Introduction

Figure
Eaton's 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 Eaton 9390 UPS is available as a single module or a multiple
module parallel system (see paragraph 1.3).
The 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 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 Eaton 9390 UPS (100–160 kVA).
