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 6th 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.


  • CNG331 series UPS using real online double transform structure. This architecture is currently the the best to solve the power structure. The framework can almost completely solve all the power problem, such as the power utility high and low voltage, voltage instantaneous fall, reduce oscillations, high-voltage pulsed, voltage fluctuation, surge voltage, harmonic distortion, clutter interference wave power supply problems. Provide continuous, stable and pure sine wave power for the load.
  • Adopt double DSP high speed digital signal processing chip collaborative central CPU microprocessor common to the system control, feedback, measuring, display, communication etc for all-round real-time processing, and make the system parameters keep the same when environment(temperature, humidity, noise, etc.)changes, even in the input signal distorted, can also provide accurate current, voltage , frequency and waveform output. This technology has powerful control functions, thus realizing the computer system’s comprehensive power management.
