MegaFlex UL 480V

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

The MegaFlex UL UPS represents the latest technological innovation in the market, providing 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, using 400 kW power modules with power availability from 1,200 to 1,600 kW in a single UPS cabinet configuration. MegaFlex UL is ready for flexible system architecture and supports N + 1, 2N, 2N + 1, N + N, 3N / 2, and catcher system configurations.

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