Treedix 5-12V ZVS Low Voltage Induction Heating Power Supply Module with Coil Power Supply Heating Power Supply Module

Works great as a dynavap induction heater. I decided not to mount mine in a box and have 6 coils on one side and 4 on the other. 6 coil side is for first heat up - about 6 seconds - and 4 coils for follow up heating. I could use the 6 coil side entirely, but I have to be quick about removal or I'll combust. The 4 coil side has a 12s heat up on first go and 6s follow up but combustion is less likely.

I bought this to sterilize x-acto blades and hypodermic needles inside my still air box so I don't have to use a torch outside of it.I used an ATX power supply turned bench supply and knocked out a quick 3d printed case for this. It works great for knife blades, it'll get 3/4 of the blade red hot in 5 seconds or so. It doesn't work well on hypodermic needles, however. It does heat them, but just barely. I don't know if they aren't ferrous enough or if they're just too small, but it just won't heat them hot enough to even boil water inside.But, for $10-ish, it still saves a ton of time. While it would be nice if it worked for syringes, if I had to choose one or the other, I'd rather it work on knife blades.

This is a neat circuit for experimenting/demonstrating induction heating, but the circuit is highly is highly fragile and prone to burning out the power mosfets if too much mass is being heated or if the metal isn't placed absolutely in the center of the coil. This is the second one that I burned out after using the first one for less than 24 hours. The moment it burns out, you'll see a small puff of white smoke come out near the toroidal inductor, the power LED will stills stay on, but will no longer heat up. Because of how delicate this is, there's really not much you can use it this circuit for other than heating up paperclips

Here is how to use out of the bag.2 inputs on one end with a positive and negative for power.Other end has 3 inputs, plug the coil in the 2 end slots leaving the middle one empty.I used a 9v just to try it out. A little blue light comes on near the power inputs when it has power on.It is very solid and looks professionally made. I recommend this product.

This product is super awesome. I just hooked it up to an old computer power supply I had, the yellow wire to the positive and the black to the negative and jumped the green wire to ground. Make sure you solder the coil to the PCB board and don't rely on the plastic connectors! This unit heated up my hobby knife blade red hot in about 3 seconds!
