APC Galaxy VS 20kW Modular 3-Phase UPS

The APC Galaxy VS 20kW Modular 3-Phase UPS (GVSUPS20KB2) from Schneider Electric is a scalable, modular uninterruptible power supply engineered for mid-size data centers and distributed IT environments demanding high availability and operational efficiency. Built on a true online double-conversion architecture, the Galaxy VS delivers continuous clean power by isolating connected loads from all incoming power anomalies including sags, surges, harmonics, and complete outages. The modular design enables power capacity to be scaled incrementally without system downtime, reducing stranded capital and allowing IT infrastructure teams to align power investments directly with actual load growth.

The Galaxy VS 20kW model ships with a 20kW power module installed and supports field-upgradeable capacity expansion within the same chassis, a principle that minimizes rack footprint while future-proofing the installation. Operating at up to 96% efficiency in online double-conversion mode and reaching up to 99% in Energy Saver System (ESS) mode, the unit significantly reduces heat output and ongoing energy expenditure compared to previous-generation UPS platforms. Integrated lithium-ion battery compatibility is supported alongside traditional VRLA options, offering operators flexibility in battery strategy, total weight reduction, and extended service life.

Designed for three-phase input and output at 400V, the Galaxy VS 20kW integrates advanced monitoring and management through Schneider Electric's EcoStruxure IT ecosystem, enabling remote supervision, predictive alerts, and lifecycle management from a centralized dashboard. Its compatibility with network management cards facilitates SNMP and Modbus communications for seamless integration into enterprise building management and DCIM platforms. The unit is well suited for edge data centers, server rooms, and modular prefabricated data hall deployments where right-sizing, serviceability, and efficiency are primary operational requirements.

Ideal for

• Mid-size enterprise data center power protection requiring scalable UPS capacity without planned downtime during expansion
• Edge computing installations and distributed IT closets where compact footprint and remote manageability via EcoStruxure IT are essential
• Healthcare IT infrastructure supporting electronic medical record systems and clinical applications that demand continuous, conditioned power
• Financial services server rooms requiring high availability, low total harmonic distortion, and auditable power event logging
• Modular or prefabricated data center deployments where the UPS must be commissioned quickly and expanded in line with phased build-outs
• Industrial control and process automation environments operating on three-phase 400V infrastructure that require protection from grid instability
