Dramatically reduce onboard battery power consumption with a Smart Energy Controller. The ISEC is designed for easy mounting to the Danfoss DC module on Cruise Elegance Refrigerators and with most appliances and systems that use Danfoss compressors with DC electronics modules. With sophisticated, processor-based Smart Energy Control technology, they achieve significant power savings by continuously scanning key environmental factors to optimize compressor speed and maximize the performance/battery drain ratio. The result is up to 35% savings due to a more efficient use of the compressor and up to 50% savings with combined effects of stored cooling energy in food and drinks. Measures 4-1/2"H x 2"W x 1-1/2"D. Two-year warranty. Recommended use: Cabinet refrigerators with Danfoss DC electronic modules
