Each module is a complete UPS. Thanks to Centiel’s long experience in module-design, the CumulusPower™
Intelligent Modules are equipped with three independent power converters, one static bypass, all hardware and all
software (intelligence and monitoring) functions, making them fully independent and capable of safely isolating from
the multi-module system whenever an internal fault occurs.

High Efficiency 97.1% (VFI)
With the best in class efficiency of 97.1% in double
conversion mode (VFI), CumulusPower™ provides
the lowest Total Cost of Ownership and lowest
carbon footprint.
Maximum Efficiency Management (MEM)
CumulusPower™ incorporates an Intelligent MEM
function which matches the number of modules
to the load demand by monitoring the level of
optimum energy efficiency.
At low load levels, any modules no longer required
to maintain redundancy are placed into Active-Sleep
mode, reducing overall energy consumption.
Active-Sleep modules are instantly online when
load increases, maintaining maximum
availability at all times.

>10 years DC capacitor life +“plug-and-play”
AC capacitators
• Reduces TCO
• Simplifies maintenance
• Lower cost in spare parts(MTTR)
and simplifies routine maintenance.
Serviceability
Modular design allows fast replacement of Intelligent
Modules, reducing Mean Time to Repair (MTTR),
maximising availability and reducing costs
