4. Main features
4.1. Summary
This series UPS is a kind of 3-phase input/ 3-phase output-out high frequency online UPS.
The 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.
4.2. Functions and Features
3 Phase In/3 Phase Out UPS
It is 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 Digital Signal Processor (DSP); hence it increases reliability,
performance, self-protection, self-diagnostics and many more.
Battery is Configurable
The battery voltage of this series UPS is configured to 20 blocks.
Charging Current is configurable
Through the user interface, the user may set the capacity of the batteries as well as
reasonable charging current as well as maximum charging current. Constant voltage mode,
constant current mode or floating mode can be switched automatically and smoothly.
Intelligent Charging Method
The L series UPS adopts advanced three-stage charging methods
•
1st stage: high current constant current charging to guarantee to charge 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.
