  • Double Conversion UPS

    12

    Double Conversion UPS performs

    dual conversion of power, providing

    protection against most main power

    related issues.

  • On-Line Battery

    15

    On-Line battery lets the UPS

    operate during power failures

    without switching, since the battery

    is linked directly to the DC bus.

  • De-centralized battery

    De-centralized battery system in some well-known UPS

  • Centralized battery

    17

  • Battery cabinets

    In most cases the battery cabinets are external.

    Nevertheless, internal hot-swap battery cabinets for low

    capacities are available as well:

    64/60 x 20AH/12V

    64/60 x 20AH/12V

    64/60 x 5AH/12V

  • Static Switch

    Distributed Static Switch:

    In this case, each UPS module has got its own internal static

    switch

    Outputs of all modules are linked together and are wired

    directly to the load19

  • Static Switch (cont..)

    Centralized Static Switch:

    When implementing centralized topology, outputs from all

    modules are linked together to the inverter input of the static

    switch module.

    There is one device that handles the inverter / bypass switching20

    The modular design of Power+ UPS provides a cost effective redundancy

    with higher efficiency than conventional parallel UPS systems.

    For even more power and extra redundancy,Power+ can be put in parallel

    de-centralized configuration. This will enable a combination of both vertical

    and horizontal redundancy!
