MegaFlex UL – The best in power protection (ABB)

The MegaFlex UL uninterruptible power supply (UPS) is designed for critical high-density computing environments such large enterprises, colocation, hosting cloud and telecommunications data centers.

The MegaFlex UL UPS represents the latest technological innovation in the market delivering the best and most reliable power protection for large infrastructures. The UPS is a three-phase, 480V double conversion uninterruptible power supply. Its topology is monolithic based utilizing 400 kW power modules with power availability from 1,200 to 1,600 kW in one UPS cabinet configuration. MegaFlex UL is flexible system architecture ready and supports N+1, 2N, 2N+1, N+N, 3N/2, and catcher system configurations.

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.
