Good product, can draw nice arc's, see pic1. The driverboard mentione 12-36V input, but I would not go above 24V, at approx 30V, the fb got a little fire, see pic 2, still working fine though.

Deliveres several kV of voltage ... and you can pull quite some sparks. With the dedicated primary winding on the Flyback Transformer there is no need to tweak around with the pinning of the transformer to find the best point of operation. Everything just works. The secondary winding of the transformer has a quite high resistance (common for this kind of transformers) so when pulling too much current it gets quite hot. So such an item is considered for short ED usage or for operation with some sort of current limiting use case (i.e. Ozone Generator with ceramic or glass isolator ....)

good solid construction. zvs stays cool as cucumber. came well packaged

Great value for money, got at least 4cm arcs with 10 volt 5 amp supply, I have a 30 volt 12 amp PSU on route and can't wait to see what arcs can be made then ! The unit is of high quality and when even making large arcs the driver board remains cool ... All in all recommend to anyone interesting in high voltage!

Excellent! I loved and thank you.

Consistently drew an arc around 3 cm on 12V 6A supply. Note that the PSU was current limiting though a lot of the time. On a ladder starting at about 20 mm it gets up to about 35mm before it breaks and starts again at the bottom. Found it necessary to bring the wires together from below then open the ladder above.
