2. Aluminum anodizing pulse rectifier Product Description
Over the past 20 years, Green Powerhas continuously developed its technology of rectifier for anodizing and has recognized internationally as high quality manufacturer in the field of Alumnium Anodising, the core technology includingpulse rectifier technology, DSP digital control technology, modular parallel connection technology and intelligent touch panel controller technology.
Pulse rectifier's modular, highfrequency switch-mode technology is applied for Aluminum anodizing process. Switch power supply technology offers many advantages over conventional rectifiers based on thyristor technology. As a consequence of the proven, reliable, compact technology, switch mode systems are excellently suitable for the demanding anodizing area.
Normally for decorative anodic oxidation of aluminum 24v power supply is used, typical types inculde 1500A 24V, 2000A 24V, 4000A 24V, 5000A 24V, 6000A 24V, 10000A 24V.


3. Aluminum anodizing pulse rectifier Main Features

4. Customer Benefitsof pulse rectifier
Power saving
Through IGBT PWM technology, rectifier conversion efficiency is much higher than conventional SCR rectifier, thus saving power of user dramatically.

Better quality
The oxide quality is better by using pulse rectifierthan conventional SCR rectifier with equalaverage current This is proved by several on-site actual testing.

Time saving
Using pulse rectifiers save anodizing time 20-25% approx. This is because using a pulsating waveform carry out anodizing at higher average current in comparison with conventional direct current.

5. Customer Benefitsof modular solution 

Green Power developed module based IGBT pulse rectifiers, which have the following advantages:

● Rectifier won't break down: in case of one module failed, the rectifier continue working with reduced power.

● Less downtime and easy recovering:plug-in structure, replace module directly, downtime is shorten to minimum, this reduces potential high cost of your plant stop and increase your plant's availability.

● Current expansion available:thanks to the modular design and supporting parallel connection, if you need more power, you only need to add more modules.

● Reduce current rating to save power: if you don't need all modules working, you can switch off some modules, rectifier can work at lower rating.

● Less floor space occupied: the rectifiers can be built on top of each other, making them easy to fit into your plant's design, optimizingfloor space.

● Easy to install and maintain: each rectifier consists of up to ten modules and naturally two or more stacks can be connected to allow higher currents (40kA) and voltages (200V DC).

● Separate output or parallel running output available: you can let the rectifier module separate output to connect to more tanks, or parallel connecting to get higher current for one tank.

6. Customer Benefitsof digital micro controller

● Consistent high stability in long time, not like analog control resistance and capacitor may change value causing control reliability reduce after some time.

● High control accuracy(up to 1/1000 of max current or voltage)

● Protection self diagnosis and alarm protection type automatically on touch panel, easy for troubleshooting

● Timer counting, stop running when times up

● AmpereHour counting


● You can preset up to 20 process curves, once you choose one process curve, the rectifiers auto run as per preset process curve.

● One process curve, you can set up to 20 steps (you define V or A value and step process time), auto running based

● Support soft start and soft stop time setting

● Fast responding speed

● Programmable, only reprogramming to DSP, don't need to change hardware like analog control

● Smart communication with PLC, RS485, Profibus, Profinet communication optional, 4-20mA/0-10V signal

● Adapt to different loads

7. Customer Benefitsof touch panel HMI
Green Power touch panel solution will help you full control of the rectifiers and your business, using one touch panel realize all controls and displays, say goodbye to separate control systems. You can control up to 10 rectifiers in one touch panel, you can control up to 20 different process in one touch panel, you can put touch panel on the rectifiers for local control or put away distance for remote monitoring.

● Installed on rectifier or away distance for remote monitoring

● Up to 10 rectifiers share 1 touch panel for saving cost and centralized control and display


● Full information of the rectifier running status on touch panel

● All operations on touch panel

● Notify operators protection type automatically for easy troubleshooting

● Set protection parameters: protection value, alarm or alarm+rectifier stop mode for difference protection separately

● Set upto 20 process curves and up to 20 step process parameters

● Set constant voltage or current

● Record history running data

● Record history protections

● Programmablefor custom design

● Different language available

8. Customer Benefitsof high quality
Green Power provide reliable quality to ensure the customer's process smooth, continuous running, reduce the extra loss because of process break-down, repair, repurchase etc.
All materials and components we use are high quality, considering for the rectifier high reliability.
