Hi all,
For my OxyHydrogen brazing electrolyser (pic), I need to condition the plates with a consistent 5-10A at 12V. The cheap eBay power supply I have, although fine for low power requirements, is not up to the job and can only muster 3-4V at 9A (reviews are pretty dire actually). I could use a car battery but there doesn't seem to be an easy way to fine-tune the current draw.
So I'm proposing I build a custom power supply as laid out in the pic. This uses the power transformer from an old microwave, removing the secondary winding and putting in about 15 turns of 1mm2 solid core wire. An off the shelf power rectifier and a couple of smoothing components.
My query is, firstly, are there any modifications I should make to this for effective operation? (The transformer will be inside a box and I will have a fuse)
Secondly, what is the red tube entity with the transformer? A choke, noise suppression, the capacitor they mention?
Thanks
Jules
