TX91 3.8-10kVA Isolated Online Tower UPS

3.8kW – 10kW | 240/120VAC or 230/115VAC | Isolated Online Tower UPS

The Xtreme Power TX91 Series delivers 3.8kW to 10kW of true online double-conversion power in a compact tower configuration designed for laboratory, analytical, and precision electronic environments.

Engineered with an optional integrated isolation transformer, the TX91 eliminates common mode noise and provides galvanic isolation between utility input and critical loads. This makes it ideal for mass spectrometers, research instrumentation, pharmaceutical labs, and other sensitive applications where power quality directly impacts performance.

Why Isolation Matters in Laboratory Environments

Analytical instruments are highly sensitive to:

• Common mode noise
• Voltage fluctuations
• Harmonic distortion
• Ground potential differences

The TX91 isolation transformer option electrically separates the load from upstream disturbances, improving measurement stability and protecting sensitive electronics.

In many laboratory and research facilities, an isolation transformer UPS is not optional — it is a best practice for ensuring data integrity and repeatable results.

Comparing the TX91 to Other Isolation UPS Platforms

Evaluating alternatives or standardizing across laboratory sites often requires a side-by-side comparison.

See how the Xtreme Power TX91 compares to NXT and Powervar isolation UPS platforms by voltage class, topology, isolation design, runtime capability, and lifecycle cost.
