ABB MegaFlex UL UPS is based on ABB’s redundant parallel architecture™ (RPA) allowing the UPS to run in a parallel arrangement, eliminating any single point of failure with true redundancy. RPA reduces operating footprint and provides a scalable paralleling approach that increases system reliability. It also eliminates the need for external paralleling equipment or centralized bypass and master control.
