Eaton 93PM: key facts

Eaton lists the 93PM as current in two North American versions: the 93PM 208V, 10 to 200 kW at 208 V and 220 V, and the 93PM 480V, offered at 50 to 250 kW in a 250 kW frame with internal N+1 through 200 kW, which Eaton's overview says scales up to 500 kW. Eaton names the 93PM as a replacement option for the discontinued 93E and as comparable to the discontinued 9390. For service, Eaton's table keeps the 93PM 208 V in full support with no end date listed, and the first-generation 93PM (20 to 400 kW) in full support until best efforts begin in 2032.

Eaton 93PM three-phase UPS explained (10-250 kW)

2:23. The Eaton 93PM is Eaton's modular double-conversion three-phase UPS for data centres and other critical sites, rated 10 to 200 kilowatts at 208 and 220 volts, and 50 to 250 kilowatts at 480 volts in a 250 kW frame. This video covers what modular means here, which batteries it takes, what Eaton publishes about efficiency, and whether it is current.

0:00 What is the Eaton 93PM? What is the Eaton 93PM? It is Eaton's modular double-conversion three-phase UPS, built for data centres and other critical sites, rated 10 to 200 kilowatts at 208 and 220 volts, and 50 to 250 kilowatts at 480 volts in a 250 kilowatt frame.

0:20 What does modular mean here? What does modular mean here? Power comes in modules inside the frame, so capacity and serviceability are designed around the module rather than one monolithic box. You add capability by adding modules, and a module is the unit you service.

0:35 Which batteries does it take? Which batteries does it take? Eaton lists VRLA, AGM, gel, wet, or flooded, and lithium batteries. Cabinet options include an integrated battery cabinet, small or large, and a lithium battery cabinet. The chemistry and the cabinet size follow the load and the runtime target.

0:54 How efficient is it? How efficient is it? In plain double conversion it runs like any online UPS. With Eaton's optional Energy Saver System, the rectifier and inverter sit in a gated, ready state while the load is fed through the closed static bypass. Eaton publishes around or above 99 percent efficiency in that mode, and a return to full double conversion in about two milliseconds. That sits inside the twenty millisecond window IT loads ride through, so the efficiency gain does not cost the load its protection.

1:25 And long term? And long term? Eaton puts ESS losses near one percent, and its published reliability comparison gives roughly two to three times the mean time between failures of always-on double conversion, with far fewer fan hours. Those are Eaton's published numbers.

1:42 Is it current? Is it current? Yes. Eaton lists the 93PM as current, as a replacement option for the discontinued 93E, and comparable to the discontinued 9390.

1:55 Who is it for? Who is it for? Sites that need online double-conversion protection in the 10 to 250 kilowatt band: server rooms, edge data rooms, and mid-size data centres. If you are sizing one, request a quote at threephaseups.ca.

Maintenance visit checklist

What does a maintenance visit check on an Eaton 93PM?

2:21. On an Eaton 93PM the split is simple: the daily and monthly steps are yours, and everything inside the cabinet belongs to a scheduled visit by qualified service staff. This video walks the daily routine, the monthly parameter and air-filter checks, the battery options, the maintenance-bypass rule, and what the annual visit looks for, as printed in Eaton's 93PM installation and operation manual (P-164000711 Rev 12).

0:00 What does a maintenance visit check on an Eaton 93PM? What does a maintenance visit check on an Eaton 93PM? The split is simple: the daily and monthly steps are yours, and everything inside the cabinet belongs to a scheduled visit by qualified service staff.

0:13 What is on you daily? What is on you daily? Keep the area around the UPS uncluttered, keep the front air intakes and rear exhaust unblocked, keep the room within the specified environment, and confirm the normal indicator is lit. The manual also asks for surroundings clean and free from excess moisture.

0:30 What does the visit look for? What does the visit look for? The parts with a clock. Eaton's lifecycle schedule for its three-phase UPS puts fans at about year 7, the 93PM's capacitors at about year 10, and sealed batteries at 3 to 5 years, and says heat, load and dust move those numbers. The visit is where that wear gets measured.

0:50 What do you check monthly? What do you check monthly? Two things: review the system parameters on the control panel, and check the air filter behind the front door. Both are user steps, and the manual lists them under the monthly routine.

1:02 Which batteries does it take? Which batteries does it take? Eaton lists VRLA, AGM, gel, wet and lithium batteries. Cabinet options include Eaton's integrated battery cabinets, small and large, and a lithium battery cabinet. And battery work itself is qualified service staff only.

1:19 What about the bypass? What about the bypass? A transfer for maintenance can only happen when the bypass is healthy. While the load sits on the maintenance bypass, it runs on unconditioned utility power, with no conditioning and no battery backup.

1:32 What is on you, day to day? What is on you, day to day? Keep the area uncluttered, keep the air intakes and exhaust clear, keep the room within its specified environment, and confirm the normal indicator is lit. Everything inside the cabinet is qualified service staff work.

1:47 What does the visit cover? What does the visit cover? The fans at year 7, the capacitors at year 10, the batteries at 3 to 5 years, and the log history with the hardware. If an alarm lamp is lit or the normal indicator is out, the manual says to contact an Eaton service representative.

Energy Saver System & efficiency

The 93PM runs Eaton’s Energy Saver System (ESS), the eco-mode architecture documented across Eaton’s three-phase range. In ESS the rectifier and inverter are held in a gated, ready state while the load is fed through the closed static bypass, so the unit typically holds around or above 99% efficiency, even at light load, where conventional double-conversion efficiency falls away. Eaton puts ESS losses near 1% and the transfer back to full double conversion at roughly 2 ms, well inside the 20 ms ride-through IT loads tolerate. ESS also runs far fewer fan-hours and, on Eaton’s MIL-HDBK-217 comparison, 2 to 3× the MTBF of always-on double conversion. In Denmark, Eaton reports that over 90% of data centres using its three-phase UPS at 40 kW or above cut energy use by nearly 10% with ESS.

Sources: Eaton, Energy Saver System: Facts & Principles (WP15013EN) and E-guide to ESS (WP151002EN). We size and configure the system for your load; the figures are Eaton’s published specifications.
