Chapter 1 Introduction
The Eaton
®
9355 uninterruptible power supply (UPS) is a true online, double-conversion, three-phase system
that can be used to prevent loss of valuable electronic information and minimize equipment downtime. It is
ideal for protecting essential information technology and electrical engineering infrastructure in corporate,
telecom, health care, banking, and industrial applications.
The Eaton 9355
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 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.
With the Eaton 9355 UPS, you can safely eliminate the effects of electrical line disturbances and guard the
integrity of your systems and equipment. Figure 1 shows the Eaton 9355 UPS (20/30 kVA) with an optional
Extended Battery Cabinet (EBC) and Options Cabinet.
