摘要

energized device intended for use in an electrical distribution system, electrical distribution system, method for providing electrical charge power to an electrical charge from an energized device, and computer program for providing electrical charge power to a The electrical charge of an energized device The invention relates to an energized device (2), such as a luminaire, intended for use in an electrical power distribution system (100) which is preferably a power system and comprising a device. power supply (1). The energized device includes an electrical charge such as a light source, a voltage measurement unit to measure a voltage received by the energized device, and an electrical charge power supply unit to transform the energy supplied by the power supply device. in an electric load power to be supplied to the electric load, where the power level of the electric load power depends on the measured voltage. This allows the input power to be adapted to the actual received voltage which can be reduced due to losses such as cable losses which in turn can lead to an increase in the input energy of energized devices according to the current ieee standard. 802.3at for poe. 1/1
