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.
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)
Excellent Electrical Performance:
Online double transform structure, double DSP control technology.
Super output overload capacity:
110% rated load for one hour
125% rated load for ten minutes
150% rated load for one minute
With a strong anti-step of load and short circuit output capacity:
UPS power supply operation in the worst working conditions encountered by the user in the UPS
Output load 100℃ rated load for the input or the removal operation. The most situation is that the UPS output is short circuit.
Sinc the CONSNANT UPS, configure a unique design of the output current limiting circuit. Even if the user inadventently caused by the output short-circuit fault, it’s UPS inverter will not be damaged. Typical UPS output capacity of short circuit’
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:
For the three phase in/three phase out UPS, even with a peak in the ratio(crest ratio) is 3:1 in the non-linear loads like computers, they can;t reduce the rated output power conditions and provide users with distortion less than 35% high-quality sine wave power. Moreover, as the machine is 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:
Controlled circuit of auxiliary power for each provide reliable, stable power protection so that ensure all the control circuit to work properly. To ensure the normal operation of UPS systems play a key role. CNG331 series UPS’s auxiliary power adopt 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:
Battery and UPS by connecting an external battery switch, the battery switch is a “three state” DC switch that can be manually closed, and has a control circuit controlled by the UPS electronic tripping device. Effectively reducing the past due to battery leakage or short circuit caused the fire risk for the safe operation of the engine room has provided a guarantee. Battery switch has the following characteristics:
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%:
Overview of large UPS equipment, efficiency, impact significantly on energy costs that percentage of minor differences can save considerable operating costs. Our design team from start improve efficiency and make a lot of effort. Especially for the actaul operation of the load rate (Example:50% of the load operation, etc) were carefully considered.
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:
As well-known, the rectifier filtering load( such as computer, communication equipment, appliances or general UPS ) was introduced to power grid largely and the power grid will be polluted, higher harmonic current that caused by pollution through the whole power supply system. Over current that flow past mid line and motor load are heat abnormally. To deal with those problems, we provide some solutions to eliminate the harmonic pollution so that ensure quality of power reach the standard of Green power: CNG331 series are adopting optional input filter and 12 pulses rectifier filter, the solution improves the input power factor to above 0.95, reduce the input harmonic current to 10%.
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
