The Danfoss ERC 102 is an energy-efficient electronic refrigeration controller. Operating between 50 and 300V at 50-60 Hz, the 0.5W controller uses four inputs and outputs each. The controller can reduce the refrigerator’s energy consumption by up to 52% when fitted onto a standard one-door glass door merchandiser with a mechanical thermostat, a fan, and a 0.5HP compressor. You can also individualize settings for lighting schedules, fan control, and compressor operating times.
