93PM-L 60 kW, Four-Wire uninterruptible power supply (UPS) is a true online, continuous-duty,
transformerless, double-conversion, solid-state, three-phase system, providing conditioned and uninterruptible
AC power to protect the customer's load from power failures.
The Eaton 93PM-L UPS online power protection system is used to prevent loss of valuable electronic
information, minimize equipment downtime, and minimize the adverse effect on production equipment due to
unexpected power problems.
The Eaton 93PM-L UPS continually monitors incoming electrical power and removes the surges, spikes, sags,
and other irregularities that are inherent in commercial utility power. Working with a building's electrical
system, the UPS system supplies clean, consistent power that sensitive electronic equipment requires for
reliable operation. During brownouts, blackouts, and other power interruptions, batteries provide emergency
power to safeguard operation.
The Eaton 93PM-L UPS is available with up to three Uninterruptible Power Modules (UPMs) integrated in one
cabinet. Each UPM is rated for a maximum of 20 kW. The system maximum rating is 60 kW. To deliver greater
reliability, a UPS with two or more UPMs can provide N+1 redundancy up to a maximum of 40 kW. Should one
UPM become unavailable or require servicing, the remaining UPMs supply the load instead of transferring to
bypass.
The UPS is housed in a single free-standing cabinet, with safety shields behind the door for hazardous voltage
protection. Power wiring is installed through the bottom of the cabinet with an optional sidecar available for top
entry wiring.
