Description
The Eaton 9155 UPS Backup Power System is a high-performance double conversion online UPS designed to deliver continuous, clean power for mission-critical applications. With a 15 kVA power capacity, it protects servers, networking equipment, industrial automation systems, healthcare environments, banking infrastructure, and other sensitive electronics from power interruptions, voltage fluctuations, and electrical disturbances.
Engineered with true online double conversion technology, the Eaton 9155 continuously conditions incoming power to ensure maximum uptime and equipment protection. Its compact tower design minimizes floor space while accommodating 64 maintenance-free sealed lead-acid batteries for extended runtime capabilities. The system also supports an integrated customizable power distribution module with a maintenance bypass switch, simplifying servicing without interrupting connected loads.
Additional enterprise-grade features include automatic and maintenance bypass functionality, emergency power off (EPO), and dual X-Slot expansion bays for advanced network management and communications.
