Patent ID: 8232683

Claim:
A relocatable power tap configured to removably couple to an external device, the relocatable power tap comprising: at least one controlled power outlet; a power supply circuit configured to receive an input AC power signal and produce a first output AC power signal, the power supply circuit having a first stage and a second stage, the first stage of the power supply circuit configured to produce a first DC power signal and the second stage of the power supply circuit configured to produce a second DC power signal; a control circuit in electrical communication with the power supply circuit and configured to receive the first output AC power signal, the first DC power signal, and a command signal, the control circuit including: a driver circuit, the driver circuit configured to receive the command signal and produce a control signal based on the command signal; and a controlled switching circuit in electrical communication with the driver circuit and configured to receive the first DC power signal as a power source and to receive the first output AC power signal, the controlled switching circuit further configured to receive the control signal from the driver circuit and provide a second output AC power signal to the at least one controlled power outlet based on the control signal; and an input circuit, the input circuit coupled to the power supply circuit and to the control circuit and configured to receive the second DC power signal and to provide the command signal to the driver circuit of the control circuit, the command signal indicating whether the at least one controlled power outlet is to receive the second output AC power signal, wherein: the at least one controlled power outlet having an input electrically coupled to the controlled switching circuit and an output configured to electrically couple to the external device, the at least one controlled power outlet configured to receive the second output AC power signal from the controlled switching circuit and provide the second output AC power signal to the external device.
