I have been anodizing at my job for five years. The parts were mostly for use on optical tables, bead balsted and deep black dye.
Because the parts were small, sometimes .5 inch diameter and .09375 inches thick, voltage and current were not really a concern, ramp up to 13.5 volts, and monitor the current, time for 30 minutes. I have always had good results. I used a 4000ml beaker for the bath and placed it in a bowl filled with water, wrapped cheese cloth around the beaker and used a fan to blow air across it. Cheap, but it worked.
I now want to set up a system at home with higher capacity. Being and electronic technician, I am looking to build my own power supply. I want the nice features like automated ramping, alarm for voltage/current change and timing.
My question is, how big of a power supply do I need for type II? I have read the various messages and have looked at the 720 rule, etc. I guess I need to know the highest voltage that will be needed and I will have the transformer made to a good current level. I see a maximum of 1500va, lots of power! At present, I am looking at a 2 square foot maximum as I am leary of the amount of hydrogen sulfide gas that will be produced.
