3.8kVA-10kVA

208VAC

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.
