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

Perfect for dynavap, you'll need to find your sweet spot cause it clicks fast no matter what unless you modify it to induce a smaller area. Will make a small bolt or nail red hot possibly liquid (I haven't pushed it that far) you absolutely need to solder these connections to the sides of the board. It functions in the ports but with a load it will start to melt the plastic casing for the output ports.

The media could not be loaded. So Amazon sent me another coil and it works this time. It said that a power supply doesn't work but I have a 10 amp power supply running this and it works. Just make sure you buy some good quality solder. Rosin core for electronics. The pipe solder doesn't work. But I give it a 10 out of 10 this time

I finally tried using this (purchased summer of 2023). Tried to power it using 30V 10A bench power supply at 5V/10A. It made a high pitched noise and the PCB smoked slightly near the soldered connections. It didn't heat a small stainless steel tube at all. Seems to be completely defective.-- update --The device does work, but only when used with a fast rising voltage. Using a bench power supply set to 12V a momentary push button switch drew about 4-5A. A small stainless steel tube (~4 mm diameter) did heat up, but not to red-hot.

This induction heater power supply works great. Mine has been used daily for weeks and is doing a good job. Tips: do not run the induction heater without a ferrous metal object in the coil, or else it could burn out.Also, it's important to do a test of new units to make sure the work before beginning on your project. Getting a bad one is rare, but can happen.I've had three other induction heater power supply modules that have been working for years. This brand has been very good, so far.

Buyers of this should be aware that soldering the coil to the board is very strongly recommended by the insert documentation, and to do that you’ll need an actual soldering iron with some decent wattage due to the mass of what needs to be heated to make a good joint. (The 4xAA battery-powered iron I had was not up to the task.)Also, one of the capacitor connections on my unit was broken and I had to resolder it myself. Not a big deal, just annoying.

Just seems to overheat at the transistors and not do much else..

Instructions made the assembly very easy. It helps if you have a soldering iron. I also recommend adding a momentary push button and installing everything inside a small project box - just make sure That the coils do not touch the box wall (make larger holes; You could also insert some porcelain rings to ensure the coil wire would not touch the plastic wall).Works great with my small projects in the shed, I’m sure you can use it for jewelry work and other similar type projects. This was a fun and useful purchase.

Bought mostly out of curiosity. Works very well for SMALL metal objects and will come in handy for my model building.
