MODULAR UPS COMBO CABINET (MPX 100 CBC)
The Modular Combo Cabinet may contain up to 4 Power Modules (PM), 1 Bypass Module (BM) and 6 battery shelves. Each shelf
may contain 4 Battery Units (BU). The BU contains 10 x 12V batteries (refer to “Modules and Units” chapter).
PMs are UPSs connected in parallel in order to increase reliability in the supply of power to the connected load and to increase
the power available at the output.
The load that can be applied to a Modular UPS Cabinet can be higher than the load that can be sustained by each unit thanks to
automatic power-sharing. Increased reliability is only achieved on condition that the total system power, with one or more PMs
deactivated, remains higher than the demand. This condition is always achieved by adding at least one redundant PM to the
minimum number of elements required to power the load, so that after the automatic exclusion of a faulty PM, the power supply
can continue as required.
Each PM is equipped with a smart control unit, connected through a data bus with the other PMs within the system, achieving a
high reliability distributed logic.
Note: the redundancy level required by the PMs may be set-up during the initial configuration.
The Bypass Module (BM) operates as the central AUTOMATIC BYPASS for the whole Modular UPS Cabinet (ref. to chapter
“Modules and Units”).
In order to further increase the power of the system, multiple Modular UPS Combo Cabinets can be connected in parallel, up to
4.
CAUTION: the Modular UPS Combo Cabinet can use both internal batteries and external batteries. It’s mandatory to use
only modular “MPW Battery Cabinets” as the external battery source if the modular internal Battery Units are installed.
The Modular Combo Cabinet has an electronic supervision system which, through voltage and current sampling, is able to
measure the condition and any anomaly within each of the Battery Units. The collected data is sent to the system through a data
bus and shown on the display of the Cabinet.
In addition, within the Modular Combo Cabinet there is an SWBATT disconnection switch which enables the BUs to be completely
disconnected from the Modular UPS Cabinet. The cabinet also features an opto-isolated input which enables the SWBATT switch
to be opened remotely.
CAUTION: each shelf of the Modular Combo Cabinet can be filled (with the 4 BUs) based on the autonomy requirements
of the system (up to a maximum of 6 internal shelves). The minimum number of fully populated battery shelves must
follow the rules set out in the table below:
