The Energy Technologies ETI0001-S1R-KII/2.0 is a rugged, milspec uninterruptible power supply rated at 2000 VA, engineered for military, industrial, telecommunications, and computer systems operating in harsh environments. It delivers clean, galvanically isolated power with frequency conversion capability, transforming multiple input frequencies into stable 60 Hz output. Built for shipboard, airborne, vehicular, and fixed installations, the unit maintains power continuity even during AC loss and operates across wide input voltage and frequency ranges without enclosure access.
