250kVA N+X Parallel Redundancy Pure Sine Wave Online Modular UPS Power Supply

System I ntroduction

System capacity has 1 50 KVA,2 50 KVA,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 set t ed to 1/1, 1/3, 3/1 or 3/3 come into and outgoing line way as requ i rements ;  
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 fu n ction ;
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);
S hape 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
M aintenance manual switch, C grade lightning protection module .
UPS can be used in parallel ,the maximum 4 pcs parallel to reach the expand demand.
