    Low Frequency Online UPS Low Frequency Strar Series LF33 10K-120K(3Ph in/3Ph out)

    Key Features

    ● Use advanced 6th generation DSP and full digital control technologies to realize higher system stability.
    ● Output power factor is 0.9, carrying capacity than conventional UPS with 10% above, as users reduce investment cost.
    ● Advanced distributed active parallel technology can realize parallel operation of 6PCS UPS units without the need of centralized bypass cabinet.
    ● 6-inch extra large LCD that can display 12 language (Chinese ,English,Russian,Spanish,French and so on).
    ● Extra wide input voltage and frequency range make it adapt to severe power grid environment.
    ● Intelligent battery management maintains battery automatically to prolong the battery life.
    ● Standard input/output filter improves the system EMC performance.
    ● Extra strong capability to withstand output overload and short circuit, ensuring the system stability and system safety under extreme conditions.

    ● Layered independently-sealed ventilation channel and re-dundant fan, circuit boards with protective paints and a dust filter embedded make it highly efficient to dissipate heat and protect the product effectively under severe environment.
