The Modular Combo Cabinet may contain up to 3 Power Modules (PM), 1 Bypass Module (BM) and 5 battery shelves. Each shelf
may contain 4 Battery Units (BU). Each BU contains 10 off 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 load and the power available at
the system 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
the 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 load required. This condition is achieved by adding at least one redundant PM to the minimum
number of PMs 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 of the system, achieving a high
reliability distributed logic.
Note:
the redundancy of the PMs may be set-up during configuration.
The Bypass Module (BM) operates as the central AUTOMATIC BYPASS for the entire 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. The maximum configuration will be therefore 12 PMs connected in parallel, of which at least 4 are redundant.
CAUTION: the Modular UPS Combo System can use internal batteries, external batteries or both. The system must share
all internal and external batteries. It’s mandatory to use MPW Battery Cabinets as an external battery source if internal
Battery Units are used. Is not allowed to connect other types of external batteries if internal Combo batteries are used.
The Modular Combo Cabinet has an electronic supervision system which, through voltage and current sampling, is able to
measure the condition and any anomaly of each Battery Unit. 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 a 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 5 shelves). The minimum number of fully populated battery shelves must follow the
rule set out in the table below:
