Galaxy PX UPS: Embedding the “Core Formula” of the AI-Compute Era into Just 0.6 m²
BEIJING — Schneider Electric introduced its latest three-phase UPS, the Galaxy PX, positioning it as a new power-infrastructure standard for AI-driven data centers. As computing workloads skyrocket and energy density climbs to unprecedented levels, the company aims to solve one of the industry’s biggest bottlenecks: how to deliver safe, efficient, and scalable power supply in extremely limited space.
The launch highlights Schneider Electric’s strategy to reshape the power-support layer for the next wave of intelligent computing, where power systems must respond as quickly as GPUs think.
AI Workloads Reshape Data-Center Power Needs
The rise of large AI models pushes power density in server racks from 20–30 kW toward 80–100 kW. Facilities now try to triple power and cooling capacity without expanding footprint, often under severe land-use constraints.
Compute loads in AI training also fluctuate sharply. Power draw can swing between maximum load and idle states within seconds, stressing UPS systems that were originally designed for relatively smooth curves.
Schneider Electric notes that future data centers must satisfy three core expectations at the same time:
-
Absolute safety for operators and equipment,
-
High electrical and spatial efficiency,
-
Lower total cost of ownership under tightening carbon-reduction goals.
The Galaxy PX aims to deliver a solution that meets all three.
A 0.6 m² Cabinet Designed for High-Density AI Loads
Schneider Electric built the Galaxy PX around a compact footprint of roughly 0.6 m², making it one of the densest UPS platforms in its class. The new lineup covers 300–600 kVA applications and uses 67 kW power modules—larger than common 50–60 kW designs—to pack more power into fewer modules.
The company says this approach reduces installation space by 20–50% compared with traditional solutions while maintaining compliance with international safety and performance standards such as IEC 62477 and IEC 62040.
The UPS also targets facilities pursuing high-density AI cabinets or accelerated GPU clusters, where every square meter counts.
Efficiency that Directly Reduces Energy and Cooling Costs
Schneider Electric emphasizes that the Galaxy PX improves operational efficiency across different load conditions:
-
Double-conversion mode reaches up to 97.5% efficiency.
-
E-conversion mode reaches up to 99% efficiency, allowing more of the incoming power to feed compute rather than dissipate as heat.
In high-density AI scenarios—where facilities must reduce both energy consumption and cooling loads—these efficiency gains translate into lower electricity cost and measurable progress toward carbon-reduction targets.
The company positions these efficiency levels as one of the core reasons the Galaxy PX fits the sustainability direction of next-generation data centers.
Safety Upgraded for High-Risk Operating Environments
Schneider Electric highlights safety as the most critical design element. The Galaxy PX introduces an enhanced Live Swap architecture that limits arc-flash energy to below 1.2 cal/cm², staying within thresholds that allow engineers to perform module replacement in normal workwear.
This approach reduces maintenance risk and avoids disruptions associated with powering down equipment or requiring heavy protective gear.
The UPS also integrates real-time sensing across both the AC and DC sides. It monitors external load-switch behavior, battery conditions, and fault signals to react instantly to abnormal energy flow, protecting people and equipment during grid disturbances.
Built to Track the Fast “Heartbeat” of AI Compute Loads
Unlike traditional IT loads, AI workloads tend to “breathe” — moving rapidly from peak to low demand. The Galaxy PX supports fast load-step performance across 30–150% operating range and adjusts within 50 milliseconds.
This responsiveness means the UPS can follow GPU power spikes during model training and sudden drops during idle or inference periods, ensuring power stability even under extreme fluctuations.
The system also tolerates short-circuit currents up to 65 kA, which helps data centers integrating renewable power sources or modular power blocks that create more complex, less predictable grid environments.
A Foundation for AI-Ready, Sustainable Data Centers
Schneider Electric states that the Galaxy PX is not only a hardware upgrade but also a rethinking of how energy infrastructure supports the AI-compute stack.
By combining compact design, safety-first architecture, fast load-response capability, and high operational efficiency, the Galaxy PX aims to become a foundational component for AI-ready, low-carbon, high-density facilities worldwide.
As data-center operators race to expand computing power while staying within space, regulatory, and sustainability constraints, Schneider Electric believes the Galaxy PX provides the “core formula” needed to build the next generation of intelligent infrastructure.
