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.
