ZVS Driver Module 12V to 30V DC High Voltage Generator with Flyback Transformer Heater Coil Boost Power Supply Board for Induction Heating

The first time it was a hassle, because it came broken, it wasn't packaged right, but AMAZON, made it right, and had a new one sent. So, second time around, It worked like a charm on my SCALAR MACHINE, that works like a zapper for zapping and destroying all kind of diseases and parasites. Thank you so much, seller, you are a 100% legit.

The zvs transformer works incredibly well! To connect the wires, tie the 2 middle wires and put the in the middle connection. The other 2, doesn't matter which way you put it, it just connects on the other connectors. The 2 connectors on the other side are for power, up to 30v dc. I built a very powerful arc lighter with mine. No instructions are included but super easy to figure out!

Showed up on time and got exactly what I ordered. Warning though on first start up it had way more power than I thought and my arc jumped about 4-5 inches. So please be prepared if you’re going to run it at 24V.

All in all this is a score; both the ZVS driver and flyback transformer work great and the price is exceptional for the performance. With short runs at high power the flyback will warm up some, as would be expected when pumping such a wattage into a flyback secondary. The ZVS driver stays perfectly cool at its upper range of input power; the wide tinned traces certainly do make a difference. With CRT televisions becoming scarce it’s becoming a rarity to find good flyback transformers, let alone at a price like this.

Es lo que esperaba llegó en tiempo

There are many HV transformers and drivers out there, but most die within a few minutes of use. Not this board! It is very well designed and built with heavy-duty components throughout. It also runs very cool, due to the ZVF switching design and has a nice fan to cool the MOSFETS if you really push power through it.

Excellent board and flyback combo. Produces a 2+ inch steady spark.

Works as was advertized

No ha durado ni 2 horas de uso.

I retract my bad review, I improperly tested. The board works as does the flyback transformer Tested with 12v dc. Long arc from flyback.

Great product works all the time

It does what it says on the tin, power in, sparks out. I'd say if your're clueless on how to hook it up, please don't before educating yourself, HV is no joke. For people with no clue about Mandarin who are still here, the pin leading via the PCB to the big capacitor terminals marked [-] is GND of course, the other one is low voltage in. For the transformer, hook up the center tap to the center terminal of the tree position screw block, the other leads shouldn't matter how you hook em up. Don't run this module off with a non juicer, it needs a beefy supply. That also means that you don't want to run this off constant current mode from your lab bench power supply or you risk stalling one of the FETs which will overheat and, in a timely manner, will go kaputt. It's a good starting point if you need a HV supply, but beware: modifying the primary comes with changes in the resonant frequency of this Mazzilli circuit. At high power draw your board might release the magic smoke if you're not careful. So overall I'd recommend it as a starting point, but I definitely suggest rolling your own circuit if you need a bespoke supply (Piernas Francisco's comes to mind). If you do manage to brick the device, don't worry, it got great capacitors and a fairly standard and documented line transformer for your next iteration.
