System Introduction

System capacity has 150KVA、250KVA、500KVA and etc models, power module is 25KVA, users can choose freely according to the load; 

System is for modular structure, consist of static switch module, monitoring module and N power module in parallel, module N + X redundancy, can proceed online expansion according to user requirements;

Monitor module, static switch module and power module can be online hot plug; system can be setted to 1/1, 1/3, 3/1 or 3/3 come into and outgoing line way as requirements; 

Adopt master-slave parallel, multi-stage distributed control technology, no operation bottleneck, reliable performance;

All power module share battery pack ,has perfect battery management function :battery has self-discharge function, automatic floating conversion function, temperature compensation, automatic flow function ;

Any power module has the balance of input, output, and charging power distribution function;

AC input adopt continuous current mode (CCM) to operate, reduce power interference (RFI/EMI);

Shape structure meet the requirements of the industry standard, equipment is small volume, light weight, can meet the ordinary building bearing requirements;

Optional input and output isolation transformer K values

Maintenance manual switch, C grade lightning protection module.

UPS can be used in parallel ,the maximum 4 pcs parallel to reach the expand demand.
