TX90 Isolated Online UPS


230VAC or 120VAC

Online UPS with isolation transformer for complete power protection.

Equipment that is impacted by poor power can result in downtime, inaccurate test results, and increased service costs. TX90 provides reliable galvanically isolated power to critical equipment. Output voltages can be selected from the TX90 LCD display 100V to 120V or TX90i from 200V to 240V. TX90 worldwide input feature allows connection to just about any power source – voltages from 88V to 288V (up to 3kVA) and frequencies from 40Hz to 70Hz.
