(Issue 2.1 Oct. 2009)
Unfortunately this can lead to a single-point-of-failure for the whole
system if the master logic or communication to the slaves fails.
The DPA technology uses Multi-Master logic with separated independent
regulation and logic buses to maintain the highest system availability. DPA
technology enables a parallel redundant system providing 100%
conditioned power at all times. The 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 technology allows up to ten UPS modules to supply the same load in
parallel and redundant configuration.
2.3 PowerWAVE 9000 DPA Series - Models
The PowerWAVE 9000 DPA UPS is available in a range of power ratings
between 10 and 250kVA. A range of cabinets or frames and modular power
assemblies offers unrivalled configuration options and upgrade paths.
2.4 Single and Multi-Cabinet Parallel Configurations
The PowerWAVE 9000 DPA UPS has unique paralleling features:
Single/Parallel-Module Configurations:
A Single-Module:
If a configuration consists of one single Module it is
defined as a Single-Module Configuration.
Parallel-Modules:
. A Parallel-Module is a Module that is operating in
parallel with other equivalent Modules.
Single/Multi-Cabinet Configurations:
Single-Cabinet Configuration:
A single-cabinet configuration means that
there are no cabinets operating in a chain.
Multi-Cabinet Configurations:
It is possible to parallel Cabinets into a
Multi-Cabinet Configuration in order to increase the number of paralleled
Modules.
