Abstract: The supply of power to cyclical, separately controllable loads is controlled without interrupting the operating cycle of the loads. A controllable power supply switch interrupts the power supply circuit to the load only when signalled by a load cycle switch. A power demand monitor and limiter senses the total power being consumed by all of the loads, and generates signals indicating that the supply of power to one or more of the loads is to be interrupted when the total power consumed approaches a given maximum. A load cycle switch generates a signal when an operating cycle of a load is completed. A load gate allows the power demand monitor and limiter to pass a control signal to the power supply switch to cause it to interrupt the power supply circuit to the selected load, only after the load gate has received a signal from the load cycle switch indicating the completion of an operating cycle.
