Keor FLEX - Three-Phase Modular UPS | Up to 1.2 MW

As data centers expand to meet growing demands from cloud computing, AI workloads, and colocation services, the need for energy-efficient and scalable power solutions has never been greater. Keor FLEX is a high-efficiency modular uninterruptible power supply (UPS) designed for high-density data centers, featuring a modular, hot-swappable architecture that enables seamless growth with zero downtime, ensuring continuity of services for mission-critical operations. Delivering market-leading 98.4% efficiency in double conversion mode, Keor FLEX reduces energy consumption, cooling costs, and Total Cost of Ownership (TCO). Its scalable design—supporting up to 1.2 MW in a single frame and expandable to 4.8 MW—makes it the ideal solution for colocation, hyperscale, AI, edge computing, and smart-grid ready installations.

Key Benefits of Keor FLEX High-Power Modular UPS

Unmatched Efficiency

Achieves up to 98.4% in VFI mode and 99% in ECO mode using Silicon Carbide (SiC) technology, minimizing energy losses and OPEX while supporting sustainability.

Zero Downtime Scalability

True modular architecture with hot-swappable power and bypass modules enables pay-as-you-grow scalability and zero-downtime maintenance.

Maximized Power Density for Constrained Space

1.2 MW in just 2.8 m² — maximizing white space utilization.

Thermal Efficiency for Data Center Environments

Keor FLEX incorporates advanced Silicon Carbide (SiC) technology to minimize internal heat generation. This design enhances Power Usage Effectiveness (PUE) by reducing the cooling load, leading to lower energy consumption and improved overall efficiency in data center operations.

Turn Your UPS into a Smart Energy Asset

Supports peak shaving, fast frequency response, and renewable energy integration, with seamless BMS compatibility for energy optimization.

Resilient Design for Maximum Uptime

Redundant modular design with a fault-tolerant busbar ensures continuous operation, while front access and hot-swappable components cut maintenance time to under 5 minutes.

Real-Time Diagnostics at Your Fingertips

10-inch touchscreen and multi-colored LED status bar provide real-time insights, predictive diagnostics, and intuitive system control.

Right-Sized Power with Future Growth in Mind

Delivers up to 1.2 MW per UPS frame using 12 x 100 kW modules, allowing scalable expansion without disruption.

Flexible Load Sharing Across Systems

Supports up to 4 parallel units for a total of 4.8 MW, enabling N+1 or 2N redundancy for mission-critical reliability.
