Technology advantages

1.1 GP switching power supply uses digital control, compared with traditional analog control mode, digital control has advantages such as

(1) high reliability

(2) simple circuit

(3) less components

(4) high control accuracy

(5) easy to realize the complex and advanced control algorithm.

(6) Don’t like analog control, the digital controller’s control performance will not change because of ambient temperature change, power supply reliability and performance will not reduce because of long time using.

1.2 GP switching power supply adopts modular design concept, for high current applications, uses standard modular parallel solution, through CAN bus for digital current equalization, uneven current degree between modules is less than 1%; using intelligent parallel control mode, when one module is out of operation due to failure, other modules will share the output current of failed module automatically, so as to ensure uninterrupted operation of the whole power supply.

1.3 Human-Machine Interface adopts using visual touch screen interface, real-time display of power output voltage, current, power and other parameters, can easily achieve a variety of process curve setting, save output parameters and display waveform real-time. Convenient to adjust power supply control parameters, output voltage, current calibration coefficient etc.

1.4 Full Safety Protections to protect rectifier, please check below tables, and you can set alarm or alarm+stop rectifier in case of specific protections:

GERE has below measures to ensure quality:

1. "Quality First” concept in our whole company

2. Well-trained employees in every position, pursue high quality work outcome

3. Reliable design based on strong technical ability and more than 20 years experience in power supply industry, DSP digital control

4. Reliable material and components, USA TI DSP chip, Film capacitor used, and so on

5. Quality ensured assembly & wiring, standardized craftwork

6. Quality control in each process, IQC, IPQC, OQC

About Quality:

Compared with other Chinese companies, even though some parts are also imported brands, such as Infineon, Fuji, in our opinion, there are many factors to affect quality:

(1) We use all reliable materials and components other than above parts, including cables, wires, screws etc. everything. 

(2) Experience in the filed, we have more than 20 years experience, and produced many high power IGBT rectifiers.

(3) Technical ability:

·   First important is control technology, which is most important, because control is core of the whole rectifier, if controller is broken, the rectifier can't be used, like you encountered the problem before. 

·  Second, module parallel connection technology, we use CANBUS for digital current equalization, uneven current degree between modules is less than 1%. Intelligent parallel control technology, when one module is out of operation, others could continue working. 

·   Thirdly, we use Film Capacitor which has high reliability and long lifespan. 

·   We use touch panel for HMI, easy monitor and setting. 

(4) Internal quality control management, each step we have strict quality control. 

(5) Assembly and wiring craft work

(6) Production ability and production quality control
