The Eaton 93PS is a modular three-phase online double-conversion UPS for data centres, server rooms and other mission-critical sites, from 8 to 40 kW. It delivers continuous, fully isolated power at unity power factor, runs above 96 percent efficiency in double conversion and up to 99 percent in Energy Saver System mode, and is built to scale: a pay-as-you-grow architecture, hot-swap and hot-scalable modules, and paralleling of up to four units. It is the protection for loads where downtime is measured directly in lost revenue.

What is the 93PS for?

It is for three-phase, larger critical loads: data centres and server rooms, manufacturing and industrial facilities, healthcare, telecom and retail buildings, anywhere the supply is three-phase and the equipment needs continuous, clean power with room to grow. It protects the kind of estate covered by our finance and iGaming infrastructure work. For single-phase loads, the 9PX is the premium choice; for the larger three-phase range, see the 93T.

Key features

Unity power factor. A 1.0 power factor means the full kW is available for its kVA, so you get all the real power the rating promises.

Up to 99% efficiency. Above 96 percent in double conversion and up to 99 percent in Energy Saver System mode, which cuts running cost and heat over the life of the system.

Scalable, pay as you grow. Add capacity in steps as the load grows, hot-scale modules without dropping the load, and parallel up to four units with HotSync technology.

Serviceable and resilient. Hot-swap modules, internal and external maintenance bypass, and external battery cabinets, so the system can be maintained and the runtime sized without taking the load down.

Technical specifications

Which Eaton UPS is right for you?

The 93PS is the modular three-phase choice for data-centre and critical loads up to 40 kW. For larger three-phase systems, the 93T runs to 80 kVA with an internal battery option. For single-phase server rooms, the 9PX and 9SX are the units to consider. A three-phase system is an engineered installation, so we design it to your load, runtime and growth; our UPS and power protection hub and sizing guide set out the approach.

Frequently asked questions

How efficient is the 93PS?

Above 96 percent in double-conversion mode and up to 99 percent in Energy Saver System mode, which lowers running cost and heat.

Can it grow with our load?

Yes. Its pay-as-you-grow architecture lets you add capacity in steps, hot-scale modules without dropping the load, and parallel up to four units.

Is it serviceable without downtime?

Yes. Modules are hot-swappable, with internal and external maintenance bypass, so the system can be serviced while it keeps protecting the load.
