Description

     KSS-series three phase low frequency online UPS, to meet the demand for high and medium power UPS, is researched and well designed UPS by the company's technology R & D center, organized dozens of professional and technical engineering staff, combining international cutting-edge three phase low frequency online UPS. This series UPS use advanced digital design, high-speed 16 digital chips, ASIC’s DDC control technology, advanced IGBT power device and SCR, is big capacity, high stability and reliability and excellent performance intelligent UPS.
Application：
This series three phase low frequency online UPS widely used in information center server room of important areas, large microcomputer-controlled automated production equipment, large precision medical equipment and precision electric control equipment.
Main technical merits:
● Adopting international advanced IGBT module excellent performance
    Good high speed switches high voltage and large current working characteristics; adopt voltage-    driven, only need small control power; working with high efficiency (low loss and low heat value), drive circuit miniaturization and high reliability.
● Application of international cutting-edge technology
    DDC(Direct Digital Control) /DSP（Digital Signal Processor）/ASIC（Application Specified IC）/CPU     （microprocessor）。
100% digital technology
Adopting three pieces high-speed micro-controller to achieve circuit control, parameter setting, the program running management, and advanced self-test and self-detection feature, which allows self-test and failure analysis to all the independent circuit connections on the circuit board . The sine wave voltage getting through digital transformation and new perfect running programs can meet your actual needs
●Fully meet the load jump from 0 to 100%:
In some cases, UPS must have the ability to provide instant full load, practice has proved that KSS series intelligent low frequency online UPS can fully meet this requirement, and do not need to switch to bypass and keep output stable and reliable
●Instantaneous waveform control method used to achieve the small output voltage distortion:
Three-phase independent transient wave control, achieving control transient overload degree of overload; current local loop control, the inverter adapt to the impact current when load starts up, and can high-speed control over-current caused by surge, feed forward control can make UPS get rapid response to the load changes .
● Highly secure and reliable design, complete protection function
With a variety of system protection, have protection alarm function to over voltage, lack voltage, over current, over load, short circuit and waveform distortion, so the machine failure rate is very low.
● Allow three phase 100% unbalance working
This series UPS adopts three phase independent modulation and full-bridge inverter technology, UPS can work normally when three phase load 100% unbalance, the technology is international advanced.● Improved intelligent functions
Through RS232 communication interface computer can realize UPS monitoring and management function, including AC power status and monitoring, recording, analyzing UPS working status, schedule power on/off UPS, monitoring UPS itself testing management, power interruption alarm, automatic power off system safely in very low battery status, send messages to users by mobile phone or email.
● Equipping SNMP adapter through RS232 communication interface through, constituting network remote management system to realize remote centralized monitoring and management, management software supports operating systems: Novell, Netwer, MS-windows95, MS-windows98, MS-windows2000, MS-windowsNT, MS- windowsXP, FreeBSD, Unix, Linux, etc.
●Big screen LCD monitoring operation interface
UPS with LED and LCD dual display system, when UPS works abnormally caused by the abnormal city power or city power failure ,UPS internal microcomputer CPU will display system fault state through the LED and LCD Dual display system, so that the user or technical managers can learn abnormal causes accurately in order to make the right deal timely.
