The Xtreme Power Conversion TX91-5kVA and the NXT Power Integrity Max NPTU5200-0 are true online, double-conversion UPS systems with integrated isolation transformers, designed for electrically noisy, mission-critical industrial, laboratory, and infrastructure environments. Both deliver galvanic isolation, strong surge suppression, and multi-voltage output flexibility.
However, the TX91-5kVA differentiates itself with longer internal runtime options, an XR extended-runtime variant, plug-and-play configuration flexibility, and built-in TAA compliance, making it particularly well suited for regulated and federal procurement environments.

Where the TX91-5kVA Excels
- Federally funded and TAA-restricted procurement environments
- Industrial and laboratory installations requiring galvanic isolation
- Applications benefiting from longer internal runtime without external batteries
- Deployments requiring XR extended-runtime flexibility
- Space-constrained installations favoring a narrower, shallower footprint
When NXT Integrity Max NPTU5200-0 May Be a Fit
- Facilities requiring OSHPD/HCAi-listed equipment
- Existing NXT Integrity Max standardized deployments
- Projects where TAA compliance is not required
- Traditional industrial power-quality applications
Who Should Choose Which
Choose Xtreme Power Conversion TX91-5kVA if you need:
