I have been pondering whether to set myself up with anodizing equipment. The most expensive part would be the power rectifier. It occurred to me that the rectifier does much the same job as an LED driver, it’s a constant current source while the voltage floats. I considered trying a driver connected to my PSU but someone pointed out there may not be enough load to stop the driver from frying.
I have tried to search around a bit but there’s not lots of info and what I do find is not highly accurate. For example I’ve read some people use a (car) battery charger as a current source. In other places I read that the charger’s current is not smooth or constant enough to properly suit this application. I have a (20amp) hobby charger that runs from the PSU. Would that be any better than a car battery charger?
Failing that, can I use something like this? Or can I get some other circuit board to run off the PSU? BTW the PSU is 11-18v (variable) up to 500w (I expect that claim is peak and not intended for continuous use).
I’m hoping some electronics guru here (I’m sure there must be some ) might point me in the right direction.
