The Xtreme Power Conversion TX91-10kVA and the NXT Power Integrity Max NPTU10.0 are true online, double-conversion UPS systems with integrated isolation transformers, designed for electrically noisy, mission-critical industrial, laboratory, and infrastructure environments. Both provide galvanic isolation and strong surge immunity.
However, the TX91-10kVA differentiates itself with full 10kVA / 10kW (unity power factor) output, longer internal runtime, extended-runtime (XR) capability, a narrower and shallower footprint, and built-in TAA compliance, making it better suited for regulated and federal deployments.

Where the TX91-10kVA Excels

  • Federally funded and TAA-restricted procurement environments
  • Industrial and laboratory applications requiring galvanic isolation
  • Installations needing full 10kW usable output from a 10kVA UPS
  • Sites prioritizing longer internal runtime without external batteries
  • Deployments where smaller footprint and rack optimization matter

When NXT Integrity Max NPTU10.0 May Be a Fit

  • Existing NXT-standardized power quality environments
  • Installations aligned to OSHPD/HCAi-listed infrastructure requirements
  • Projects where TAA compliance is not required
  • Facilities preferring a traditional hardwired isolation UPS architecture

Who Should Choose Which

Choose Xtreme Power Conversion TX91-10kVA if you need:

  • Full 10kVA / 10kW (unity PF) output
  • Built-in TAA compliance for federal, education, and public-sector projects
  • Longer internal runtime and XR extended-runtime capability
  • A narrower, shallower isolation UPS for space-constrained installations
  • Simplified procurement for regulated environments

Choose NXT Integrity Max NPTU10.0 if you need:

  • Alignment with an existing NXT Integrity Max deployment standard
  • Compliance with OSHPD/HCAi-specific facility requirements
  • Deployment in non-TAA-regulated projects

Ideal Applications

  • Industrial control systems
  • Laboratory and test environments
  • Manufacturing and process automation
  • Federal, education, and public-sector facilities
  • Sensitive loads requiring galvanic isolation
