either you take 220V AC and you need a transformer (there are also these small power supplies, very used in cars / camping cars on the cigarette lighter).
Except you are wrong Remundo: a REAL UVc tube cannot work directly under 12V DC ... it is necessary to ionize under high voltage / frequency the gas in the tube ... I measured 37 Hz on the circuit ...
Otherwise they are fake UV tubes just black "light" like UV led tapes (see what Guy had posted above) .... nothing to do with UVc disinfection so ...
I don't really want to burden myself with a 12V-230AC inverter in my assembly .... I have one of 100W lying around somewhere but that would complicate my assembly ... and would lower the overall yield. ..if I can consume to avoid consuming 20W instead of 5W that would suit me ...
So if I can supply this board with 12V somewhere I am interested!
So sorry but my problem of the day is with object!
