Abstract
An electrical power strip has a base, a power cord and a control module. The base has at least one primary receptacle and at least one secondary receptacle. The control module is connected to the power cord and has two power input terminals, at least one primary contact set, a voltage regulating circuit, a current indicating circuit, a comparator, a driving circuit and at least one secondary contact set. The two power input terminals are connected to the power cord. The voltage regulating circuit is connected to the two power input terminals and outputs a regulated voltage. The current indicating circuit is connected to the primary contact set and the voltage regulating circuit to output direct current. The comparator checks for the regulated voltage and the direct current and then outputs a control signal. The control signal applies power to the secondary contact set.
