Eaton FERRUPS 3.1kVA Tower UPS 120 V AC | Ferro-resonant, Enterprise

Maintain clean, regulated power for systems that cannot tolerate interruption. The Eaton FERRUPS 3.1kVA Tower UPS is built around ferro-resonant technology, delivering stable 120 V AC output while filtering harmful harmonic currents that can affect sensitive electronics and building wiring. With 3,100 VA and 2,200 W capacity, it supports demanding infrastructure with the headroom needed for controlled shutdowns and short-duration ride-through. This tower UPS is designed for critical operations where power quality matters as much as backup time. Its 14-minute full-load runtime gives teams a practical window to bridge outages, complete failover actions, or bring systems down safely. The zero transfer time helps avoid disruption during source changes, while active voltage regulation keeps output consistent without drawing from batteries unnecessarily. Three NEMA L5-30R receptacles provide direct connectivity for compatible equipment, and the included power management software supports monitoring and orderly response. For facilities that run essential communications, control systems, or specialized IT loads, FERRUPS delivers the kind of electrical conditioning and runtime discipline that lower-tier UPS units cannot match.
