Electroplating is technique accomplished through electro deposition process. The process involves producing a coating, mostly metallic, on a surface by the action of electric current. Electroplating rectifiers are single phase or three phase devices on the basis of their rating. Generally, 8V, 12V, 16V, 20V, 24V rectifiers are used in industries having current rating of 500 Amp and above.
Starting Circuitry
Rectifiers are designed for 2- 3 phase and are available for operations between different voltage covering a wide range of voltage fluctuations. It is advised to connect the input to the rectifier through a proper protective device, to provide positive protection to personnel and the system, in the event of maintenance or in case a fault occurs.
DC Output Control
The function of the variable output controls is to control the voltage or current or its operating range by varying input voltage to the main transformer primary. The DC output voltage variation is achieved steplessly 0-100% by means of an on load roller type power's make voltage regulator.
Applications
Electroplating rectifiers are widely used in metal finishing industries for:
- Galvanizing
- Copper plating
