SEG Series True On-Line Uninterruptible Power Supplies

True Regenerative On-Line technology provides the highest level of protection against a broader spectrum of power problems. This is accomplished through converting the incoming AC utility voltage to a regulated DC voltage. From this DC voltage, a new AC voltage is regenerated by the UPS, providing a clean sinewave and tightly regulated source to connected equipment. UPS is offered in 120 and 230 VAC, Cabinet and 19-Inch Rack Mount, from 1kVA to 6kVA ratings.
