Power supply for anodising?

[Zeeflyboy]

alternatively, this one is a bit cheaper...

15v should be sufficient? Allows up to 6amps/sqft according to the 720 calcs.... any thoughts on whether it is desirable to be able to do more than that?

Something like what you've linked looks good.

Alternatively, have a search over on the EEVblog forum, as I'm sure I've read some posts on there about constant current supplies (I've not been on there for a good while, so I may be getting confused with somewhere else!).
I'm sure there's plenty constant current schematics around, but when you get to that amount of current, they have to be well designed to avoid releasing magic smoke.

Thanks for that, I'll have a look over there but since you say one of those I linked is suitable I will probably go for a proper retail unit rather than try building my own.

Cheers

With a suitable transformer - or batteries if you want.

Housed in a case, if you want ...

I was in that doubt before some time.

Maas HCS 3400 1-15V, 0-40A Bench Power Supply was the one i bought and i believe is a best heavy duty budget one that could cover quite big parts like alloy wheels and so on. Its well tested and serves for the purpose, German quality control , its Chinese but bit better than no name crap.

The one Jonathan linked to is 0-50V yours is 0-15v but it does need an external supply

Anodizing needs Amps not Voltage . Its perfect for the purpose, i wouldn't have recommended or bought it if it was the wrong one...

Now if he was anodizing Titanium or messing with plating, a better supply will be the 3602, which is 0-30VDc 0-30A. And yes, thats maybe the best Lab PSu to have at home for multipurpose, but its quite more expensive.

There are other cheaper possibilities:
