Introduction

The 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 1.1).

The Powerware 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 es 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 (100–160 kVA).
