored with the spark gap and the solid state tesla coil builds

I hooked it up to a 12 volt 100 amp hour battery and it heated the metal, it won't get red hot with that little of volts but it works.Going to make a 48 volt power supply.Make sure the coil is connected before powering it on and becarful on the power supply, you need instant power. These new power supplies that slowly power up will burn out some things inside. Capacitors after the power supply and make sure they are juiced up with the power before switching onto the board.

as above. working on a power supply that will do 48v 50a, will upgrade review if that works.Update: didn't work even with the new power supply. I'm going to request a refund even though the window closed.Waste of money.
