CUBE SERIES

OverView

Power range: 300kVA/400kVA/500kVA

Work online, 3:3 phase, PF: 0.9

Features

High reliability

• Double conversion on-line technology. IGBT rectifier.
• Wide input voltage and frequency range, with a Power Walk In function, adapt to the harsh environment of the grid, reducing the impact on the generator, and the demand which is very useful for parallel system.
• A novel full digital DSP&FPGA control strategy, which is patent that can protect the ups unit when a single DSP or FPGA is failed.
• Modulation algorithm that is patent can reduce the area of the main circuit power, and the temperature rising inside the machine of the main power loop.
• A patent Short circuit modulation algorithm greatly reduces power loss in the short circuit cycle.

Energy-efficient

• Three-level rectifier and inverter, efficiency is up to 95.3%.
• Input PF larger than 0.99.
• THDi <3% (100% linear load), THDi <5% (50% non-linear load).

Parallel redundancy function

• Support parallel expanded operation; maximum is 4 units.
• LBS Function supported.
