Abstract

Aspects of the present disclosure provide systems and devices for providing power to one or more remote radio heads used in telecommunications. Some aspects provide a power supply system comprising a first power supply and a plurality of second power supplies configured to be installed in a rack shelf. Each of the plurality of second power supplies is configured to receive a first power signal from the first power supply and provide a second power signal to a respective remote radio head from a plurality of remote radio heads, and at least first inputs to each of the plurality of second power supplies may be ganged together.

First claim

What is claimed is:

1. A power supply system comprising:
a first power supply installed in a rack;
a plurality of second power supplies, each second power supply in the plurality of second power supplies configured to be installed in a rack shelf next to the first power supply installed in the rack, wherein a plurality of busbar extensions separately couple each of the plurality of second power supplies to the first power supply, wherein each busbar extension in the plurality of busbar extensions is an additional busbar to a busbar that couples components on the first power supply to one another, wherein each of the plurality of second power supplies is configured to receive a first power signal from the first power supply and provide a second power signal to a respective radio from a plurality of radios, wherein the radio is located outside the rack.

2. The power supply system of claim 1 , wherein the power supply system further comprising a module having a housing that comprises the plurality of second power supplies wherein the module is configured to be installed in a rack.

3. The power supply system of claim 2 , wherein the module further comprises a plurality of output breakers, with ones of the plurality of output breakers electrically coupled between each second power supply and the respective radio.

4. The power supply system of claim 3 , wherein the output breakers are each controlled by a respective toggle or switch located on a front panel of the rack shelf.

5. The power supply system of claim 3 , wherein the output breakers are controlled by a controller configured to receive input.

6. The power supply system of claim 1 , wherein the at least first inputs to each of the plurality of second power supplies are ganged together by a removable bar, and wherein removal of the removable bar results in each of the second power supplies being independently electrically coupled to the first power supply.

7. The power supply system of claim 1 , wherein each second power supply comprises a surge protection device or overvoltage protection device.

8. The power supply system of claim 7 , wherein each of the surge protection device or the overvoltage protection device is configured to protect a component within the respective second power supply from an overvoltage on an output from the second power supply.

9. The power supply system of claim 1 , wherein the first power signal is the same as the second power signal.

10. The power supply system of claim 1 , wherein the at least first inputs are provided on a front surface of a panel on the rack shelf.

11. The power supply system of claim 1 , wherein outputs from each second power supply are provided on a front surface of a panel on the rack shelf.

12. The power supply system of claim 1 , wherein each of the plurality of second power supplies is configured to adjust a voltage level of the second power signal such that the voltage at a radio end of a cabling connection between the second power supply and the respective radio is substantially constant notwithstanding variation in a current level of the second power signal.

13. The power supply system of claim 1 , further comprising an input breaker electrically coupled between the first power supply and the plurality of second power supplies.

14. The power supply system of claim 1 , wherein the first power supply is installed at a first location in a rack, wherein the rack shelf is installed at a second location in the rack below the first location, and wherein the plurality of second power supplies are electrically coupled to the first power supply via a busbar or busbar extension.

15. A telecommunications system comprising:
a plurality of remote radio heads outside a rack; and
a plurality of second power supplies, each second power supply in the plurality of second power supplies configured to be installed in a rack shelf in the rack, wherein each of the plurality of second power supplies is configured to receive a first power signal from the first power supply and provide a second power signal to a respective radio from the plurality of radios, and wherein at least first inputs to each of the plurality of second power supplies are ganged together;
a plurality of output breakers, wherein each output breaker is electrically coupled between a respective second power supply of the plurality of second power supplies and the respective radio, wherein the output breakers are each controlled by a respective toggle or switch, wherein the respective toggle or switch is located on a front panel of the rack shelf; and
a controller configured to control the respective toggle or switch for the output breakers in response to an input.

16. The telecommunications system of claim 15 , wherein the input provided to the controller is located at at least one of:
a location on a front panel of the rack shelf, and
remote from the location of the rack shelf.

17. A power supply system comprising:
a plurality of second power supplies, each second power supply in the plurality of second power supplies configured to be installed in a rack shelf next to a first power supply installed in the rack shelf, wherein a busbar extension separately couples the plurality of second power supplies to the first power supply, wherein the busbar extension is an additional busbar to a busbar that couples components on the first power supply to one another, wherein each of the plurality of second power supplies is configured to receive a first power signal from the first power supply and provide a second power signal to a respective radio from a plurality of radios; and
a plurality of output breakers, wherein each output breaker is electrically coupled between a respective second power supply of the plurality of second power supplies and the respective radio, wherein the output breakers are each controlled by a respective toggle or switch; and
a controller configured to control the respective toggle or switch for the output breakers in response to an input.

18. The power supply system of claim 17 , wherein the inputs to each of the plurality of second power supplies are provided on a front surface of a panel on the rack shelf.

19. The power supply system of claim 18 , wherein outputs from each second power supply are also provided on the front surface of the panel on the rack shelf.
