Powerware series Eaton 9155/9355 UPS 8 - 40 kVA Scalable. Flexible. Compact.
Introduction and overview The Eaton® 9155/9355 uninterruptible power systems (UPS) are mid-size double-conversion UPSs that resolve all utility power problems and supply clean, continuous, uninterruptible power for the ever-expanding loads in today´s space-constrained server rooms. The 9155/9355 also offers an industry-leading combination of flexibility, scalability and power density – all in one high-efficiency package.
Premium power performance Double-conversion design for highest power protection Unlike some other commercially available UPS technologies, the double-conversion design used in the 9155/9355 completely isolates output power from input power anomalies and delivers 100-percent conditioned, perfect sine wave output, regulating both voltage and frequency. Even when presented with the most severe power disturbances, power output remains stable.
True reliability Powerware Hot Sync technology boosts power reliability Eaton’s Hot Sync technology is designed for parallel redundant N+1 systems to satisfy 24/7 applications. It can also be used in parallel capacity systems to enable customers with ever-increasing load demands to take advantages of the scalability benefits it offers. Thanks to Hot Sync, up to four equivalent 9155/9355 modules can be paralleled for additional capacity or redundancy.
Extensive configurability Enhanced communication capabilities The 9155/9355 UPS is equipped with a variety of standard communications features for network connectivity and remote management applications, including: • RS-232 serial port • Two X-Slot® communication bays • Relay output contacts • Two programmable signal inputs • Remote emergency power-off (REPO) ConnectUPS-X Web/SNMP X-Slot card Easy network connectivity and monitoring ConnectUPS-X Web/SNMP card The ConnectUPS-X Web/SNMP X-Slot card connects
