Eaton 93PM and 93PM G2: 30 to 400 kW three-phase UPS
The Eaton 93PM is a three-phase transformerless UPS covering 30 to 400 kW, with the G2 generation continuing the same platform. It sits one class above the modular edge units and one class below the megawatt frames, which is the band most enterprise data halls actually occupy. We quote it where the load is committed and the room needs density rather than incremental growth.

Battery arrangement and runtime
The 93PM works with a VRLA string at either 432 V, built from 36 blocks of 12 V, or 480 V, built from 40 blocks. Eaton is explicit that strings at different voltages must not be paralleled, so this decision is made once and it constrains every later expansion. Charging current is set by the frame rather than by the battery. The datasheet gives 22 A on the 30 to 50 kW frame, 44 A on 80 to 100 kW, 66 A on 120 to 150 kW and 88 A on 160 to 200 kW. That figure decides how quickly you are protected again after a long outage, and it is the number to check on a site that suffers repeated short interruptions rather than one long one. Charging follows either ABM management or a conventional float regime, and temperature compensation is an option rather than a default. Tell us the runtime you need and whether a generator is present. A site with a generator usually needs minutes; a site without one needs a different battery plan altogether.
Source of the values: Eaton 93PM UPS 30-200 kW datasheet (93PM01DAT Rev F) + 30-50 kW datasheet (Rev C). The family is offered from 30 kW to 400 kW; the rows above are the ratings published in the datasheets we hold. An en dash means the manufacturer does not publish that value; we do not fill it in with an estimate. Confirm every figure against the current manufacturer document before it is written into a contract.

Which one should you choose?
30 to 400 kW is a deliberate band
Below 30 kW the unit is oversized for the room and the price per kW works against you. Above 400 kW you are usually into a different product family and a different switchgear conversation. Inside the band the 93PM is chosen on footprint and efficiency rather than on features, because the feature set does not change across the capacities.
Transformerless matters for the room, not the datasheet
A transformerless design is lighter and physically smaller than an equivalent transformer-based UPS, which changes what the floor has to carry and how much of the room the unit occupies. On a retrofit into an existing building that is often the deciding factor, ahead of any efficiency figure. Ask for the weight and footprint at your capacity before the layout is fixed.
Sizing questions we will ask
The steady-state load in kW, the expected growth over three years, the runtime target and whether the site has a generator. Available capacities are 30, 50, 80, 100, 150, 200, 250, 300 and 400 kW, so the answer lands on a discrete step; knowing the real load stops you from paying for the step above it.
Parallel operation and future capacity
Units in this family can be paralleled, which gives two different things: more capacity, or the same capacity with redundancy. They are not the same purchase and they are not the same price. Decide which one you are buying before the single-line diagram is drawn, because retrofitting a parallel arrangement into a finished switchboard is expensive.
Harmonics and the upstream supply
A transformerless UPS presents a particular load to the incoming supply, and on a weak or generator-backed source the input current distortion matters. If the site runs on a generator for extended periods, confirm the generator sizing against the UPS input rather than against the load alone.
