The Eaton 93T is a three-phase online double-conversion UPS for larger mission-critical sites, from 15 to 80 kVA. It delivers continuous, fully isolated power at unity power factor, runs above 96 percent efficiency in online mode and up to 99 percent in Energy Saver mode, and offers an internal battery option up to 80 kVA, which keeps the footprint smaller than systems that need external cabinets. It is the three-phase unit for industrial and enterprise loads that need dependable power and room to scale.

What is the 93T for?

It is for larger three-phase critical loads, industrial facilities, larger data centres and enterprise plant rooms, where the supply is three-phase and the load runs from tens of kVA upward. With an internal battery available up to 80 kVA, it suits sites that want a self-contained system rather than separate battery cabinets, and it scales by paralleling up to four units. For loads up to 40 kW where modular pay-as-you-grow matters, the 93PS is the alternative; for single-phase, the 9PX.

Key features

Unity power factor. A 1.0 power factor provides more real power than legacy designs for the same kVA rating.

High efficiency. Above 96 percent in online mode and up to 99 percent in Energy Saver mode, reducing running cost and heat at scale.

Internal battery option. An internal battery available up to 80 kVA keeps the system compact, without the floor space of external cabinets.

Scalable and managed. Parallel up to four units, with Advanced Battery Management for intelligent charging and long battery life.
