Introduction

The Powerware 9155 is a double-conversion, split-phase, online uninterruptible
®
power system (UPS) for protecting computer systems and other intelligent devices. It
is ideal for protecting essential information technology and electrical engineering
infrastructure in corporate, telecom, health care, banking, and industrial applications.
The UPS provides a steady, well-regulated power supply for your computing and
communications equipment, while protecting it from the frequent irregularities that
are inherent in commercially available power. Voltage spikes, power surges,
brownouts, and power failures have the potential to corrupt critical data, destroy
unsaved work sessions, and in some instances, damage expensive hardware.
With the Powerware 9155, you can safely eliminate the effects of electrical line
disturbances and guard the integrity of your systems and equipment. Figure 1 shows
the Powerware 9155 UPS and an optional Extended Battery Module (EBM).
