Electroplating Rectifier

Brief specification

MV Electricals make air and oil cooled plating rectifier's units are designed to provide D.C. Ripple free supply for Electroplates position processes. The sets are suitable for all plating applications particularly Nickel, Chromium, Hard Chromium, Anodizing of Aluminum, Gold, Brass, Copper, Lead Electro plating, Zinc, Cadmium, Tine, Plastics plating where high current with good regulation capacities to cover the widest applications from 10Amps to 10,000 Amps D.C. And output voltage 10 to 200v Dc

A.C. INPUT

Rectifiers are designed to work 230v & 415v 3Phase supply and suitable for an input range of 375v to 450v units of very small capacities, 10v to 200v DC output.

D.C. OUTPUT VOLTS & CURRENT

The DC output is continuously adjustable from zero to full rated value, from no load to full rated current, over the input range described. All 1Phase and 3pH units have low ripple of less than 5% and suitable for all kinds of metal finishing.

Major components of Rectifier

The units are assembled with high quality materials, and the components are manufactured to relevant specifications.

Main Rectifier Transformer

The transformers are of class "A" insulation and conform to IS 2026 in general .The laminations used are C.R.G.O silicon steel low loss type. The wound coils are impregnated with oven baked varnish.

I.P.T

For high currents units the transformers secondary is generally double wye. An I.P.T. wound with copper, is provided on its secondary, to extend the conduct period of windings and diodes.

Silicon Rectifiers

The rectifier is assembled by using silicon diodes mounted on heat sinks and connected in full wave circuits. Individual R.C. (Resister and Capacitor). Components are used for whole storage protection. The diode assembly is always selected to have at least 40% extra rating above the maximum output current.

Regulator

In order to facilitate voltage variation from zero onwards “VARI CONSTANT” variable auto transformers are used as independent units, or sometimes, accommodated in the transformers tank. Motorization is providing as an optical feature.

Protection & Metering

MCB/MCCB protection is providing on the input and 3 fuses are provided on the output of the “VARI CONSTANT” variable auto transformer. 3 pilot indicators are incorporated on the incoming side.96 x48 voltmeter and ammeter with suitable shunts are provided to read the output voltage and currents.

Optional Features

Following optional features can be provided

• Remote switching-on by using contactors and bimetal over load relays.
• Push button operation by motorization of the "VARI CONSTANT" variable auto transformer.
• Constant voltage or constant current features using electronic
• "VARI CONSTANT" auto transformer with zero start facility
• Timers, time totalizers, ampere hour meters, Etc..;

Vari Constant

Brief Specification

“VARICONSTANT" AUTO TRANSFORMER is a continuously variable voltage auto transformer, having a movable carbon tip, fixed to brush arm sliding on a silver plated Commutator. Rotation of the brush arm by either manual or motor drive, delivers an output voltage from zero or above line voltage
