20000A 12V Copper Electrowinning Rectifier

Full Specifications:

20000A 12V  power supply For hard chrome plating

This rectifier adopts high frequency IGBT as semiconductor component and PWM modulation technology. It is modular structure design, easy to expand output current capacity, several rectifier modules could be connected in parallel and mounted in stack up to 20 modules to make more current single rectifier. has independent power modules, each module could output independently or output in parallel connection.

 

Working principle

Three phase AC input is converted to DC through rectification and filter, then DC voltage is transformed to DC output through phase shift full bridge PWM DC/DC converter.

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.
