This 12V 100A reversing power supply with local control panel is developed for electrochemical applications requiring reliable polarity change operation, including reverse plating, surface treatment, and laboratory electrolysis processes. The built-in control interface allows operators to conveniently set and adjust output parameters and reversing cycles directly on the unit without an external controller. Featuring 220V single-phase input, the power supply provides stable DC output, accurate current regulation, and flexible reverse timing control. It can be customized with different output ratings, reversing modes, display functions, and communication options to fit specific process requirements.
