Circuit arrangement and method for mains voltage-dependent power control of an electronic device, in particular an electronic ballast

摘要

The invention relates to a circuit arrangement for mains voltage-dependent power control of an electronic device (3), which means (DC) with which a DC operation or AC operation of the electronic device (3) is detectable and which has a control unit (32) in which at least one Power-line voltage characteristic (321) for a DC operation and at least one power-line voltage characteristic (322) for an AC operation of the electronic device (3) are stored, wherein the control unit (32) is designed such that depending on the detected operation of the electronic device (3) a regulation of the recording of the electrical power of the electronic device (3) depending on the associated power-line voltage characteristic (321, 322) is feasible. The invention also relates to a method for mains voltage-dependent power control of an electronic device. The electronic device is advantageously designed as an electronic ballast (3).
