2: General Description
Hot-swappable modules
In a redundant module system the unique ‘hot-swappable’ feature enables a UPS module to be added or removed from its
cabinet whilst the system is still powered. This can be done without disturbing the load or transferring it to the bypass
supply.
Note: In a non-redundant system the load will unavoidably have to be transferred to the bypass supply while a module is
shut down or removed from the system.
Advanced booster technology
The UPS module’s inbuilt advanced booster technology results in a perfect sinusoidal input power quality at 0.99 input
power factor with a harmonic content of less than 3-4% THDi. This leads to a more reliable system operation together with
savings in generator and transformer sizing due to reduced winding losses. It also means that the traditional input
harmonic filters, still used by some systems, are not required.
The high power factor presented by the UPS on the incoming mains supply minimises cabling and fusing costs due to the
reduced reactive power consumption which, together with the accompanying low harmonic currents, provides the
following benefits:
• No additional losses in wires and cables
• No extra heating of transformers and generators
• No over sizing of generators
• No false circuit breaker tripping and malfunction
• No erratic operation of computers, telecommunications, monitors, electronic test equipment etc.
• No resonance with power factor correction capacitors
Decentralised Parallel Architecture (DPA)
The PW9000DPA S2 system features DPA paralleling technology that provides n+x redundancy without introducing a
single-point-of-failure. Each module contains its individual charger and inverter power units, bypasses, CPUs, control
panels and separate battery configuration, and thereby offers completely autonomous operation.
This unique decentralized design:
• Enables a parallel redundant system providing 100% conditioned power at all time.
• Eliminates the system-level single point of failure inherent in traditional parallel UPS systems.
• Exponentially increases the reliability of the overall system.
Flexible battery management (FBM)
This equipment employs flexible battery charging management which avoids premature deterioration of battery life and
provides preventive failure diagnostics. The major benefits are:
• AC-ripple-free battery charging due to a dedicated dc-dc charger independent from the rectifier and inverter.
• Wide range of number of battery blocks (42-50 x 12V blocks, depending autonomy times).
• Wide UPS 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 the Advanced Battery Diagnosis (ABD) algorithm.
• User-selectable battery tests to ascertain the battery state.
• Optional temperature compensated charging regime to enhance battery life.
