Three phase input single phase output online UPS systems-Keda UPS-Guangdong China UPS & voltage stabilizer

Description

       KSD-series small and medium power three phase input single phase output UPS, single unit capacity from 6KVA to 60KVA. This series products adopt advanced digital design, the perfect combination of high-speed digital chips, ASIC's DDC control technology, advanced high-power IGBT and SCR devices, are large capacity, high reliability and superior performance intelligent UPS. This series product is the latest international hardware and the most advanced software combination.
Application:
To provide reliable power protection for the centralized server room, network management center and computer center.
Technical merits:
●Top technology application：
DDC (Direct Digital Control) / DSP (Digital Signal Processor) ASIC (Application Specified IC) IC/CPU  (microprocessor)
●100% digital technology
Adopting 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
●IGBT(Insulated Gate Bipolar Transistor)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.
● Fully meet the load jump from 0 to 100%:
The ability to provide instant full load requirements, but do not need to switch to bypass and keep output stable and reliable
● Large screen LCD monitor for convenient operation:
Running status, operational procedures, measurements value, troubleshooting information, image information, etc., are clear at a glance through the menu operation.
●Complete protection function:
With a variety of system protections, have protection alarm function to super-voltage, low voltage, over current, overload, short circuit, waveform distortion.
●Instantaneous waveform control method used to achieve the small output voltage distortion:
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, UPS can get rapid response to the load changes .
●Convenient communication:
RS232 communication port can truly realize multi-purpose communication and remote monitoring
●Intelligent battery management function:
UPS can set the battery charging current through internal software, automatically charge and discharge battery once every three months, at the same time carrying out 30mins average charging to the battery, so the battery maintain automatically, don’t need man operation, can prolong battery service life.
