ABB Develops AI-optimized 415V 3-phase UPS for Large-scale Data Centers

ABB has unveiled its latest uninterruptible power supply (UPS) system — the AI-ready MegaFlex UL UPS for 415V 60 Hz applications — designed to meet the evolving load profile demands of today’s modern data centers.  Engineered with high-efficiency, scalability, and reliability, this new system reinforces ABB’s position at the forefront of intelligent power management.

Now available in the UL marketplace, the 415V MegaFlex UL UPS meets the highest safety and performance standards. It delivers intelligent power continuity to data centers, optimizing energy usage while preventing costly downtime and disruptions.

“The addition of the 415V UL offering enhances our comprehensive range of ABB 3-phase UPS systems,” said Sébastien Surply, Head of Power Protection, ABB Electrification. “It delivers a high-efficiency solution specifically tailored for the UL market. The MegaFlex UL UPS exemplifies our commitment to innovation and engineering excellence by delivering robust, AI-integrated power continuity. It empowers our customers to run smarter, more efficient data center operations.”

Built for scalability and resilience, the MegaFlex UL is designed to operate within high resistance ground (HRG) environments, ensuring continuous power delivery to critical equipment. As infrastructure needs grow, the system can be expanded for capacity and redundancy, making it ideal for dynamic data center environments.

Efficiency is at the core of the MegaFlex UL 415V system. Each phase operates with its own current, reducing stress on wiring and allowing for the use of smaller, cost-effective wires and transformers. This not only lowers installation and maintenance costs but also reduces overall electricity usage — a crucial benefit for large-scale operations.

By offering both 415V and 480V UL-compliant UPS systems, ABB enables data centers to select the optimal voltage configuration for their specific environments. This flexibility ensures seamless integration with existing infrastructure, enhances operational efficiency, and supports long-term performance goals.

With the launch of the 415V MegaFlex UL UPS, ABB continues to deliver future-ready power protection that meets the high demands of today’s AI-driven data centers.
