TX91 3.8-10kVA Isolated Online Tower UPS

The Xtreme Power TX91 UPS delivers true isolated online protection with a galvanic isolation transformer, providing the cleanest, most reliable power for demanding and noise-sensitive environments.

Unlike transformerless online designs, the TX91 prevents common-mode noise, eliminates ground interference, and provides power conditioning even in bypass mode — ensuring total protection for your most critical systems.

Available in 3.8 kVA, 5 kVA, 6 kVA, and 10 kVA models, the TX91 features unity power factor (1.0) and configurable dual output voltages of 240/120 VAC or 230/115 VAC, making it ideal for global and mixed-load installations.

Key Features & Benefits

• Galvanic Isolation Transformer – Eliminates common-mode noise and the need for costly dedicated circuits, while providing continuous power conditioning during normal and bypass operation.
• Dual Output Voltages – Configurable 240/120 VAC or 230/115 VAC output supports a wide range of equipment and receptacle types.
• True Online Double-Conversion Design – Protects against all 10 common power problems with seamless inverter-to-bypass transfer.
• Integrated Static Switch – Ensures instantaneous transfer to the isolated bypass in case of overload or internal fault.
• Extended Runtime Options – Internal 580 W batteries (XR models) or external battery cabinets extend runtime to meet site requirements.
• Superior Surge Protection – < 10 V (L–N) and < 0.5 V (N–G) let-through when tested to ANSI/IEEE C62.41 Cat A 6 kV standards.
• Auto Restart Function – Automatically resumes operation when utility power returns after full discharge.
• Advanced LCD Display – Monitors input/output voltages, load levels, alarms, and battery status in real time.
• UL1778, cUL, FCC Class A, RoHS, and TAA Compliant – Certified for commercial, industrial, and government use.
• 3-Year Warranty – Electronics and batteries covered in the U.S. and Canada.
