Introduction

Figure
Eaton's Powerware 9390 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 all nine power failures. The Powerware 9390 UPS is available as a single module
or a multiple module parallel system (see paragraph 1.3).
The Powerware 9390 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 Powerware 9390 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 UPS system is housed in a single, free‐standing cabinet with safety shields
behind the door for hazardous voltage protection. The cabinet matches the battery
and distribution cabinets in style and color and can be installed in line-up-and-match or
standalone configurations. Figure 1‐1 shows the Powerware 9390 UPS (20–80 kVA).
