Digital DSP control. 

     Customer Benefits of 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

•  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

(2) Modular structure, compact size, light weight. 

Customer Benefits of modular solution

GERE 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, optimizing floor 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.

3) Touch panel HMI, will show protection type automatically in case of any protection. 

Customer Benefits of touch panel HMI

 

GERE 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 up to 20 process curves and up to 20 step process parameters

• Set constant voltage or current

• Record history running data

• Record history protections

• Programmable for custom design

• Different languages available
