The Xtreme Power Conversion T91-1000 and the Eaton 9SX1000 are true online, double-conversion UPS systems designed to protect compact, mission-critical IT, networking, and AV loads. Both provide continuous sine-wave output and full isolation from power disturbances.
However, the T91-1000 differentiates itself with higher usable watt capacity, significantly greater runtime scalability, configurable high-capacity charging, a more compact physical footprint, and built-in TAA compliance, making it better suited for regulated and space-constrained deployments.
