APC Galaxy VS 20kVA 20kW 400V 3-Phase UPS (GVSUPS20KHS) | Without Internal Battery

The APC Galaxy VS 20kVA (GVSUPS20KHS) is a highly efficient, modular, and compact 3-phase uninterruptible power supply (UPS) designed to meet the critical power requirements of edge, small, and medium data centers. This model delivers 20kW of real power (PF=1.0) in a remarkably small footprint. As a “Without Internal Battery” version, the GVSUPS20KHS is optimized for use with external battery solutions (including Lithium-ion), providing maximum flexibility for scalable backup runtimes. With its patented ECOnversion™ technology, it achieves up to 99% efficiency, significantly reducing your total cost of ownership (TCO).

Key Functions and Features

World-Class Efficiency (ECOnversion™): Achieves up to 99% efficiency in ECOnversion mode, providing Class 1 compliant power protection while drastically lowering electricity and cooling costs.

Compact Footprint: The Galaxy VS is known for its high-density design, making it ideal for confined spaces and edge computing environments where every square centimeter counts.

Unity Power Factor (kVA=kW): Provides 20kW of real power, ensuring you get the most out of your UPS investment without the need for derating when powering modern IT loads.

Flexible Battery Storage: Compatible with traditional VRLA batteries as well as high-performance Lithium-ion battery cabinets, which offer longer service life and reduced weight.

Modular & Serviceable Design: Features a modular architecture for quick serviceability and front-access maintenance, minimizing the Mean Time to Repair (MTTR).

EcoStruxure™ Connected: Integrated with Schneider Electric’s cloud-based management platform, allowing for 24/7 remote monitoring and smartphone-based status alerts.

Frequently Asked Questions (FAQ)

Q1: What is the benefit of the GVSUPS20KHS “Without Battery” model?

A: This model provides the flexibility to customize your backup runtime by using external battery cabinets. It is especially beneficial for users who prefer long-duration backup or high-performance Lithium-ion battery technology.

Q2: How much can I save with ECOnversion mode?

A: ECOnversion mode provides up to 99% efficiency. For a 20kW load, this can save thousands of dollars in energy costs over the lifespan of the UPS compared to traditional 94% efficient units.

Q3: Is the Galaxy VS 20kVA compatible with 3-phase input and output?

A: Yes, the GVSUPS20KHS is a 3:3 phase system, supporting 3-phase 400V input and providing 3-phase 400V output for balanced industrial and IT loads.

Q4: Can I manage this UPS remotely?

A: Absolutely. It comes with built-in network management and is fully compatible with the EcoStruxure™ IT suite for real-time remote monitoring and smartphone alerts.

Q5: What does PF=1.0 mean for my equipment?

A: A Power Factor of 1.0 means that the kVA rating equals the kW rating (20kVA = 20kW). This allows the UPS to support more modern IT equipment that utilizes active power factor correction.
