CIRCUIT DEVICE DISPLAYING CURRENT CONSUMPTION OR POWER CONSUMPTION OF ELECTRIC LOAD

摘要

A circuit layout for continuous display of power consumption of an electric device includes a light emitting diode actuated by voltage pulses, the frequency whereof corresponds to the current draw of the electric device. It is possible to determine directly whether the instantaneous power consumption of the electric device, in particular a household device, is low or high in case of varying loads as the frequency of the voltage pulses and thus the flashing frequency are below the flicker limit resolvable by the human eye. The power consumption display can be manufactured in a highly cost effective manner and in a compact configuration, so that it may be placed in an electric outlet housing.
