The Technology
Intelligent Module (IM)

Each module is a complete UPS. Thanks to Centiel’s 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.

Hot-Swappable without Human Error
CumulusPower ™ modules can be swapped without the need to switch over the load to bypass. Besides that, a per-module parallel isolator fiscally isolates the module from the system reducing the risk of human error and increasing system Availability.

Distributed Active-Redundant Architecture (DARA ™)
The architecture of the CumulusPower ™ was designed to respond to the highest availability requirements, through the implementation of the system’s distributed decision-making in an event of a critical failure, and a correct management of the load sharing. The communication between the Intelligent Modules is accomplished by means of a fully redundant TripleMode ™ communication BUS.
