The battery charger offered by us is used to charge secondary cells once they get exhausted. DC source having voltage current characteristics to match the one specified by the battery manufactures is used fro charging these secondary cells. In order to produce the desired output for charging the batteries, the mains supply voltage is stepped down and rectified by using a bridge connected battery charger. We make use of one or more rotary switches to adjust the output within a limited range in small steps using a VARIPaC - continuously variable voltage auto transformer. Additionally, the DC output is electrically isolated form AC input.

Electroplating rectifier is a kind of electronic device which changes high voltage alternate current (A.C.) into low voltage direct current (D.C.). Electroplating rectifier is a very crucial component for any industry. For different industrial applications the electroplating rectifiers are available in a range starting from 1 Volt to 1000 Volts, to suit varying industrial requirements. Today these rectifiers are being used for various electro-chemical processes like Anodizing, Hydrogenation and more.
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.

y
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.
