ups power, modular ups manufacturer

EA660 is a modular parallel redundant UPS system. It has the independent power and control sections. Modular design ensures flexible options for expansion. redundant UPS technology allow users to scale their power capacity and provide load with N+1 to N+X levels of protection. Great power density ensures a small footprint and low heat dissipation. Rich management and communication functions ensures a user- and environment-friendly system.
 
Ideal Application 
This modular ups is applicable to all kinds of fields such as financial, tele-communication, government, manufacturing,Transportation, energy resource industries. Bring perfect security to customers systerm. 
 
Features & Benefits 
EA660 modular ups has the characteristics that it has the independent power and control sections. Each module is an dependent UPS. It adopts the centralized multiple parallel N+X format. It's simple for system expansion with little fault points. This modular ups provides load with N+1 to N+X levels of protection. The maximum can be expanded to 200kva.
 
Easy Expansion 
With the upgrade of customers' load requirement the original designed UPS may not be able to meet the demand. According to the traditional UPS system, we must replace with a new and higher capacity UPS system for customers. But for EA600 modular UPS there is no need to replace the whole UPS, but only adding the required number of modules for expansion. EA660's modular UPS can be expanded on line from 6kva to 200kva. it saves customer's costs for initial equipment purchasing and future expansion.
 
Hot Swappable 
Hot Swappable modules can to be added or removed on line without shutdown. It ensures online maintenance for the redundant systems, and make UPS expansion and redundant easy. There is no need for senior technical personnel to perform the job. It is safe and convenient.
 
Multi-setting
According to input power condition, user can set up the UPS configuration with 4 kinds of working model (3 phase in & 3phase out, 3 phase in & 1 phase out, single phase in & out, single phase in & 3 phase out )
 
EA660 Modular UPS system
Self-adapted synchronized poles' distrubtion parallel control Modules control seperately, run parallel Different capacity for defferend need, N+X redundance Every module can run independly , support hot plug-in Fans controlled with Stepless Speed Adjustment, adjust the speed automaticaly in accordence with temperature and load High system efficiency, Low energy consumption, No pollution Avoid single spot faulty, prompt the reliability and practicability
 
UPS modules
On-line dual conversion design, assure the output quality Every module has digital and intelligent control separately Every module has independent charging system External output isolation transformer for option On-line removable grid panel guarder and filter for cleaning Closed air duct design, high cooling efficiency , low temperature rising components
 
Static Switches Static
Switch module for standard mode UPS Work in SCR and AC contactor paralleled High reliability, high overload taking ability: 1000%, 1 second 0ms transfer time Function of self-diagnosis, interlock, protection etc Support on-line replacement Energy-saving Compared with traditional UPS, whose efficiency is less than 90%, about 10% is going to be wasted. EA660 inverter efficiency is more than 96%. It is designed for low heat emission, less energy consumption.
 
Green and clear power
The leve of hormonic pollution of EA660 is very low, due to the low input current THD <5% and the near to one input power factor. This reduces more Mains pollution and power loss than equivalent traditional UPS.
