Xtreme Power TX91 Isolated Online Tower UPS Series

Xtreme Power TX91 Isolated Online Tower UPS Series

– 3.5kVA – 5.OkVA – 6.0kVA – 10.0kVa Isolated online UPS

SKU: TX91 Isolated Online UPS Series

Product Information

Isolated online UPS provides protection from all 10 common power problems

Isolated online UPS provides the cleanest power in the most demanding conditions. The TX91 galvanic isolation transformer prevents common mode noise which is left exposed by typical transformerless online designs.

Isolated online applications include retail, industrial environments, laboratories, and any installation with grounding or noise issues.

TX91 provides dual output voltages and optional configurable PDU to meet a wide range of receptacle requirements.
