APC by Schneider Electric GVSUPS20KRHS Galaxy VS 20KW Tower UPS with N+1 Power Module

Overview

The GVSUPS20KRHS is APC's Galaxy VS three-phase tower UPS rated at 20KW/400V, designed for data centers, server rooms, and critical infrastructure environments that need scalable, modular power protection with a lithium-ion battery architecture. The N+1 power module configuration means one redundant power module is built into the design — if an active module fails, the redundant module picks up the load without dropping critical systems. Unlike lead-acid alternatives, the Li-Ion battery technology reduces footprint and extends service intervals, which matters in environments where access time and maintenance windows are constrained.

Key Features

• 20KW at 400V Three-Phase Output: Sized for mid-range data hall rows, edge compute nodes, or consolidated server racks where single-phase UPS units fall short. At 20KW, this unit can carry a meaningful portion of a rack-dense aisle without requiring multiple smaller units and the associated overhead of parallel management.
• N+1 Power Module Architecture: The N+1 redundancy means one extra power module beyond what the load requires is always present. In practice, this allows hot-swap module replacement during a live event — a failure doesn't become an outage, and you don't have to schedule an emergency maintenance window at 2AM to swap hardware.
• Lithium-Ion Battery Technology: Li-Ion cells are lighter than equivalent lead-acid capacity, tolerate higher operating temperatures without accelerated degradation, and typically support a longer service life before replacement. For installations where battery replacement logistics are complex — raised floor data centers, remote edge sites, secure facilities — that extended cycle life reduces operational burden. This model is specifically designed for external battery cabinets, giving you flexibility to scale runtime without replacing the UPS itself.
• External Battery Design: Runtime is determined by external battery strings rather than internal cells, which means you can right-size the battery investment for the actual runtime target — whether that's 10 minutes to cover a generator start or 60+ minutes for a prolonged utility event. It also means battery maintenance can occur without taking the UPS offline if your configuration supports bypass.
• Tower Form Factor — 512mm W × 847mm D × 1485mm H: The tower footprint (512mm wide, 847mm deep, 1485mm tall) fits in a standard server room floor position without requiring a raised floor or dedicated rack bay. At these dimensions, verify floor loading capacity and aisle clearance before installation — a loaded 20KW UPS with external battery cabinets is a significant weight concentration.
• Operating Temperature Range 0–40°C: The 0–40°C operating envelope is standard for commercial data center environments. If your site runs hot — edge deployments in non-climate-controlled spaces, industrial environments, or telecom huts pushing 45°C — this unit is not the right fit without supplemental cooling. The 0°C lower bound also means cold-aisle containment configurations near 10°C are fine.
• Operating Humidity 0–95% (Non-Condensing): A wide humidity tolerance that accommodates most commercial building environments and standard data center humidity ranges without requiring active dehumidification below the device's tolerance floor.
• Operating Altitude up to 1,005m: Rated to approximately 1,000 meters above sea level at full load. Above this threshold, derating may apply — relevant if deploying at high-altitude facilities (Denver, mountain-region edge sites, highland telecom shelters).
• RoHS Compliance: Meets RoHS (Restriction of Hazardous Substances) requirements, which matters for procurement in regulated industries and for facilities with environmental compliance requirements tied to equipment sourcing.
• Sustainability Compliance Certified: APC documents sustainability compliance for this SKU, relevant for enterprise and public-sector buyers with green procurement mandates or ESG reporting requirements.

Integration and Compatibility

The GVSUPS20KRHS is designed to work with APC Galaxy VS external battery cabinets — sizing runtime requires matching the external battery strings to your load and target backup duration. This UPS is not a standalone runtime device; plan the battery cabinet selection alongside the UPS order. For larger deployments, review network infrastructure power planning to ensure switch and server loads are accurately tallied before sizing. APC Galaxy VS units typically integrate with EcoStruxure IT and DCIM platforms for monitoring and alerting — confirm software compatibility with your management platform before deployment. For full data center power protection planning, consult UPS selection resources covering load calculation, runtime curves, and battery sizing.

Frequently Asked Questions

Q: Does the GVSUPS20KRHS include internal batteries?

A: No. The GVSUPS20KRHS is specifically configured for external batteries. Runtime depends on external battery cabinet selection — battery cabinets must be ordered separately and sized to match your load and target runtime.

Q: What is the N+1 power module on the GVSUPS20KRHS?

A: N+1 means one redundant power module is present beyond what is needed to support the full rated load. If one active module fails, the redundant module assumes the load without interruption, allowing the failed module to be replaced without an outage.

Q: What battery type does the GVSUPS20KRHS use?

A: The GVSUPS20KRHS uses Lithium-Ion (Li-Ion) battery technology, which offers a longer service life and higher temperature tolerance compared to traditional VRLA lead-acid alternatives used in many UPS systems.

Q: What is the maximum operating temperature for the GVSUPS20KRHS?

A: The GVSUPS20KRHS is rated for operation between 0°C and 40°C. Environments exceeding 40°C may require supplemental cooling or derating, and this unit should not be deployed in uncontrolled industrial or outdoor environments without appropriate conditioning.

Q: Is the GVSUPS20KRHS RoHS compliant?

A: Yes. The GVSUPS20KRHS carries RoHS compliance certification, making it suitable for procurement in regions and industries with hazardous substance restrictions on electrical equipment.

Q: What are the physical dimensions of the GVSUPS20KRHS?

A: The GVSUPS20KRHS tower measures 512mm wide, 847mm deep, and 1,485mm tall. Verify floor load ratings and aisle clearance before installation, particularly when paired with external battery cabinets which add additional weight and footprint.
