Product description

Eaton 93PM UPS 20-400kVA

The Eaton 93PM 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 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 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 UPS is available with up to (10) Uninterruptible Power Modules (UPMs) integrated in one cabinet. Each UPM is rated for a maximum of 50 kW. The system maximum rating is 200 kW per UPS frame. To deliver greater reliability, UPS with two or more UPMs can provide N+1 redundancy  Should one UPM become unavailable or require servicing, the remaining UPM supplies 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.


The Eaton® 93PM UPS combines high efficiency and reliabilitywith an eye-catching design. A space-saving, scalable and flexible device that’s as easy to deploy as it is to manage; it’s the perfect three-phase white or grey space solution for today’s data center.

Double Conversion Online UPS

Double Conversion Technology

Double Conversion Topology

The Eaton 93PM uninterruptible power supply uses the Double Conversion Online UPS topology.  This  provides the ultimate in clean and stable electrical power for critical applications.  Incoming AC power is fed to the UPS’ rectifier converting it from AC to DC power. The converted DC power routes to a battery charging circuit and to the inverter for conversion back to AC power. The resulting “double converted” electrical power is pure sine wave output providing near perfect electrical power for connected equipment.

To ensure 7/24 up time the double conversion UPS topology utilizes a static “bypass switch” within its circuity design. If the Eaton 93PM detects a system failure, audible alarms will sound as the bypass switch is engages. This routes power around the failed UPS and ensures critical load power to target equipment.  This very important feature allows for 100% up time for critical equipment during repair.

In the event of total power failure, the UPS will power off the rectifier when the loss of power is detected. The UPS’ internal backup batteries will continue to supply DC power to the inverter. There is no transfer time as the transition to battery power is instantaneous. This feature provides true uninterruptible power to mission critical equipment.
