Schneider Electric Galaxy VX | 500–1500 kW UPS

Scalable, flexible, high performance power protection to meet the changing needs of your rapidly expanding business

Schneider Electric Galaxy VX UPS Close Up

Galaxy VX is a highly efficient, modular three-phase UPS scalable from 500 to 1500 kW in a single unit that provides high performance, scalability, and flexibility. Its scalability accommodates the changing needs of your rapidly expanding business, and its exceptional performance and abundance of cost-saving features reduce your energy costs and total cost of ownership (TCO). Galaxy VX is the ideal UPS for today’s large data centers, cloud and colocation facilities, as well as mission-critical applications.

  • Reduces TCO with up to 99% efficient third-party certified Class 1 ECOnversion operating mode
  • Enables on-site UPS expandability with 250 kW power cabinets and the ability to parallel up to four units for capacity or redundancy
  • Improves UPS reliability and lifecycle with patented four-level inverter technology
  • Optimizes your return on investment, and increases your UPS and energy storage utilization with dispatchable operation
  • Speeds up your deployment time, increases on-site reliability and reduces start-up costs with Smart Power Test (SPoT) mode
  • Compatible with low TCO, high-performance Lithium-ion batteries
  • Lowers maintenance and replacement costs with modular architecture

Scale up easily with modular design and high-density footprint 

Modular design

The Galaxy VX system scales using 250 kW power cabinets. Power cabinets can be added after initial installation to allow for load growth or increased redundancy.

Expand Galaxy VX from 500 kW up to 1500 kW N+1

  • New footprint-optimized 1250 kW input/output (I/O) cabinet supports up to 1250 kW N+1 in a single frame
  • Also scalable up to 1500 kW N+1 in a single UPS with the 1500 kW I/O cabinet

ECOnversion mode

Enjoy the high-test energy savings available today without sacrificing load protection—our patented zero-break transfer design offers peace of mind:

  • World-class efficiency up to 99%
  • Excellent load protection with certified third-party Class 1 performance per IEC 62040-3
  • Zero transfer time to continuously-charged batteries or double conversion mode; inverter is always on and active
  • Input power factor correction
  • Porgrammable scheduling available

How Does ECOnversion mode work 

  • Bypass input powers the load
  • Active inverter supplies power factor correction and harmonic compensation
  • Patented bypass silicon controlled rectifier (SCR) control prevents input short circuit from affecting critical loads
  • Selectable input voltage, frequency, and total harmonic distortion (THDU) windows ensure the UPS operating mode is optimized for site-specific power conditions

Increase reliability, predictability, and performance with advanced Galaxy VX technology

Speed up deployment time, reduce start-up costs, and increase on-site reliability of the UPS operation by using the Smart Power Test (SPoT) mode before connecting your critical load.

SPoT (Smart Power Test) SPoT enables the field service engineer (FSE) to test the UPS with full capacity current flow through important components and converters, without using a large system input current and without needing a load bank connected to the system or other system modifications.

  • Simple, easy, and safe method to test the UPS at full power
  • Can be conducted after service, repair, upgrade, or commissioning of UPS installation to verify system is properly installed
  • Reduce risk to load and improve product quality
  • Significant cost, time, and power savings

Increase reliability and peace of mind by adding a power module cabinet to achieve N+1 redundancy, or by paralleling up to four UPSs for capacity or redundancy.

Smart paralleling and fault-tolerant design

Inherently redundant design allows for any power cabinet to act as a redundant 250 kW block. Load sharing in parallel is done by matching the percentage output of each system depending on capacity availability. Redundant parallel communication cables increase overall system resiliency.

Dispatchable UPS

Unlock the value of your UPS: Maximize savings, generate revenue, and improve resiliency by dispatching stored battery capacity.

Lithium-ion batteries are increasingly being utilized to provide a variety of valuable grid services and generate steady income streams. With modern data centers leveraging Lithium-ion battery technology, such income streams are also available to data center owners. This added functionality enables quick return on investment while increasing system reliability and providing continuous state of health data.

  • Reduce utility demand charges
    • Offset peak-load demand by dispatching excess capacity from Lithium-ion batteries
  • Minimize time-of-use tariff charges
    • Reduce energy consumption during peak hours by load shifting to non-peak hours
  • Increase system reliability 
    • Improves overall performance by cycling batteries to validate their state of health
  • Generate new revenue streams
    • Create additional revenue by participating in utility programs and electricity markets
