When apparent power (VA) equals true power (Watts), the UPS is said to be unity rated (or power factor
correction=unity=maximum efficiency). The unity rated R12000 XR is more efficient, and provides
improved power flow and thermal management (vs non-unity rated UPSs). Also, the R12000 XR uses
online (also known as the double conversion) technology. The online UPS converts the incoming facility
AC power (including sags, surges, spikes, noise) into DC power that feeds the battery. The DC battery
output is then converted into clean, filtered, and constant AC voltage output (at a pre-set desired value),
ensuring reliable, conditioned power feeding to your connected servers and other IT equipment.
Through a combination of four 3KW/3KVA modules, the UPS R12000 XR meets rigorous redundancy
and fault tolerant requirements - where "x" is the number of reserve modules should a module fail. A
unique patented state-of-the-art wireless paralleling technology allows all the modules to function
independently of each other (each electronics module houses its own electronics and also the logic).
Should one of the modules fail then the remaining modules seamlessly redistribute the new load
requirement through an automatic load sharing process (with transparent transfer time). And since both
the logic and electronics are housed in the each of the individual 3kVA modules (and not in the
enclosure as with most competitive UPSs), this technology eliminates system-level single point of failure.
Scalable from 3KVA to 12KVA, the UPS R12000 XR allows the following "N+x" parallel redundant
configurations:
12 KW (N+0); no module in reserve
9KW (N+1); one module in reserve
6KW (N+2); two modules in reserve
3KW (N+3); three modules in reserve
With its high speed Digital Signal Processing (DSP) design, the R12000 XR enables paralleling for
redundancy with no inter-module communication. Via a patented wireless paralleling technology, all
necessary information for paralleling is available using only the modules' output power wave form. By
using a mathematical firmware approach to paralleling for redundancy, wireless paralleling eliminates
single points of failure such as in communication wiring and added circuitry between the modules.
Therefore, the 100% mathematical firmware is more reliable than traditional paralleling that uses
communication wiring between modules. The load share control algorithms maintain synchronization
and load balance by constantly making minute adjustments to variations in the output power
requirements. In a traditional parallel UPS system, load sharing required communications wiring between
the modules, which introduced single points of failure (if any part of the communication link failed, so did
the system). The wireless technology in the R12000 XR, eliminates the necessity for inter-module
communication. By eliminating communication wiring and added circuitry between the modules, the
R12000 XR provides the highest level of reliability and system availability.
Unlike traditional paralleling techniques, R12000 XR uses a unique patented wireless technology
that eliminates system level single points of failure.
By using "peer" configuration, as opposed to "master-slave" configuration, this wireless technology
ensures that each module is operating independently.
Each module functions autonomously; also, each electronics module houses its own control logic;
and the voltage in each individual battery module is individually managed (versus as just an
overall battery management).
