Battery-Free UPS for the Power Behind AI

AI is rapidly changing the rules of power. 

The power infrastructure supporting it must evolve just as quickly. 

Traditional data centers were built around relatively predictable server loads. 

AI data centers are different. 

Driven by high-density GPU clusters and increasingly demanding AI workloads, today’s data centers are larger, denser, and more power-intensive than anything that came before them. They require power systems designed for continuous operation, exceptional power quality, and long-term reliability. 

There is nothing traditional about AI infrastructure. 

So, the power infrastructure cannot be traditional either.  

Active Power provides proven, battery-free UPS protection for AI data centers delivering mission-critical ride-through and power continuity without the battery degradation, replacement cycles, and potential exposure to thermal runaway associated with conventional battery-based UPS systems. 

Battery-free. Rugged. Proven in AI applications.

The AI Power Challenge

The challenge is not simply generating more power. 

It is delivering stable, resilient, high-quality power to facilities operating at unprecedented scale. 

Generation, controls, stabilization, distribution, energy storage, and UPS protection all play a role in supporting modern AI infrastructure. 

No single technology solves the entire challenge. 

Active Power’s role is clear: 

Battery-free UPS protection for the critical AI load.

Reliability for Mission-Critical Operations

Power Quality

Battery-Free Energy Storage

Lower Lifecycle Complexity

Reliability for Mission-Critical Operations

Protect critical AI workloads with proven UPS technology designed for environments where downtime is not an option. Flywheels are rugged, fast-responding, and built for demanding environments. 

Power Quality

Deliver clean, conditioned power to sensitive AI infrastructure and protect operations from power disturbances and utility fluctuations. 

Battery-Free Energy Storage

CleanSource® uses flywheel-based kinetic energy storage instead of battery banks. Eliminate battery degradation, replacement cycles, thermal runaway exposure, and battery disposal requirements while delivering consistent performance throughout the system’s service life. 

Lower Lifecycle Complexity

Reduce maintenance requirements, cooling demands, and long-term operational costs associated with conventional battery systems. No battery replacements, lower maintenance burden, long service life, and a lower total cost of ownership. 

A Traditional UPS Role — Delivered Differently

Active Power performs the same critical role expected of a UPS: protecting the data center from power interruptions and power quality events. 

The difference is how the energy is stored. 

Conventional UPS systems rely on chemical batteries. CleanSource® flywheel UPS technology uses battery-free kinetic energy storage to provide proven ride-through power and power quality protection for mission-critical AI environments without the lifecycle burden of conventional UPS batteries. 

When upstream power is interrupted, stored kinetic energy is immediately delivered to the critical load until standby generation or backup power sources become available. 

It is UPS protection without the battery burden. 

Traditional Battery UPS VS Active Power Flywheel UPS

Built for Mission-Critical Infrastructure

Active Power is part of Piller Power Systems, a global leader in UPS and power conditioning technology with more than 100 years of experience. 

Together, Active Power and Piller technologies protect mission-critical facilities around the world, including hyperscale data centers, financial institutions, government infrastructure, exchanges, healthcare facilities, and other critical environments where uptime is essential. 

AI data centers are the next frontier. 

They require power systems built for the reality of AI. 

Part of a Gigawatt-Scale AI Power Ecosystem

Active Power is not approaching AI infrastructure in isolation. 

As part of Langley Power Solutions, Active Power works alongside Bergen Engines, Piller Power Systems, and Marelli Motori to support complete power architectures for AI data centers. 

Together, these technologies support the entire power chain; from generation and conditioning to UPS protection at the critical load. 

Because the AI power challenge is no longer just about buying equipment. 

It is about designing complete power architectures capable of supporting the speed, density, and scale of AI.
