ABSTRACT:
An electrical load controller circuit for controlling power consumption is described. A detection circuit detects the current flowing through a supply line and produces an output signal representative thereof. A comparator circuit compares the output signal with an adjustable reference signal which is indicative of the maximum power to be consumed by loads connected to the supply line. All of the loads are connected to switching circuits, and these are enabled and disabled by signals received from a decade counter which is in turn controlled by inverters and timer circuits whereby loads can be placed in service in a sequential manner. A modulator intermittently controls the time periods that the electrical load is connected to the supply line as well as the ON and OFF periods of the loads for daytime or nighttime operation.
