ABB MegaFlex DPA (IEC) and MegaFlex UL (North America)

ABB's megawatt-class modular UPS, extended to 2,000 kW in March 2026 and the only ABB line trading used

ABB MegaFlex DPA (IEC) and MegaFlex UL (North America) is one of 22 UPS systems tracked in the SecondWatt catalogue, each with specifications, lead times and indicative secondary-market pricing.

ABB MegaFlex DPA (IEC) and MegaFlex UL (North America) ups — specifications, pricing tiers, and availability on SecondWatt.

Who buys it

Hyperscale, colocation and neocloud data center developers buying megawatt UPS blocks, and the engineering firms specifying them. On the secondary side the buyer is a developer willing to underwrite an unverified open-box asset against a 40 to 60 week new-equipment queue for modular UPS above 2,000 kVA, and to fund startup and commissioning independently.

Role in the data center

Megawatt-class primary UPS for hyperscale and colocation halls, configured N+1, 2N, 2N+1, N+N or distributed-redundant catcher, with an external lithium-ion or VRLA plant.

Key specifications

Technical summary

MegaFlex DPA range: 250-1,500 kW, extended to 1,000-2,000 kW in March 2026 Module: 250 kW slide-in, online-swappable, automatic isolation on fault Efficiency (DPA): 96.5% at full load, 97.4% at half load; 99% eco; 97.6% VFI on the 2026 range MegaFlex UL ratings: 1000-1350 kW at 415 V; 1000-1600 kW at 480 V MegaFlex UL modules: 337 kW at 415 V; 400 kW at 480 V MegaFlex UL efficiency: up to 97% double conversion; up to 99% in eBoost Dimensions (1,500 kW DPA): 3045 x 2000 x 1000 mm, 3,250 kg; noise 78 dBA Battery: external only, 480-600 V; lithium-ion, VRLA, VLA, NiCd, nickel-zinc Design life: 15 years Standards: UL 1778 and UL 9540 on the UL variant; EN 62040-1; EMC class C3

Pricing and availability

Comparable secondary-market band: 620–1589 $ per kVA. Trend: up Lead time, new: 40-60 weeks (modular UPS above 2,000 kVA, class benchmark). Lead time, used or refurbished: 1-4 weeks where open-box stock exists. 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

New units through ABB and its authorized channel, quote-only in North America. The one secondary unit located came through a general surplus reseller rather than a power-equipment dealer, which is itself the diligence warning.

Regional notes

A US buyer purchases MegaFlex UL, not MegaFlex DPA. Both names appear in ABB's global systems index and only the UL variant is tested to UL 1778 and UL 9540.
