The Superior Electric rack-mount SEG UPS series is a high efficiency uninterrupted power supply (UPS). A 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 sine wave and tightly regulated source to connected equipment.
