Eaton Power Xpert 9395P, 200-1200 kVA

Eaton's megawatt-class UPS with 99% Energy Saver efficiency, still in full production with no assigned end-of-life date

Eaton Power Xpert 9395P, 200-1200 kVA is one of 22 UPS systems tracked in the SecondWatt catalogue, each with specifications, lead times and indicative secondary-market pricing.

Eaton Power Xpert 9395P dossier: 200-1200 kVA, 99% Energy Saver efficiency, 600 V option, lead-time arbitrage against the used 9395, plus inspection tips.

Why it matters

The 600 V premium option is a quiet capex argument that rarely gets priced. Taking the UPS to 600 V removes an external transformer from the one-line, which removes both its cost and its lead time in a market where distribution transformers run far longer queues than the UPS itself. Efficiency drops to 96% at 600 V from 97% at 480 V, so the trade is a point of efficiency against a piece of equipment.

Who buys it

Large data center, healthcare and industrial buyers specifying 200 kVA to 1.2 MW of conditioned power, and integrators assembling multi-megawatt parallel systems. On the secondary side the practical buyer is shopping the predecessor 9395, where used inventory ships in one to two weeks against 20 or more weeks for a new 9395P.

Role in the data center

Megawatt-class primary UPS for large data halls and hospital campuses, paralleled to eight units through a System Bypass Module, with an external battery plant.

Pricing and availability

Trend: up Lead time, new: 20+ weeks at 500 and 1200 kVA (dealer published). Lead time, used or refurbished: 1-2 weeks on the predecessor 9395. 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

Procurement channels

Global Power Supply, Mission Critical Facilities International and CI Group hold new 9395P and used 9395 stock, plus 9395 rental units. Battery cabinets are consistently separate stock numbers, so any quote has to state battery inclusion explicitly.

Regional notes

US builds are UL 1778 and cUL listed at 480, 400 and 600 V. The EMEA technical specification covers 220/380 to 240/415 V and publishes the VFI-SS-111 class string the US pages omit.
