Schneider Galaxy VX UPS 500kW – 1250kW | Modular 3-Phase UPS with 125kW Incremental Scalability

The Schneider Galaxy VX UPS is a premier, large-scale power protection solution designed for hyperscale data centers and demanding industrial enterprises. This series stands out for its high-density 125kW modular power cabinet architecture, allowing for precise scalability from 500kW up to 1250kW. By incorporating Schneider’s innovative 4-level inverter technology and patented ECOnversion™ mode, the Galaxy VX achieves up to 99% efficiency. It is the ultimate choice for organizations seeking to minimize Total Cost of Ownership (TCO) while maintaining uncompromising reliability and fault tolerance in mission-critical environments.

Key Functions and Features

125kW Modular Granularity: Built with 125kW power blocks, providing more granular scalability than traditional large UPS systems. This allows users to pay-as-they-grow and optimize initial capital investment.

Smart Power Test (SPoT): Features the “E-Spot” mode, which allows for full-scale load testing at the site without the need for an external load bank. This simplifies commissioning and reduces operational risks.

Class-Leading 99% Efficiency: In ECOnversion™ mode, the system provides Class 1 compliant power protection while achieving 99% efficiency, drastically lowering electricity bills and carbon footprint.

Advanced 4-Level Inverter: Delivers 97% efficiency in double conversion mode, reducing component stress and enhancing the overall lifespan of the UPS compared to standard 3-level designs.

Lithium-ion Battery Integration: Fully compatible with high-performance Li-ion battery cabinets, offering up to 70% space savings, longer service life, and simplified maintenance.

N+X Redundant Architecture: Supports internal and system-level redundancy to ensure the critical load remains protected even during module maintenance or component failure.

Frequently Asked Questions (FAQ)

Q1: Why is the 125kW power cabinet design important?

A: Most mega-UPS systems scale by 250kW or 500kW. The 125kW increment offers finer control over power capacity, allowing you to scale up more accurately as your load increases, avoiding over-provisioning.

Q2: What is the “Smart Power Test” (SPoT) or E-Spot mode?

A: SPoT allows the UPS to simulate a full load test using its own internal power components. This means you don’t have to rent expensive load banks during commissioning, saving time and money.

Q3: Does 99% efficiency in ECOnversion™ mode compromise protection?

A: No. Schneider’s ECOnversion™ mode meets IEC 62040-3 Class 1 standards. It provides active harmonic filtering and seamless transition to battery power, ensuring your critical load is never exposed to raw utility power.

Q4: How does the 4-level inverter benefit industrial applications?

A: The 4-level design reduces the voltage stress on IGBTs and filters, which lowers heat generation and increases the overall reliability and service life of the system in harsh environments.

Q5: Can I use different battery types with Galaxy VX?

A: Yes. While optimized for Lithium-ion (which we highly recommend for space and TCO savings), it also supports VRLA (lead-acid) and Ni-Cd batteries.
