EVS-EN IEC 62386-221:2018

The IEC 62386 series specifies a bus system for control by digital signals of electronic lighting equipment. This electronic lighting equipment should be in line with the requirements of IEC 61347, with the addition of d.c. supplies.
The methodology of load shedding focuses on curtailment of loads during peak demand times thus avoiding the requirement to find new sources of generation capacity. By this the lighting system responds to the demands of the energy supply. This part of IEC 62386 is applicable to control gear supporting load shed functionality.
