Yes, ripple is AC leakage into what should be a pure DC current and can adversely affect plating if too high. Ripple is measured by AC/DC of the present setting and usually decreases as the rectifier is turned up. As a general rule, Max. AC ripple should not exceed 5%.

In explanation, is ripple defined by the minimum AC voltage over the rated output voltage only? Could the group enlighten me on the subject of minimizing ripple and how it affects plating? There's been much discussion about copper plating, and I would appreciate some information on this topic. Chemist, IUP, CU P.G.
