(I'm a begineer in electrical stuff).
My wife needs a transformer for a leather electric creaser.
The transformers sold on the market are ridiculously overpriced (more than 250€). I don't understand why. Here are the specs of one of them :
1 LV output with 0V to 16V electronic controller. 3A 48VA.
What's so complicated/expensive in such a device ? How can I build one myself ?
