APC by Schneider Electric GVSUPS40KFS-A 40kW Three-Phase Double-Conversion Tower UPS
Overview
The APC by Schneider Electric GVSUPS40KFS-A is a 40kW (40 kVA) three-phase double-conversion online UPS in a tower form factor, designed for data centers, large server rooms, and critical infrastructure environments where power conditioning and runtime flexibility are non-negotiable. Unlike line-interactive designs, the double-conversion online topology means your connected load is always running from clean, regulated inverter output — the utility feed never reaches the load directly. That matters in environments with chronic power quality issues: voltage sags, spikes, and frequency drift are absorbed by the UPS before they ever reach sensitive equipment.
This specific model is the start-up configuration for external battery cabinets, meaning runtime is determined by however many external battery enclosures you commission alongside it — not a fixed internal pack. If your availability requirements call for 15, 30, or 60+ minutes at full load, you size the battery infrastructure accordingly rather than being locked into whatever the internal option ships with. For mission-critical deployments, that flexibility is significant. Explore the full APC by Schneider Electric power protection catalog for compatible battery enclosures and accessories.
Key Features
- 40kW Double-Conversion Online Architecture: The inverter is always active and always between the utility and the load — no transfer time, no switching transient. For three-phase UPS systems protecting virtualization hosts or broadcast infrastructure, this is the topology that eliminates the last gap that line-interactive designs can't close.
- Flexible Output Voltage (200 / 208 / 220 V AC): Three selectable output voltages let a single unit serve mixed equipment environments without step-down transformers. Whether your PDUs are 200V-rated or your facility is wired for 208V, the GVSUPS40KFS-A adapts rather than forcing a transformer workaround.
- Wide Input Voltage Range (177–239 V AC): The UPS stays on utility power — and off battery — across a 62-volt input swing. In facilities with marginal utility quality, that wider window preserves battery cycle life instead of burning through it on routine brownouts.
- 60 Hz Output at Fixed Frequency: The output frequency is regulated to 60 Hz regardless of input frequency variation. For frequency-sensitive equipment like precision test instruments or synchronous motors, this matters. The input is rated to 70 Hz, providing headroom for utility instability without triggering a fault.
- Sine Wave Output: Pure sine wave output is required for modern active-PFC power supplies and any equipment with motor loads. Simulated or stepped sine wave designs create compatibility problems with active-PFC PSUs — the GVSUPS40KFS-A avoids that entirely.
- External Battery Configuration (Start-Up): Shipped as a start-up unit for external battery integration, this configuration gives you runtime scalability. Commission the UPS battery enclosures you need for your target runtime rather than accepting a fixed internal capacity that may underdeliver in a sustained outage.
- Operating Temperature Up to 104°F (40°C): Rated for environments reaching 40°C — useful in mechanical rooms or non-climate-controlled equipment spaces where cooling is imperfect. That said, battery longevity is temperature-sensitive; external battery cabinets should still be kept as cool as practical.
- Sound Emission at 65 dB(A): At 65 dB(A), this unit is audible in a quiet office space but manageable in a dedicated equipment room or data hall. Plan placement accordingly if noise is a concern in your facility layout.
- Tower Form Factor: The tower orientation — 58.5
