Schneider Electric Galaxy VX, 500-1500 kVA

Schneider's megawatt-class UPS, still commercialized but one end-of-life bulletin away from a service-life clock

Schneider Electric Galaxy VX, 500-1500 kVA is one of 22 UPS systems tracked in the SecondWatt catalogue, each with specifications, lead times and indicative secondary-market pricing.

Schneider Electric Galaxy VX dossier: 500-1500 kVA, 96.5% double conversion, VXL succession, end-of-life watch items, and a used-unit inspection checklist.

Why it matters

The VX end-of-life bulletin is the single most valuable watch item in the Schneider line. Schneider's pattern is roughly a ten-year service tail after discontinuation, with Galaxy VM and Symmetra PX 250/500 both discontinued in September 2025 and covered to 2035. The precedent that matters more is Galaxy 5000, discontinued 2021 with end of service life in 2031 and no modernization path at all, which is what destroys residual value rather than the discontinuation itself.

Who buys it

Large data center, healthcare and industrial buyers specifying 500 kVA to 1.5 MW of conditioned power, usually as part of an engineered project rather than a stocked purchase. No secondary buyer profile exists yet, because no used VX has reached a public channel.

Role in the data center

Building-scale primary UPS for large data halls and campuses, specified as part of an engineered project with an external VRLA or lithium-ion battery plant.

Key specifications

Technical summary

Rating range: 500-1500 kVA/kW, three-phase Configuration: N+1 redundant SKUs available, for example a 1250 kVA frame delivering 1000 kVA N+1 Double conversion efficiency: 96.5% maximum, the figure Schneider states the VXL surpasses eConversion: up to about 99% while keeping the inverter active Footprint: 4.5 square metres, Schneider's own comparison basis for the VXL Topology: frame-level scalability rather than hot-swap power modules Voltage options: 400 V and 480 V SKU families Battery: external only at this scale; VRLA and lithium-ion supported Live Swap: not documented for the VX; the capability is published for VS, VL and VXL only Lifecycle status: commercialized, with no published end-of-life bulletin located

Pricing and availability

Trend: up Lead time, new: 30-48 weeks (static UPS 500-1500 kVA class benchmark). Warranty, used: 1-year typical from refurbishment dealers.

Lifecycle and maintenance

Static UPS cabinets serve roughly 15 years, the figure Mitsubishi publishes directly alongside a lifecycle-parts-or-replace decision at 10-12 years. The wear items are documented: Eaton rates DC bus capacitors at 7 years of continuous duty and up to 10 under favorable conditions, while Vertiv field data gives 6 years for capacitors and 5-6 years or 40,000-50,000 hours for cooling fans. Batteries turn over far faster, at 3-5 years for sealed VRLA and 12-15 for flooded cells. Service life extension programs rebuild the power train inside the original shell, which is why cabinets routinely outlive their electronics.

Common failure points

• Battery strings — VRLA capacity fades below 80% of nameplate and takes the ride-through with it
• DC bus capacitors — Silent open-circuit loss, or a short that pops and sprays electrolyte across adjacent boards
• Cooling fans — Overheating transfers the load to bypass and leaves it unprotected
• Air filters and dust — Restricted airflow raises internal temperature and shortens capacitor life
• Static bypass switch — Failure to transfer strands the load during maintenance or overload
• Controls obsolescence — Discontinued display and logic boards turn a routine repair into a scavenger hunt

Inspection checklist

Battery age — sealed VRLA turns over at 3-5 years per Eaton lifecycle guidance; assume a full string past that Battery capacity — reject any string below 80% of nameplate capacity under IEEE 1188 practice Battery impedance — ohmic readings above 20% of the commissioning baseline condemn the cell Float voltage — verify 2.23-2.27 VPC at 25 degrees C; float current above 3x steady state flags thermal runaway Intercell connectors — thermal image every joint; a delta above 5 degrees C against neighbors triggers a capacity test DC bus capacitors — Eaton rates 7 years of continuous duty (10 optimal); Vertiv field data gives 6 years at 45,000-50,000 h Cooling fans — Vertiv field data gives 5-6 years or 40,000-50,000 hours; listen for bearing noise at the intake Air filters — pull every filter; a clogged element is the best single proxy for a cabinet that ran above 25 degrees C Load bank test — run 100% and 50% load bank steps; load banking is the de facto acceptance standard in this channel Static bypass — transfer to bypass and back under load 3 times; verify the SCR assembly and breaker interlocks Battery inclusion — get cells, cabinets and racks in writing; a battery package can reach 76% of a 30 kVA class deal Firmware and cards — verify current firmware and a working network card per Eaton's 11-point used-UPS guidance Lifecycle stage — check OEM support status; Mitsubishi's 4-stage table is the only dated public one in the category Documentation — manual, factory startup report and service history; Eaton flags 7-10 year units for capacitor work Removal conditions — verify rigging path, door widths and shutdown window; a 225 kVA cabinet runs 3,605-4,805 lb

Regional notes

Sold under both Schneider Electric and APC by Schneider Electric branding, in 400 V and 480 V SKU families. Regional variance in parts support is real: a UK dealer describes the legacy Galaxy 5500 as obsolete while US end-of-service-life dates run later.
