This UPS is developed as a high frequency on line modular UPS for medium and large data center, adopting fully digital control technology, fully guarantee power supply to operate reliably and stably; diversified option of modular power, accurately position user side requirements; flexible redundancy design greatly increase the system availability, user can realize expansion as demand, and modular structure greatly increase the convenience for maintenance.
Feature:
1, High reliability
Double conversion on line technology and Wide input voltage and frequency range make it adopt to the harsh environment of the grid and reduce The impact startup current on the generator .
2, Modular algorithm can reduce the area of the main circuit
Power and limits the temperature rising of the main circuit inside the UPS .
3, Energy saving
Adopting to high level topology design , efficiency is up to 96.3% , it can achieve to 99% under the mode Of ECO.
4, Parallel redundancy function
Support parallel expansion operation.
LBS Function supported.
Batteries can be shared by parallel units.
Parallel expansion up to 8 units of cabinet.
5, Battery charging
with the advance intelligent management of ABM mode , reduce the frequency of batteries maintenance ,
Greatly improve the battery efficiency and extends battery life .
The system can display the backup time of the battery calculated.
By discharge current and voltage.
Batteries are automatically tested at regular intervals .
6, N+X Parallel redundancy
N+X parallel redundant design, up to 8 units available ,makes the configuration more flexible .
It is easy to configure the parallel system just by connecting the cables and doing some proper settings.
7, Redundant control system
Each power module is equipped independent control .
System , and control itself independently according.
The sharing message , and the fault module separates.
From the system automatically.
8, Intelligent management
RS 232(USB) RS485 interface
SNMP card
Relay card
9, Clear LCD monitoring panel with on-screen instructions
10, Multi protection
Under/over voltage over load , short circuit ,over current , over bus voltage , over Temperature , fan failure ,battery fail and so on.
