- In detail
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
Specifications
Given below are some primary specifications of electroplating rectifiers :
-
Input voltage between 380-440 Volts.
-
Output voltage is usually fixed rated maximum DC.
-
Output current is rated maximum direct current (DC).
-
Temperature rise is less than 45° C above ambient.
-
Efficiency depends on the voltage rating of rectifier.
Starting Circuitry
Rectifiers are designed for 2-3 phase and are available for operations within a wide range of voltage fluctuations. They are preferable to connect the input to the rectifier through a proper protective device, to provide positive protection to personal and the system, at the time 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.
