  • Power Supply for Electrolytic Process Industrial

    2020-7-10  Power supply required for electrolytic process is low voltage DC supply. For electro-deposition a power supply of 10 to 12 volts which can give 100 to 200 amperes is adequate. Using a suitable conversion such a supply can be obtained from ordinary 220 volts AC supply system. The conversion from AC to DC can be done by following methods:
