3 Phase 20A Rectifier Charger with RS485

Preface

Intelligent high-frequency switch power supply modules are specially developed to meet the demands of modern DC system,The charger rectifiers are designed with world leading patent technology “resonant voltage type type soft switching power supply technology”.they feature high efficiency and stability,intelligent control,small size and light weight.

The products listed in this manual are the fifth generation,which are of higher working frequency,smaller size and lighter weight compared with past products.

Rated output voltage 220V and 110V

Rs-485 inerface,easy to work with automation system

Applicable for electric and relevant indusries

System performance

Modular design, N+1 hot backup, smooth expansion;

Intelligent design, achieve the following functions automatically via serial communication: module switch on/off; 

charging mode converting, output voltage setting, output current setting, SYNC switch over and etc.

With standard RS-485 interface, easy to work with automation system, “4-remotes” function; Hot swappable.
