Efficient-energy- saving+ Environmental-protection+innovation:

CNG331 series UPS for China’s top product, nominal capacity from 120KVA to 800KVA, dad application in key equipment for the power system protection, could provide high quality power, with high level of availability and scalability, and invest iminimize Total Cost of the Ownership(YCO)

Application:

Application mainly used in large IDC rooms, banks/securities settlement center, communication network management center, semi-production lines and large automation production with its control system. According to the special need of users was improved, used in large sports venues, conference room, theather, highway and railway tunnels metal halide lamp lighting system.

Key Features:

• Use advanced 6^th generation DSP and full digital control technologies to realize higher system stability.
• Output power factor is 0.9, carrying capacity than conventional UPS with 10% above, as users reduce investment cost.
• Advanced distributed activeparallel technology can realize parallel operation of 6 pieces UPS units without the need of centralized bypass cabinet.
• 6-inch extra LCD that can display 12 language(Chinese, English, Russian, Spanish, French and so on.)
• Extra wide input voltage and frequency range make it adapt to serve powewr ggrid environment.
• Intelligent battery management maintains battery automatically to prolong the battery life.
• Standard input/output filter improves the system EMC performance.
• Extra strong capability to withstand output overload and and short circuit, ensuring the system stability and system safety under extreme conditions.
• Layered independently-sealed ventilation channel and re-dundant fan, circuit boards with protective paints and a dust filter embedded make it highly efficient to disspate heat and protect the product effectively under severe environment.

Excellent Electrical Performance:Online double transform structure, double DSP control technology

Super output overload capacity:"inversion state priority”thinking.

The typical overload capacity of UPS as follow:

•  Three phase UPS working:

110% rated load for one hour

125% rated load for ten minutes

150% rated load for one minute

•  Single phase UPS working: 200% arted load for 30 seconds
•  When the user overload no more than the above range, UPS will continue to maintain the load by the inverter power supply status.(Note: output power factor is 0.9)

With a strong anti-step of load and short circuit output capacity:

Three phase work, the output current is limited to 160% nominal output current, 5 seconds.

Single-phase operation, the output current is limited to 290% nominal output current, 5 second.

Superior ability with three phase unbalanced load:equipped with adaptive equilinrium adjustment circuit, when followed 100℃ unbalanced load(one-phase no-load, two phase full load, they can ensure that the three-phase phase voltage difference is less that 2C , and phase difference between the 120º±1º ranges. This indicator was higher than similar products of other companies.

N+X redundant design of auxiliary power supply:

CNG331 series UPS’s auxiliary power adopt Controlled circuit of auxiliary power for each provide reliable, stable power protection; 1+1 redundancy design, when one of the auxiliary power failure, can be continued by another auxiliary power supply. UPS continue to operate normally, while the LCD screen displays this warning message.

Unique battery protection:

1. Battery is isolation, safe and reliable;

2. Short circuit protection

3. In case of battery voltage causes the inverter lock, then switch off automatically to avoid battery discharge damage

4. Fitted with a remote emergency stop button, emergency stop button can be used remotely disconnect the switch; misuse protection

Easy maintenance of structure design:

Using user-friendly control panel modular inline graphic design, to ensure reliable connection between the plug plates, the connection is configurated with a connector locking mechanical”locking” device. Users simply open the cabinet door that can be observed a glance at the control panel of the UPS “self diagnosis” status monitor the work of the state. As a result, users can quickly access to nearly 70-90 species of fault alarm indication, and improve the maintainability of this UPS.

Efficiency, energy-saving, environmental protection design, efficiency of the machine is up to 94%:

Clean stable output waveform:

Output voltage curve 1% change in the sine envelope line digital pulse-width modulation with free frequency 250%, 200, 120%, 100%. roteting UPS SCR-based UPS Translator-based UPS CNG331 UPS Power Demands Non-liner load 100% . To ensure the non-linear load voltage voltage distortion ≤3% the min capacity of kinds of UPS need

High input power factor level, harmonic distortion cancellation: save cost of energy consumption, reduce power pollution

Core of high available configuration great parallel output features:

■There are frequency busbar and current busbar in parallel control system, they can control each UPS phase relation and flow equalize output feature. So the system not only ensure each UPS located in general UPS power supply can share load current, but also it can reduce the circulation maybe happened in parallel system to zero.

■ Moreover, because of sensitive circulation survey, it can survey the operative mode of UPS power supply system constantly and with high reliability (MTBF reach to 1 million hours), it is the top level in the similar type
