Overview

An industry first — Mid-Continent Instruments & Avionics brings you the first emergency power supply featuring Lithium Nanophosphate™ technology. The MD800 Series weighs merely 4.7 pounds – 8 pounds less than the competition. It charges faster, costs less and has an improved ten-year life expectancy. Did we mention it uses the same mating connector and install rack as existing power supplies? Never underestimate the power of innovation. The MD835-5 adds an integrated adjustable 5-volt output for special lighting requirements.
