High Power ZVS Induction Heating Module 1000W DIY Metal Heater with Copper Tube for Gold Silver Smelting Melting

I have quite a bit of experience working with electronics, machine controls and cnc installations, and was very disappointed after installing this item. After installing I hit the start button, and nothing happened. I tried a few times and when I checked, there was a voltage drop (to 5.6v dc) and the heat sink got quite warm. I had a spare power supply and swapped it out with no change. There is no noticeable damage to the unit, it just failed to work. I had the timer relay set to 3 seconds and that probably kept the board from melting. Just a piece of junk I'm stuck with.

This product has a lot of potential. It needs some sort of chip that would help regulate/control everything so that it doesn’t completely die on you after only a few melts. I also think the posts should be below the board so that water doesn’t move across the top of the board. It feels like an early stage model of something that could be really great, but as it stands, unless you know how to work these things, save your money. I’ve gone through about 10 of them and finally said to h*ll with it I’m going to get something else. However, if you are going to try one, some helpful things to know (because it doesn’t come with instructions or a support/help service):1) You’re going to need to get a transformer to boost the 110V. 120/130 minimum is needed to melt copper.2) Move the three prong posts to underneath the board. Be careful not to damage the board when removing the solder.3) Electrical tape helps a lot. Cover up the shorts or exposed copper on the board. The board isn’t flimsy, but the seal/coating is extremely thin and will scratch off if you look at it wrong.4) You MUST absolutely MUST wait between 1-5 minutes after plugging in the 48V power supply (sold separately, and not to be confused with the transformer to boost the voltage)* before switching the board on. Otherwise it will die instantly and there’s nothing you can do about it.5) Get insulating fiber to wrap around the copper coil. If you don’t, you’ll sure find out why.6) The water gets very hot very quickly. Once it hits like 100F switch it off and let everything cool down. This happens very quickly. Even with a large metal tank filled with ice.7) Don’t let the crucible touch the insulating fiber - it’ll melt.8) Do not switch the board on unless there is a crucible in the coil. Place the crucible into the copper coil before switching the board on. Switch the board off before removing the crucible. Do not run the board with nothing in the coil. Ever. At all. For any amount of time. Period.9) Use metal hose clamps and don’t over tighten to secure the water hose to the copper coil tubes.10) Be sure the metal clamp that spans the three prongs on each side is as tight as possible. You want as much contact with the copper coil tubes as possible. It must go over the middle one, not between the posts.*There is the ZVS board, the step up from 110V to 120V/130V (even 140V if you want) transformer, as well as the 48V power supply. All three things are required in order for this system to operate. Plug the transformer into the wall outlet, then the 48V power supply into the transformer. The ZVS board connects to the 48V power supply, via two copper wires with a circuit breaker running the red/positive line. After powering on the transformer, plug in the power supply, and it will kick on. You must let the voltage in the 48V power supply stabilize for around 1-5 minutes before switching on the circuit breaker to activate the ZVS board. There shouldn’t be any change in noise coming from the 48V power supply when you switch on the board. If you hear the 48V power supply kind of like rev up or speed up to a faster/higher pitch, you fried the board and you now need to get a new one. You didn’t wait the 1-5 minutes, did you? Don’t get the board wet.Best of luck to anyone who is brave enough to give it a shot. Hopefully this long post helps someone. Knowing all of this before hand would have saved me so much time and headache/heartache. There isn’t much info out there, so keep this info close in hand as a reference. Trust.

I rarely leave reviews but seriously save your money.It doesn’t come with instructions, even so you’d think it would be fairly intuitive. Hook up your psu, then attach the coil.Well, the bronze tabs your given don’t line up with the holes, when you try to put them in place they no longer hold the coil, so after using the most solder I’ve ever used fixing them in place, it doesn’t do jack but heat the coil, almost no Reaction with steel.Did I do something wrong? Maybe. Does this unit have potential? Maybe. But with no instructions and putting it together how it seemingly should. Garbage

I have the same issue as others. I use the proper power supply and it suffers a voltage drop to 5 volts, heat sinks get hot and nothing happens. I order two and both had the same issues. I also tried 3 different power supplies.Save your money and get something else.

Dont buy it. Great attempt by them though.
