About APC Galaxy VX UPS Systems

APC Galaxy VX UPS systems: large-scale double-conversion power protection

The APC by Schneider Electric Galaxy VX is a three-phase, online double-conversion uninterruptible power supply built for large data centres, industrial sites, and mission-critical facilities. Every unit in this series delivers a pure sine-wave output through full online double-conversion, isolating your load from utility disturbances with zero transfer time. The Galaxy VX sits at the top of the APC three-phase lineup, scaling from 500 kVA up to 1500 kVA in a tower (free-standing) form factor, with single-module, N+1 redundant, and field-scalable configurations available. If you are sizing a centralized UPS for a facility rather than a single rack, this is the series to evaluate.

Models in the Galaxy VX series

All models below are online double-conversion, pure sine wave, tower form factor, with 400 V AC output (several also support 380 V / 415 V) and are extended-runtime capable. Power ratings are shown in kVA as carried by each model. This is a representative selection; see the full range below.

The full range below also includes additional scalable and N+1 redundant variants (for example GVX1000K1500HS, GVX1250K1500HS, GVX1500K1250HS and GVX1750K1500HS) that let you start at a base rating and grow capacity or add redundancy without replacing the frame.

How to choose a Galaxy VX

Size by kVA and kW. A UPS is rated in both apparent power (kVA) and real power (kW). Add up the load of the equipment the UPS must support, include headroom for growth, and choose a rating at or above that figure. Because the Galaxy VX is a centralized facility-class system, sizing is usually done with your electrical engineer or integrator against the full connected load.

Single vs. scalable vs. N+1. Single-module units (for example GVX500K500HS) suit a fixed, known load. Scalable units (for example GVX500K750HS) let you license additional capacity later inside the same frame. N+1 redundant configurations add a spare power module so the system keeps supporting full load even if one module is offline for service.

Topology. The Galaxy VX is exclusively online double-conversion. The load is always fed from the inverter, so there is no transfer time on a utility failure and the output is conditioned against sags, surges, and frequency variation. This is the appropriate topology for data centres and other loads that cannot tolerate any break in clean power.

Runtime. Runtime depends on the external battery cabinets paired with the UPS rather than internal batteries. Every model in this series is extended-runtime capable, so battery autonomy is engineered to your facility's ride-through requirement.

Form factor. All Galaxy VX units are free-standing tower (floor-mount) systems intended for a dedicated electrical or UPS room, not rack mounting.

Why the Galaxy VX series

• Online double-conversion with pure sine-wave output for complete load isolation.
• High-efficiency operating modes that reduce energy losses at scale.
• Scalable and N+1 redundant options to match capacity and availability requirements.
• Three-phase 400 V output (with 380 V / 415 V support on several models) for facility distribution.
• External battery support for engineered extended runtime.

Frequently asked questions

What is the power range of the Galaxy VX series?
The Galaxy VX models in this collection span 500 kVA up to 1500 kVA, available as single-module, field-scalable, and N+1 redundant configurations.

Is the Galaxy VX online double-conversion?
Yes. Every Galaxy VX unit is online double-conversion with pure sine-wave output, so the load is always fed from the inverter with no transfer time on a power failure.

Does the Galaxy VX include batteries for runtime?
Runtime is provided by external battery cabinets sized to your facility. All models are extended-runtime capable, so autonomy is engineered to your ride-through target rather than fixed.

Is this a rack-mount UPS?
No. The Galaxy VX is a free-standing tower (floor-mount) system designed for a dedicated electrical or UPS room.

What output voltage does it provide?
The series provides 400 V AC three-phase output, with several models also supporting 380 V and 415 V.
