I. Brief Profile
With the on-line double conversion circuit design,the SPWM pulse width modulation design for the DC/AC inverter,the IGBT power modules and the output isolation transformer adopted,the UPS output is made into a frequency-& voltage -stabilized,purifying,non-interfered from the power grid fluctuations sine wave inver supply. In this way,such a series of interfence problems against the power sypply existing originally in the commercial power grid as the voltage fluctuations,frequency drift,waveform distortion,noise disturbance,lighting and thundr-strike are fully resolved through rectification and filtration into a DC power supply,so as to provide more comprehensive and prefect protection for the equipment of the users.sers.sers.
II.Features
High Reliability

The DSP digital control technology and perfect protection circuit are adopted, which is good in stability..
The power devices are designed with imported IGBT modules in original packing adopted, which are extremely strong in overload and impact resistance capability.
The dual conversion technology and the static electronic bypass technique are adopted, thus having truly realized zero switching time.
Extremely wide input voltage and frequency range, thus reducing the battery discharging time and extending the battery service life.
The advanced constant-current and constant-voltage automatic conversion charging technology and the float charging technology are adopted, thus maximizing the activation of the battery.
Provided with super-strong cold start function, which can be used for a cold startup at the full load under the condition that there is no commercial power supply available, so as to meet the emergency needs of the users.
The output is realized to be in precise zero-phase synchronization with the electric grid.
The UPS can work normally under a lacking phase state.
Highly Humanized
Friendly man-machine interface design:Using the Chinese LCD display + LED indication, keeping the UPS operation status seen at a glance and maintaining the communication at a zero distance between man and machine.
Easy maintenance:The modular design is adopted for interior, which is concise, smooth and clear in structure.
Multi-mode design
There are the ECO (energy-saving) power supply mode, the parallel redundancy, the dual-unit series-connected hot backup and the dual-power input power supply mode to be selected to fully meet the different needs of different users.
High Environment Protection
The overall machine uses the advanced anti-electromagnetic interference technology, which complies with the international standards, has very good electromagnetic compatibility and minimizes or even eliminates the electromagnetic interference caused to equipment.
The Input and output are equipped with the harmonic filter, which minimizes the harmonic interference of the UPS against the electric grid.
High Compatibility
The wide input range and frequency range of the commercial electricity reduces the requirement of the UPS for the commercial electricity inputted and can be compatible with any form of electricity, including such application occasions as the applicable industrial power and wind power.
Provided with the advanced software management function and the flexible network monitoring function, it is easy to realize the intelligent monitoring of the UPS, including the short-range point to point communication monitoring, the middle distance communication monitoring and the long-distance network monitoring and to realize the real-time monitoring of the UPS running status and the operating parameters. There are also such multiple functions provided as the automatic paging, E-mail sending, language functions and UPS remote switching machine. The operating systems supported include: Novell, Netware, MS-windows98, Windows2000, Unix, Linux, WindowsXP, WindowsNT and free BSD.
Fault Status Judgement Function
If the UPS is abnormal, the internal CPU will show the fault state on the Chinese LCD display, so as to understand the causes of the abnormal status before determining to carryout the corresponding processing.
