The system uses unique on-line three transformation of structure. It is operated in the way of three-single-out, three-three, single-entry three, single-entry single out the operating mode without master-slave parallel design. The entire system does not have a single point of failure and the entire system consists of a static Switch Module, the system control module, 1-10 power modules in parallel form. The static switch module is mainly used for quick switch between inverter output and AC bypass switch to fully improve system’s security and reliability of power supply; system monitoring module can automatically carry out float conversion and current-limiting charging of batterries,. It is equipped with functions of temperature compensation and self-discharge detection. Through the LCD large-screen liquid crystal display, real-time understanding of the system’s working state and query of all kinds of event information is available; power module can be configured in accordance with the users’ needs for capacity and freely expanded by using hot-swappable form. Built-in AC isolation transformer can isolate the input electricity, battery packs and exchange to provide high-quality sine wave output and all-round protection. RS232, RS422, RS485 communication interface, standard maintenance manual switch, C-class lightning protection module, SNMP adapter are provided to carry out remote network monitoring and multi-channel dry contact output. Compared with traditional UPS systems, Powerstar modular UPS’ MTBF and MTBCF, is 1.5 times and 3 times the traditional UPS respectively. Its perfect protection and safety applicability will mutiply the protection time of the system and the users’ load equipment ,which is not only safe and reliable, but also save users’ initial investment and provide convenience for the upgrading.

        Electric Power spikes, surges, inductive electrical equipment and frequent switches resulted to large voltage fluctuation, which posed a great threat to the normal use of the equipment,. In order to tackle the problem and other problems, like poor working environment, Powerstar, based on its accumulated experience in power electronics and combined with modern advanced technology in modular UPS uninterruptible power supply systems, adopted the technology of dust-, shock-, and high temperature-proof in its chargers and take input isolation transformer as the power’s standard device so as to avoid damages to power system caused by external shocks.

        Powerstar Modular Series UPS has won attention and praise once it has benne launched. Powerstar will will provide users with more comprehensive, high quality power protection through concrete action. Powerstar is bound to create greater value for users. (Correspondent: Powerstar Power)
