    ST6-10K is a new-generation product developed by the company. It adopts a series of new technologies in the industry-PFC soft switching technology, three-level inverter technology, PFC and


    Inverter dual hardware current limiting technology. It has greatly improved performance, efficiency, cost, and power density compared with the previous generation products.


    ●The heat generation of key components is reduced, and the efficiency of the mains battery is greater than 94%.


    ●The size of the chassis is reduced, and the power density is increased.


    ●The air volume of the fan is reduced and the noise is reduced.


    ●Rectifier and inverter hardware real-time current limiting protection, the machine stability is better.





    advanced technology:


    ●The latest soft switching technology is used in the PFC boost, which reduces the PFC IGBT


    Voltage spikes and switching losses increase the instantaneous height of UPS withstand lightning strikes


    Pressure resistance.


    ●Using the latest three-level inverter architecture, solve the problem of half-bridge inverter circuit


    With half-wave load, inductive load problem.


    ●Realize the digitization of inverter control, adopt voltage and current double loop control to improve


    The dynamic response speed is high, and the output performance is improved.


    ●The PFC circuit adopts frequency multiplication control, which effectively improves the efficiency of the whole machine.





    Complex grid adaptability:


    ●Ultra-wide input voltage range: 120AC-275AC


    ●Ultra-wide input voltage range: 40Hz-70Hz


    ●Input power factor>0.99


    ● Eliminate all kinds of pollution and interference in the power grid


    ● Faster input current limiting response speed, providing more perfect protection
