Eaton 93PM G2 (EMEA) / 93PM 480V (North America)

Eaton's second-generation modular UPS, sold as 93PM G2 in EMEA and as 93PM 480V in North America

Eaton 93PM G2 (EMEA) / 93PM 480V (North America) is one of 22 UPS systems tracked in the SecondWatt catalogue, each with specifications, lead times and indicative secondary-market pricing.

Eaton 93PM G2 dossier: 50 kW hot-swap modules to 360 kVA, 99% Energy Saver efficiency, SLEP modernization, used pricing near 360 USD per kW, inspection tips.

The 93PM G2 is the second generation of Eaton's 93PM modular UPS, announced in October 2020 and built from hot-swappable 50 kW power modules. One naming point governs any listing: G2 is the EMEA and international designation. It resolves on Eaton's GB, Kenya, UAE, Lithuania and Nigeria sites but not on the Eaton US 93PM family page, which lists only 93PM 208V and 93PM 480V. The US product is G2-generation hardware sold without the G2 name, so a dossier under this title has to carry both spec sets. The EMEA machine runs 50-300 kW at unity power factor or 60-360 kVA at 0.9, on 220/380 to 240/415 V, with up to 97% double conversion and above 99% in Energy Saver System. The US 480 V machine covers 50, 100, 150, 200 and 250 kW with optional internal N+1 through 200 kW inside a 250 kW frame, carries UL 1778 and cULus listings, and supports lithium-ion battery systems. Both parallel four ways. The most important question on any used 93PM is not age but whether the service life extension program has been run. Eaton's SLEP targets units ten years and older, replacing power modules, DC capacitors, static switch, fans and the communications server board inside the existing shell in roughly 24 hours with no electrical re-installation, resetting another ten years and optionally adding the 99% Energy Saver upgrade. Ask for the SLEP record before pricing.

Who buys it

Data center and enterprise operators in the 50 to 360 kVA band, and the large installed base buying spare 50 kW power modules.

Role in the data center

Primary modular UPS for enterprise and mid-size data halls, configured N+1 inside a single frame and paralleled up to four ways for larger blocks.

Technical summary

EMEA ratings: 50-300 kW at unity PF; 60-360 kVA at 0.9 PF US ratings: 50, 100, 150, 200, 250 kW at 480 V with internal N+1 to 200 kW Power module: 50 kW / 60 kVA, hot-swappable Efficiency: up to 97% double conversion; above 99% in Energy Saver System Topology: transformer-free IGBT with PWM, online double conversion, modular Parallel: up to 4 units US footprint: 74 in H x 42 in D x 22 in W EMEA footprint: 800 x 990 x 1987 mm; 361-576 kg by module count; IP20 Battery: VRLA 384-528 V (32-44 blocks); also lithium-ion, NiCd, wet cell, supercapacitors Standards: UL 1778 and cULus on the US build; IEC 62040-1, 62040-2, 62040-3 on the EMEA build

Pricing and availability

Comparable secondary-market band: 35999.99–36500 $ per unit. Trend: up Lead time, new: 20-32 weeks (100-500 kVA class benchmark); Eaton is allocating rather than repricing. Lead time, used or refurbished: 1-4 weeks from dealer stock. Warranty, used: 1-year typical from refurbishment dealers.

Lifecycle and maintenance

Modular UPS frames outlive their modules: cabinet, bus and static bypass run 15 years or more while the hot-swap power modules carry the fans and DC capacitors that wear. That moves the maintenance question from cabinet age to module hours and module count, since a 1,500 kW ABB DPA system holds 30 module-level fan and capacitor sets. Eaton's 93PM service life extension program replaces power modules, DC capacitors, static switch, fans and the communications board inside the existing shell in about 24 hours, resetting another 10 years. Ask whether that program has been run before pricing any 10-year-old modular frame.

Common failure points

• Power module population — A frame sold on nameplate ships with fewer modules than the rating implies
• Module fans and capacitors — Consumables sit inside each module, so wear scales with module count not cabinet count
• Battery strings — VRLA capacity fades below 80% of nameplate and takes the ride-through with it
• Missing filler plates — Open slots break the cooling path and signal careless handling
• Live Swap entitlement — A frame without the Live Swap label must be bypassed for any module work
• Controls obsolescence — Controller and display boards reach end of life ahead of the power train

Inspection checklist

Module count — count populated slots against the frame rating; Eaton lists a 4 kVA 9PXM power module at 4,377 USD Filler plates — Schneider's manual requires a module or filler plate in every slot on a 50 kW module bay Module consumables — fans and capacitors live inside each module; a 1,500 kW DPA system carries 30 such sets Live Swap label — verify the physical label; a Galaxy VS or VL without it must be bypassed, at 200 mm standoff Module part numbers — confirm interchange; Schneider GVPM50KD is 50 kW at 400/480 V and 25 kW at 208 V 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 DC bus capacitors — Eaton rates 7 years of continuous duty and up to 10 under favorable conditions Cooling fans — Vertiv field data gives 5-6 years or 40,000-50,000 hours of operation before replacement Static bypass — transfer to bypass and back under load 3 times; verify each module's own bypass path where fitted Parallel kit — verify the parallel hardware and unit count; these frames commonly parallel 4 to 8 ways Firmware — verify the controller revision and card slots; Eaton's 11-point guidance makes firmware access a condition Lifecycle stage — confirm OEM support status; Mitsubishi's 4-stage lifecycle table is the only dated public one Rigging — verify path and lift plan; an ABB DPA 250 S4 frame runs 345-667 kg once populated with modules

Procurement channels

CI Group and eBay specialist dealers carry refurbished and new-surplus 93PM frames and battery cabinets, often as separate stock numbers. Eaton also runs the category's only factory-certified refurbished program, with factory-technician testing, onsite startup and a one-year warranty.

Regional notes

The G2 name is EMEA and international. North American buyers purchase 93PM 208V or 93PM 480V, which is the same hardware generation with UL 1778 and cULus listings and a different rating table.
