The Xtreme Power Conversion P91-3000 and APC Smart-UPS SRT3000XLA are true online, double-conversion UPS systems designed to protect mission-critical IT, network, and edge infrastructure. Both deliver continuous sine-wave output and enterprise-grade protection from power disturbances.
However, the P91-3000 differentiates itself with higher usable output power, a shallower rack footprint, longer battery design life, stronger battery warranty coverage, and full TAA compliance, making it especially well suited for space-constrained deployments and federally regulated procurement environments.
