Electroplating Rectifiers :
These are low voltage high current DC Power supplies, mostly working on 3 phase AC input. In exceptional cases, input can be single phase also.

Specifications :
The broad specifications are :

• Input: 415 V3 phase 50 Hz AC+/-10% (240 V1 phase in exceptional cases)
• Output: Variable steplessly or in small steps from zero to any value upto 50 V DC
• Capacity: Upto 10,000 Amps.

Ripple Content :
This is an important characteristic for many electro-chemical processes. High ripple content adversely affects the performance of the process. Ripple is an AC component in DC output which is around 48% in units working on 1 phase supply and 5% for units working on 3 phase supply. Using a proper circuit configuration ripple can be reduced to 1% without using any filters to reduce the ripple further.
Constructions :
These units are made in oil cooled construction to avoid the corrosion of components due to the acidic fumes normaly present in electro chemical process plants.

However, for special applications, these can be made in air cooled/forced air cooled construction, upto a certain capacity.

Smaller capacity units are single unit type. While large capacity units are made in 2 to 3 sections for ease of manufacturing and transportation which are interconnected at site.

These are meant for indoor use only.

Salient Features :

• Output isolated from input.
• Diodes de-rated adequately and provided with R.C. Protective network.
• Output is monitored by Ammeter and Voltmeter.
