Main features
3.1. Summary
This series UPS is a 3-phase input/ 3-phase output high frequency online UPS.
This UPS can solve most of the power supply problems, such as blackout, over-voltage,
under-voltage, voltage sudden drop, oscillating of decreasing extent, high voltage pulse,
voltage fluctuation, surge, inrush current, harmonic distortion (THD), noise interference,
frequency fluctuation, etc.
This UPS can be applied to different applications from computer device, automatic
equipment, communication system to industry equipment.
3.2. Functions and Features
3 Phase In/3 Phase Out UPS
This UPS is a 3 Phase In/3 Phase Out high-density UPS system, of which input current is kept
in balance. No unbalance problem might occur.
Digital Control
This series UPS is controlled by its Digital Signal Processor (DSP)providing increased
reliability, optimized performance, self-protection, self-diagnostics and many more.
Battery is Configurable
The battery pack of this series UPS is configured to 20 blocks.
Charging Current is configurable
Through the UPS user interface, the user may set the capacity of the batteries as well as
reasonable charging currentand maximum charging current. Constant voltage mode,
constant current mode, or floating are easily switchable.
Intelligent Charging Method
The series UPS adopts advanced three-stage charging method:
1st stage: High Current Constant Current charging to guarantee charging back to 90%.
2nd-stage: Constant Voltage in order to vitalize battery and make sure batteries are fully
charged.
3rd stage: Floating mode.
This 3-stage charging method will extend life of the batteries and guarantee fast charging.
