Powerware 9390 UPS
Powerware 9390 UPS series

The Powerware 9390 UPS power solution provides the best combination of power performance, battery management, scalable architecture, flexibility, power density, and warranty and service.

The Powerware 9390 UPS power system is designed to meet the current and future power protection requirements of data centers, manufacturing operations, medical facilities and other large-system applications.

Powerware 9390 UPS Features and Benefits:

  • Unmatched Power Performance:

    • High efficiency of 94 percent reduces total cost of ownership by reducing cost of power to support protected loads

    • Low total input harmonic current distortion (THD) of less than 4.5 percent enhances compatibility with upstream power systems, especially generators

    • Input power factor of 0.99 minimizes auxiliary generator sizing requirements and provides more power to unity power factor servers

    • Output power rated at 0.9 power factor accommodates high power factor load requirements

    • Double-conversion design offers the highest protection possible

  • Enhanced Scalability:

    • Utilizes Powerware Hot Sync technology to parallel for capacity and redundancy

    • Up to four (4) UPS modules can be paralleled with a tie cabinet, while a total of eight (8) modules can be paralleled (providing a total capacity of 1280 kVA) at a maximum

  • Best Total Battery Management:

    • Extends battery life and optimizes battery recharge time via patented ABM technology

    • Integrated battery management system tests and monitors battery health

    • Optional temperature-compensated charging monitors battery temperature and extends battery life

    • Variable battery buss matches battery capacity to exact customer runtime

    • Enables remote monitoring of the UPS and battery system

  • Flexible Installation and Serviceability:

    • Reduces installation time and costs with small footprint and flexibility to install against walls, using top- or bottom-entry cabling

    • Front-panel access for all services and operation increases serviceability and reduces repair time

  • Superior Warranty and Service:

    • Features a one-year limited factory warranty (parts and labor)

    • Service protection package includes Start-Up service, a UPS Performance Check, one year of battery replacement labor coverage*, and one year of web remote monitoring of both the UPS and batteries
