Electroplating Rectifier Introduction


Chrome-plating-factory.jpg

The electroplating rectifiers are widely applied for metal and plastic plating, rack plating, barrel plating and continuous plating, plating types include: 

   -Chrome plating and hard chrome plating;

   -Nickel plating;

   -Copper plating;

   -Zinc plating;

   -Galvanizing;

   -Tin plating;

   -Others

We provide high efficiency, high accuracy, high reliability, high frequency IGBT based rectifier for electroplating industry. 

Modular based, support convenient current expansion through modules parallel connection, compact size.

Provide multiple remote control communication options.

Advantages of Green Power Electroplating Rectifiers

For electroplating industry, because of low output DC voltage(normally 12V, 15V, 18V), we recommend using Green Power IGBT high frequency switch mode power supply (not SCR or diode rectifier) because of below reasons:


1. Same level of high reliablity as SCR/diode rectifier, support 100% output 24 hours continuous running, no need extra capacity. 


2. IGBT plating rectifiers have higher efficiency, for 12V rectifier, typical efficiency is higher than 88%, that means power saving for you, and more years running, saving more. 


Below is a power saving calculation for 1000A 15V rectifier comparison, considering running hours is 6300 hours per year.

3. Compact size, saving a lot of space for you.

4. Modular structure, high reliability, not like SCR rectifier, IGBT rectifiers' one module break-down won't affect other modules running, rectifier don't stop, don’t need to stop plating line.

5. High power factor in full range, higher than 0.93 at rated output, no need extra reactive power compensation facility, avoid fined by government because of power factor, saving cost. Support modules connection in parallel to have higher current capacity. 


6. Not like SCR rectifier, the ripple won't be higher when output is not at rated value, not affecting plating quality because of ripple. 


7. Pulse output, needs less plating time than SCR rectifier. 


8. Less affected by input power fluctuation because of buffer function, support 100% output. No need extra capacity, such as if you need 800A output, you don't need to buy 1000A, 800A rating is enough.
