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.

Why Keor Flex?

Unmatched Efficiency

Unmatched Efficiency


With up to 98.4% efficiency in VFI mode and 99% in ECO mode, Keor FLEX delivers industry-leading energy savings. Utilizing Silicon Carbide (SiC) technology, it ensures maximum performance with minimal losses, reducing energy waste, operating expenses (OPEX), and supporting sustainability goals.

Scalable & Hot-Swappable Modules

Scalable & Hot-Swappable Modules


Engineered for flexible, pay-as-you-grow scalability, this true modular design allows hot swapping of power and bypass modules, ensuring zero downtime during maintenance. This approach enables a right-sized investment, expanding capacity only when needed to optimize efficiency and costs.

Cooling Optimization

Cooling Optimization


With lower heat dissipation designs, Keor FLEX significantly reduces cooling energy consumption. Minimizing thermal output directly improves Power Usage Effectiveness (PUE), enhancing overall data center efficiency.

Smart-Grid & Renewable Energy Integration

Smart-Grid & Renewable Energy Integration


Designed for intelligent grid interaction, this high-quality system supports peak shaving, fast frequency response, and seamless renewable energy integration. By reducing dependency on non-renewable power sources, it enhances sustainability while ensuring smooth integration with Building Management Systems (BMS) for optimized energy efficiency. 

Unmatched Power Resilience & Serviceability

Unmatched Power Resilience & Serviceability


The innovative internal busbar system enhances reliability by eliminating single points of failure. With multi-module redundancy, it ensures uninterrupted power, preventing disruptions and maximizing system resilience for mission-critical operations. Full front access simplifies servicing, reducing Mean Time to Repair (MTTR) to under 5 minutes.

Advanced Display & Monitoring

Advanced Display & Monitoring


The system includes a 10-inch touchscreen display and a multi-colored LED status bar, offering an intuitive communication interface that delivers real-time power insights, predictive diagnostics, and complete system control. The LED status bar provides immediate visibility of system conditions, enabling quick and informed decision-making.
