Summary of Advantages of Chunshu IGBT rectifier

High efficiency, high reliability, high intelligence, long lifespan

High Safety, EMC performance, passed CE testing

1) DSP digital controller, approved software copyright

Benefits of digital control:

l Fast responding speed, high control accuracy and high stability

l Programmable, flexibly controlled, don't need to change hardware to realize control change only changing program of DSP chip

l Smart communication expansion and network formation. Profibus, CANBUS, RS485 communication optional.

l No parameter drift like analog circuit. Resistance and capacitor in analog circuit will change value after long time.

l Good load adaptability.

l System parameter identification and fault pre-diagnosis.

l Realization of various algorithms.

2) Touch screen, easy to operate, display and save history record

Strong functions: save history data, inquire fault type, save fault record, set protection value, set output value easily, inquire water pressure, water temperature, set local control or remote control, choose constant current or constant voltage, inquire output waveform etc. functions

 

3) Modular design, have high reliability

Replace European KRAFT, have high reliability, when one module is broken, other modules could continue working. Module is easy to replace and maintenance.

4) Water cooled high frequency transformer, high efficiency, authorized patent

l Use non-crystalline material magnetic core which gets higher efficiency than ferrite core, the supplier is AT&M, which is the best one in China, listed in stock market.

l Water connection is reliable.

 

5) Phase shift full bridge soft switching technology, get higher efficiency than hard switching technology.

6) Redundancy ability, high reliability

7) Good craftwork, get high reliability

8) Copper bus bar, get high efficiency

l Use copper bus bar inside rectifier while others use wires for inside connection.

l Copper bus bar is nickel plated and anti-corrosion

l Have low current density to have less power loss and get high efficiency.

9)Cabinet is 1.5-2mm thick steel sheet, strong nine bending Powder painted, anti-corrosion. Other competitor rectifier cabinet is welded.

10)Stainless steel water pipe, pipe connector is well connected to avoid water leakage.

11) Use water cooling aluminum plate for cooling inside rectifier

12) Use EACO capacitor, lifespan for 20 years.
