Schneider Electric’s Galaxy series covers the full range of three-phase power protection, from 10 kVA deployments to 1,500 kVA hyperscale installations.
All three models operate in double-conversion (VFI) mode, support both VRLA and lithium-ion battery configurations, and integrate with Schneider Electric’s EcoStruxure IT platform for remote monitoring. Here’s a quick look at where each fits.
Product Summary: Model, Power Range and Application
- Galaxy VS: 10-150 kVA (208V or 480V), Modular three-phase UPS for medium-density IT and critical facilities. Hot-swap power modules; supports internal N+1.
- Galaxy VL: 200–500 kVA/kW, Scalable, redundant architecture for large data centers. Add capacity without replacing the base frame.
- Galaxy VX: 500–1,500 kVA, Enterprise and hyperscale data centers. Multiple operating modes including ECOnversion (up to 99% efficiency).
Features: What Drives Most Galaxy Specifications
- Double-conversion (VFI): Zero transfer time to battery. The output is continuously inverter- derived — complete isolation from utility voltage and frequency variations.
- Modular architecture: Hot-swap power modules on the VS; frame-level scalability on the VL and VX. Add capacity without replacing the base system.
- ECOnversion mode (VX): Up to 99% efficient while keeping the inverter active and synchronized — unlike standard bypass/ECO modes.
- EcoStruxure IT integration: Remote monitoring, event logging, and predictive maintenance alerts across all Galaxy installations.
Battery Option: VRLA or Lithium-Ion (VS, VL & VX) – The Case for Li-Ion
- Service life: 8–10 years vs. 3–5 for VRLA
- Up to 50% smaller and lighter footprint
- Integrated BMS monitors cell health continuously — no periodic discharge testing required
- Recharges to 90% in 2–4 hours vs. 8–12 hours for VRLA
