2.4.2 Flexible

battery

management

This equipment employs a flexible battery management which avoids premature deterioration of battery life
by advanced management of battery charging and preventive failure diagnostics.

The major benefits are:

• AC-ripple free battery charging due to a dc-dc charger separated from the rectifier and inverter.
• Wide range of number of 12V battery blocks; depending autonomy times.
• UPS's wide input voltage operating window extends the battery life due to fewer 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.

2.4.3 Decentralized Parallel Architecture (DPA)

The PowerWAVE 8000-RI DPA system features DPA paralleling technology that provides n+x redundancy
without introducing a single-point-of-failure. The modules utilizing the DPA technology are completely
autonomous be means of individual power units, bypasses, CPUs, control panels and separate battery
configuration.
