Abstract
A system includes one or more constant “on” outlets, one or more controlled outlets, a two-part power supply, and accompanying circuitry. Other embodiments are also disclosed herein.
Claims23
A relocatable power tap, comprising:
- a power supply circuit configured to receive an input AC power signal and produce an 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 output AC power signal, the first DC power signal and the second DC power signal, the control circuit including;
- a driver circuit, the driver circuit configured to receive the second DC power signal as a power source, the driver circuit further configured to receive a command signal and produce a control signal based on the received 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 output AC power signal, the controlled switching circuit further configured to receive the control signal from the driver circuit and provide the output AC power signal to a controlled outlet based on the received control signal;
- an input circuit, the input circuit coupled to the control circuit and configured to provide a command signal to the driver circuit of the control circuit, the command signal indicating whether a controlled outlet is to receive power;
- and
- at least one controlled power outlet, the at least one controlled power outlet having an input electrically coupled to the controlled switching circuit and an output configured to electrically coupled to an external device, the at least one controlled power outlet configured to receive the output AC power signal from the controlled switching circuit and provide the received output AC power signal to an external device.
5 more elements
A power supply for a relocatable power tap, comprising:
- a first power supply module configured to receive an input AC power signal;
- and
- a second power supply module;
- wherein the first power supply module and the second power supply module when coupled can be operative to provide an output AC power signal to an external load, a first DC power signal to a first internal load and a second DC power signal to a second internal load.
1 more element
A method for providing a selectable output AC power signal, comprising:
- producing an output AC power signal, a first DC power signal and a second DC power signal at a power supply and based on a received input AC power signal;
- producing a control signal at a control circuit based on a received command signal and the second DC power signal;
- powering a switch circuit with the first DC power signal based on the control signal and the second DC power signal;
- and
- providing the output AC power signal to a load when the switch circuit is powered.
2 more elements
An apparatus, comprising:
- a power supply comprising:
- a first power supply module configured to receive a first input power signal and configured to provide a first DC output power signal at a first power level;
- a second power supply module electrically coupled to the first power supply and configured to provide a second DC output power signal at a second power level lower than the first power level;
- a first circuit receiving the first DC output power signal;
- and
- a second circuit receiving the second DC output power signal.
