APC by Schneider Electric GVSUPS20KB2GS Galaxy VS 20kVA 480V Double-Conversion Tower UPS

Overview

The APC by Schneider Electric Galaxy VS (GVSUPS20KB2GS) is a three-phase, double-conversion online UPS rated at 20kVA/20kW at 480V — purpose-built for edge deployments, small-to-medium data centers, and critical infrastructure in commercial and industrial facilities where a power outage or voltage irregularity is not a recoverable event. At 540 lb in a tower form factor measuring 58.5" H × 13.1" W × 33.4" D, this is a system you plan around, not an afterthought purchase. The Galaxy VS scales across a broad kW range (20–100kW at 480V), so the GVSUPS20KB2GS sits at the entry point of a modular family — an important buying consideration if your load is expected to grow.

Key Features

• Double-Conversion Online Architecture: Unlike standby or line-interactive designs, the Galaxy VS continuously regenerates clean AC power — your connected loads never see raw utility power at all. Every spike, sag, harmonic distortion, and frequency deviation is blocked at the input. For servers, network equipment, or any load with a zero-transfer-time requirement, this is the architecture that matters.
• 97% Efficiency (Normal Mode) / 99% in ECOnversion Mode: Efficiency translates directly to your operating cost. At 97%, the Galaxy VS loses roughly 600W as heat at full 20kW load — far less than older-generation double-conversion systems that typically run 90–94%. ECOnversion mode pushes to 99%, equivalent to 66% higher energy savings per the manufacturer, which meaningfully reduces both power draw and cooling demand in densely loaded edge closets or small data rooms.
• N+1 Redundancy and Fault-Tolerant Architecture: The Galaxy VS is engineered with modular power modules that support N+1 internal redundancy. A single power module failure doesn't bring the system down — critical for any deployment where maintenance windows are infrequent or planned downtime is unacceptable.
• Smart Modular Batteries (Lead Acid, Integrated in Cabinet): Battery modules integrate directly inside the UPS cabinet rather than requiring external battery enclosures. This limits the physical footprint, simplifies your floorplan, and — critically — provides highly predictable runtimes because the battery configuration is a defined, controlled variable rather than an estimate from external strings. Lead acid chemistry is a proven, maintenance-familiar choice for facilities teams.
• EcoStruxure Ready: The included Integrated Network Management card connects the Galaxy VS to Schneider Electric's EcoStruxure platform, enabling remote monitoring, predictive maintenance alerts, and centralized power management visibility. For facilities with an existing EcoStruxure or data center infrastructure management (DCIM) deployment, this means the UPS reports into your existing management stack rather than requiring a separate monitoring tool.
• RoHS Compliant: The Galaxy VS carries RoHS environmental certification, relevant for deployments in regions with strict hazardous materials regulations or for enterprise customers with environmental procurement policies.
• Start-Up Service Included: A factory start-up service is bundled with the GVSUPS20KB2GS. This is not a trivial addition — on a 540 lb, 20kW three-phase system, proper commissioning directly affects warranty validity and system performance. Having professional commissioning included means one fewer line item in the project budget and one fewer coordination task for the installing contractor.
• Top and Bottom Cable Entry: Dual cable entry options accommodate different installation scenarios — bottom entry for raised-floor or under-floor conduit runs, top entry for overhead cable trays or ceiling drops. This flexibility reduces field modification time during installation in environments where the conduit path is constrained.

Integration and Compatibility

The Galaxy VS operates on 480V three-phase input at the 20kW tier, which limits compatibility to facilities with three-phase electrical infrastructure at that voltage — verify your electrical panel capacity and breaker sizing before specifying this unit. The system supports three-phase UPS deployments from edge closets through mid-scale data rooms. The included Integrated Network Management module provides SNMP and network-based management integration, which aligns with most enterprise network management systems and DCIM platforms. For organizations evaluating full power chain coverage, pairing this UPS with compatible rack PDUs and a structured UPS and power planning guide will help size upstream capacity correctly. The Galaxy VS is EcoStruxure Ready for organizations running Schneider Electric's management ecosystem.

Frequently Asked Questions

Q: What is the output capacity of the GVSUPS20KB2GS and what voltage does it require?

A: The GVSUPS20KB2GS is rated at 20kVA/20kW and operates at 480V three-phase input. This is not a single-phase unit — your facility must have three-phase 480V electrical infrastructure to support it.

Q: What type of UPS topology does the Galaxy VS use?

A: The Galaxy VS uses double-conversion online topology, also described as dual-conversion. In this mode, incoming AC is continuously converted to DC and back to AC, meaning connected loads are fully isolated from utility power at all times — eliminating transfer time on power events.

Q: What is the warranty on the GVSUPS20KB2GS?

A: APC by Schneider Electric provides a 1-year limited warranty on the GVSUPS20KB2GS. A factory start-up service is included with the unit, which is required for proper commissioning of the system.

Q: Does the Galaxy VS include network management capability?

A: Yes. The GVSUPS20KB2GS ships with an Integrated Network Management card included in the box, enabling remote monitoring, SNMP integration, and EcoStruxure platform connectivity out of the box — no separate network management card purchase required.

Q: Can the Galaxy VS scale beyond 20kW?

A: The Galaxy VS product line scales from 20kW up to 100kW at 480V. The GVSUPS20KB2GS is the 20kW entry point of this family, so if load growth is anticipated, the Galaxy VS platform supports expansion within the same product architecture.

Q: How heavy is the GVSUPS20KB2GS and what are its physical dimensions?

A: The unit weighs approximately 540 lb and measures 58.5" H × 13.1" W × 33.4" D. Floor reinforcement and rigging capability should be verified before installation — this is not a unit that can be repositioned without proper equipment.

Marty Allison

The GVSUPS20KB2GS is the kind of unit I specify when a customer has a hard requirement for zero transfer time and three-phase 480V infrastructure already in place. The double-conversion topology and 97% normal-mode efficiency are the two numbers I lead with — at 20kW, running 24/7, that efficiency delta versus an older 92% system represents real kilowatt-hours and real dollars on the annual utility bill. This isn't a spec to gloss over.

Technical Highlights:

• 97% / 99% Efficiency: At 20kW full load, the 97% normal-mode figure means roughly 600W of loss as heat versus 1,600W on a 92% unit — a meaningful cooling load reduction in tight edge deployments. ECOnversion mode at 99% is the right choice where utility power quality is consistently good and you want maximum energy savings.
• Integrated Smart Modular Batteries: Batteries housed inside the cabinet — not in external strings — means runtime is a calculated, predictable number rather than an estimate. For compliance-driven data center environments where runtime documentation is part of the BCP, this matters.
• N+1 Redundancy via Modular Power Modules: A single module failure does not interrupt load. For small data centers running without a second UPS in parallel, this internal redundancy is the risk mitigation that makes the Galaxy VS architecture defensible in a design review.

Deployment Considerations:

• At 540 lb and 58.5" tall, rigging and floor load capacity are non-negotiable pre-installation checks. Confirm your floor rating before committing to a location — repositioning this unit after the fact is a project in itself.
• The 1-year limited warranty is shorter than some competing three-phase UPS products at this price tier. Budget for an extended service agreement if your operational requirements demand longer coverage, and confirm commissioning through the included start-up service to keep the warranty valid from day one.

The GVSUPS20KB2GS is well-positioned for edge data rooms in manufacturing facilities, small colocation pods, or any commercial deployment running three-phase 480V where the combination of high efficiency, internal redundancy, and integrated network management needs to fit in a single tower footprint without external battery cabinets consuming additional floor space.
