MUST 30-120

3 Phase Modular
UPS

Finally the benefits of Modular ups are for all

MUST 30-120
The MUST 30/120 is an uninteruptible
power supply, three phase input/
output, ranging from 15 kVA to 120 kVA
(equipped with 15 kVA UPS modules), a
double conversion system, provided of
DSP technology, designed to work for
redundant applications (N+1).

Each module is a complete and independent UPS:

• Three phase rectifier

• Battery charger
• IGBT inverter
• Static switch
• DSP control logic

A very powerfull DSP of last generation.

That reduces the number of the external
components
SYSTEM ADVANTAGES
1. Highest reliability ( MTBF of the suppling chain 100 times more than the stand alone UPS)

2. Replacement of the fault module, with no supply interruption, (Hot swap)

3. Time to replace the module < 3 min

4. Power increasing simply by adding a module unit

5. Very low maintenance costs

6. Each module is a complete and independent Uninteruptible Power Supply

The MUST system
1. MINI MUST 30
MINI MUST is the Entry Level to the MUST Family. It is the ideal solution to supply
a medium load that requires the redundancy or the possibility to expand the
power in the future. Its advantages win against any stand alone ups solution.
The solution is very compact and with the possibility to expand also the autonomy
adding up to 3 battery banks in the same cabinet. Power ranging from 15 kVA
to 30 kva (2 modules), 19’’ rack mounted with the internal battery pack.

2. MUST 60
Modular UPS three phase system ranging from 15 kva to 60 kva, 19’’ rack
mounted with the internal battery pack. This solution can include 4 modules
15 kva providing the following back up time at 75% of nominal load.

If redundancy is requested (N+1 modules) the max output power will be
45 kVA

3. MUST 120
Modular UPS three phase system ranging from 15 kVA to 120 kVA, 19’’
rack mounted, designed for external battery cabinet. The max output
power of the MUST cabinet is 120 kVA ( 8 modules 15 kVA/each).
The battery pack are included in the external cabinet. If redundancy is
requested ( N+1 modules) the max output power is 105 kVA.

4. Modular battery cabinet (2000x1000x800 HxDxW)
It is designed to include up to 40 x 100 Ah battery blocks. This battery
pack, with a 75% of the max load, allows a standard autonomy of 20
minutes. Longer back up time is possible simply adding battery cabinets,
working in parallel or using other battery packs in shelves.
