Features of the Modular Online UPS
EA660 modular UPS has the characteristics that it has the independent power and control sections. Each module is an independent UPS. It is composed of multiple UPS parallel connected (N+X format). It's simple for system expansion and can be maximally expanded to200kva. It provides load with higher (N+1 to N+X) levels of protection.

Easy Expansion
When there is a higher requirement on load, users may need to have a new UPS with higher capacity. But for EA600 modular online UPSs, there is only a need for adding the required numbers of modules for expansion.
EA600 modular online UPS can be expanded online from 6kva to 200kva. It saves customer's costs for initial equipment purchasing and future expansion.

Hot Swappable
Hot Swappable UPS modules can to be added or removed on line without equipment 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 and 3 phase out, 3 phase in and 1 phase out, single phase in and out, single phase in and 3 phase out.

EA660 Modular UPS system
Each module in the modular online UPS can run independently, and supports hot plugging. The UPS fans are controlled by a stepless speed adjustment system, and can automatically change speed according to temperature and load conditions. The modular online UPS features high system efficiency, low energy consumption, and has no pollution to mains power.

UPS Modules
On-line dual conversion design assures the output quality.
Every UPS module has independent digital and intelligent control system, and also has independent charging system.
External output isolation transformer is optional.
On-line removable grid panel guarder and filter for easy cleaning.
Closed air duct design provides high cooling efficiency and low temperature rising for components.

Static Transfer Switches
Static transfer switch design allows the modular online UPS to achieve rapid transfer. Meanwhile, the UPS has high reliability, high overload capability of 1000%, and is available with functions like self-diagnosis, interlock, and protection, etc. It supports on-line replacement, which makes UPS replacement and maintenance simple and convenient.
In addition, the modular online UPS is energy saving. Most traditional UPSs have an efficiency of 90%, while our modular UPSs have high efficiency of 96%. Our products have low heat generation and less energy consumption.

Green and Clear Power
The level of harmonic pollution of EA660 modular online UPS is very low, due to the low input current THD <5% and the near to one input power factor. This reduces pollution to mains power supply and power loss.
