ABSTRACT:
According to the supply system, a customer purchases a chip corresponding to a predetermined amount of electricity from a power company and sets the chip in a control device installed in the customer house. The supply system comprises an integrating watthour meter which integrates the power consumed by the customer and generates a pulse signal for each unit of consumed power, a timer responsive to the output of the integrating watthour meter for producing a time signal corresponding to a predetermined rate calculating interval, a multi-rate calculating unit responsive to the timer signal and the pulse signal for independently calculating a plurality of operation rate elements an electric switch for supplying power to the customer, a rate detection selection unit including a rate detection member, a multi-rate calculation function unit including a plurality of elements which are set with various parameters regarding tax and rate and adapted to be combined with the multi-rate calculating unit for calculating the rate, and a rate function unit including a rate element set with an amount of power corresponding to the amount of purchased power and adapted to be combined with the rate selection detection unit for producing a rate signal corresponding to the purchased amount of power. The switch is controlled by the rate signal for supplying to the customer a predetermined amount of power.
