The Eaton ® 93PS uninterruptible power supply (UPS) is a true online,
continuous-duty, transformerless, double-conversion, solid-state, three-phase
system that supplies conditioned and uninterruptible AC power to critical load
and protects it from power failures.
The UPS 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 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 require for
reliable operation. During brownouts, blackouts, and other power interruptions,
batteries provide emergency power to safeguard operation.
The UPS system is housed in a single, free-standing cabinet with safety shields
behind the door for protection against hazardous voltage. Each UPS cabinet has
a centralized system static bypass. The available static bypass ratings are 20
kW and 40 kW. The static bypass size is chosen according to UPS system
power. For example, if a future requirement is to upgrade the UPS capacity, the
UPS bypass rating has to be selected accordingly. In addition, the bypass
ratings of all the UPS cabinets in a parallel system need to be matched.
Eaton 93PS output power ratings are based on 15 kW and 20 kW rated
uninterruptible power modules (UPMs). With the small 20 kW frame, a single
UPS cabinet can house one UPM module to get ratings of 8 kW, 10 kW, 15 kW
or 20 kW. With the large 40 kW UPS frame, a single UPS cabinet can house
one or two UPM modules to get ratings of 8 kW, 10 kW, 15 kW, 20 kW, 30 kW
