P91g – Scalable Runtime Online Power Protection for Global IT & Commercial Infrastructure

1500–3000 VA Online Double-Conversion UPS | External Battery Expansion Platform (208 / 230 V)

The Xtreme Power Conversion P91g Series is a compact online double-conversion UPS platform engineered to deliver continuous conditioned 208 / 230 V power with scalable runtime for international IT infrastructure, AV systems, hospitality environments, education facilities, retail technology deployments, and commercial installations.

Online double-conversion UPS architectures are deployed where zero transfer time, precise voltage regulation, and reliable protection of sensitive electronic loads are required. The P91g platform extends this capability through external battery expansion, enabling runtime scalability from short-duration ride-through to extended outage mitigation.

With unity power factor output, flexible rack / tower deployment capability, and TAA-compliant manufacturing, the P91g supports infrastructure standardization initiatives across global and regulated environments requiring dependable power continuity.

Why Scalable Runtime Online UPS Architecture Exists

Compact UPS systems with fixed internal batteries often provide limited runtime during extended power disruptions. External battery expansion architectures address:

• extended runtime requirements for critical infrastructure
• distributed IT continuity strategy
• outage risk mitigation planning
• runtime standardization across multi-site deployments
• resilience planning for AV and commercial technology systems

Capacity & Runtime Strategy

The P91g platform is engineered for distributed infrastructure environments where runtime requirements extend beyond the capabilities of fixed-battery compact UPS systems. External battery expansion enables infrastructure planners to design runtime profiles aligned with operational continuity objectives, outage risk tolerance, and site-specific protection strategies.

Typical deployment scenarios include:

• AV system uptime assurance and controlled shutdown planning
• network infrastructure continuity during facility power interruptions
• education technology protection and classroom operational resilience
• distributed enterprise IT and edge computing environments
• retail and hospitality continuity strategy

Available configurations:

• 1500 VA / 1500 W
• 2000 VA / 2000 W
• 3000 VA / 3000 W

Output voltage:

• 208 / 230 VAC nominal

Runtime scalability enables:

• short-duration ride-through for power quality events
• medium-duration runtime for controlled system shutdown
• extended runtime with external battery packs for critical continuity

External battery architecture supports:

• runtime standardization across global deployments
• infrastructure resilience strategy development
• phased modernization of legacy UPS installations
• outage risk mitigation planning
