1.3.1.3 Feature : Flexible Battery Management (FBM)
The Flexible Battery Management (FBM) has been designed in all UPS products with the goal to avoid the
deterioration of battery age. The FBM
–
Key Features protect the battery from environmental negative impacts (high
temperature and false manipulations) and avoid deterioration of battery life by advanced management of battery
charging and preventive failure diagnostics. The implemented features result in benefits not only for the end user,
but also to the environment. The battery user will be required to replace his batteries less often. This translates into
financial and environmental benefits. Last but not least a well protected and managed battery is a healthy battery
and hence it enhance the overall availability of the UPS system.
The major benefits are:

AC-Ripple free battery charging due to DC-DC charger separated from the rectifier and inverter

Wide range of number of battery blocks (20-50 blocks of 12V; depending autonomy times and power)

UPS’
S wide input voltage window tolerance extends the battery life due to less discharge cycles

Battery discharge protection caused by load jumps

Proactive battery protection from false manipulations and inadequate charging voltages

Proactive battery failure detection thanks to Advanced Battery Diagnosis (ABD) - Algorithm

User selectable battery tests

Optional temperature compensated charging to enhance battery life
Hence, the function of FBM system is to prolong the battery life considerably compared to traditional systems. In a
traditional online UPS the inverter also causes ripple-current to be fed to batteries causing corrosion.
1.3.1.4 Feature : DPA Technology - Decentralized Parallel Architecture
The UPS product features DPA paralleling technology that provides N+X redundancy without introducing a single-
point-of-failure. The products utilizing the DPA technology are completely autonomous be means of individual
Power Units, Bypasses, CPU’s, Control Panels and separate battery configuration for each single module.
The DPA technology makes it more reliable than traditional paralleling techniques. A parallel UPS system means
the linking together of two or more UPS units in parallel so that in the unlikely event one fails the other can
automatically take up the load. Traditionally a parallel redundancy configuration is achieved by having a random or
fixed master-slave relationship among the UPS units. This master logic gives out individual commands to all the
slaves units. Unfortunately this can lead to a single-point-of-failure for the whole system because if the master logic
or communication to slaves fails, and causes the whole UPS system to be in trouble.
The DPA technology was developed as a Multi-Master logic concept with separated independent regulation and
logic buses to allow parallel capacity system and to maintain the highest system availability. An industry leading
paralleling technology in its own right, the DPA technology enables you to set up a parallel redundant system giving
you 100% conditioned power at all times. Its unique decentralized design eliminates the system level single point of
failure inherent in traditional parallel UPS, and exponentially increases the reliability of the overall system.
DPA UPScale RI technology allows up to six UPS modules to cover the same load in parallel and redundant
configuration. No vulnerable master logic is needed in this design. It provides automatic load sharing and module
level redundancy with nothing other than the power connecting to the DPA UPScale RI
TM
version of UPS modules.
