Definitions

  • the present invention relates to a system and method for distributing electrical power, of particular but by no means exclusive application in either existing or new cabling infrastructures in residential or commercial environments .
  • POE power over Ethernet
  • a standard fixed-line telephone uses essentially this approach. Some amplifiers have also been powered in this way. In all these cases, however, the power is injected remotely solely for powering the remote device at the other end of that cable and that is sending its data signals back through that cable.
  • Any other equipment in such systems must still be located where mains power can be made available; this is not always so or, if it is, may entail inconvenience or excessive cost.
  • many cabling installers are not fully licensed electricians and are therefore unable - when install new equipment or cabling - to move mains power points or install new points to provide power for that equipment .
  • the present invention provides, therefore, a system for distributing electrical power, comprising: a power injector electrically couplable to a data cable for putting a voltage across the cable; a power extractor electrically couplable to the data cable; and an output (such as an output terminal) electrically coupled to the power extractor and electrically couplable to an electrical device; wherein some or all electrical power injected into the data cable with the power injector can be accessed at the output.
  • the voltage extractor and output may be provided as an integral unit, or in an amplifier, or both.
  • any device can be powered by injecting voltage and then extracting that voltage at the location of the device from an amplifier module (such as where mains power is not easily accessible) .
  • the invention is thus envisaged to be of particular value in locations that are suitable for the installation of such electrical devices that require electrical power but unsuitable or inconvenient for the provision of mains power (or where the devices cannot be powered efficiently or adequately by battery) .
  • Devices can be powered whether connected to the cabling or not.
  • a cabling system can thus be installed fully without consideration of the provision or location of mains power.
  • the extractor may be located inside a cabling cabinet, thereby allowing remote powering of devices within the cabinet.
  • This embodiment has several advantages. Firstly, such cabinets are often limited in available space and this embodiment frees up space that would otherwise be used by power transformers. Secondly, commonly there are regulations imposed by Certification authorities as to the proximity of mains cable to low voltage (e.g. data and telephone) equipment or cables; this embodiment extracts low voltage in the cabinet, thereby conforming to such regulations . Thirdly, the performance of high speed data transfer/ RF signals can be affected by close proximity to electrical transformers; the extracted low voltage in the cabinet does not produce such interference.
  • the power can be extracted to power other unrelated devices located at a remote position from the point of injection
  • the extractor can be either part of the device, as a part of the cabling system or it can be a separate unit.
  • the invention uses the power for either additional system equipment not directly related to the cable signal, or where there is no system equipment involved, the extracted voltage can be used to power devices unrelated to the signal in the cable.
  • the invention also provides a power extractor as described above.
  • the invention provides a power injector as described above.
  • the invention provides a method of distributing electrical power as described above.
  • Figure 1 is a schematic view of a power distribution system according to a first embodiment of the present invention
  • Figure 2 is a schematic view of a power distribution system according to a second embodiment of the present invention.
  • Figure 3 is a schematic view of a power distribution system according to a third embodiment of the present invention.
  • FIG. 1 is a schematic view of a power distribution system 10 according to a first embodiment of the present invention.
  • a coaxial cable is run to a structured cabling cabinet (SCC) that contains an extractor located in an Amplified Splitter Extractor Module (ASEM) .
  • SCC structured cabling cabinet
  • ASEM Amplified Splitter Extractor Module
  • the system includes a low voltage 2 Amp transformer 12 (plugged into a mains socket 14) .
  • the 2 Amp power rating on the transformer 12 is required to power devices (such as the Amplified Splitter Extractor Module (ASEM) described below) , and converts the mains 240/110V AC to low voltage (in this embodiment, 12 V DC) .
  • the low voltage output is then connected to a Power Injector Unit (PIU) 16.
  • the PIU 16 has two connectors
  • a first connector for coupling the PIU 16 to a coaxial cable wall socket 18 and a second connector for coupling the PIU 16 to an optional device which, in this embodiment, is in the form of a television 20.
  • the PIU 16 applies the low voltage from the output of the transformer 12 to the conductors of the first connector.
  • the PIU 16 blocks the coupling of the low voltage to its second connector so that television 20 is protected from this low voltage.
  • the PIU 16 is connected from its first connector to the coaxial cable wall socket 18.
  • An installed coaxial cable 22 couples the coaxial cable wall socket 18 to a Structured Cabling Cabinet (SCC) 24, for transmitting radio-frequency (RF) signals therebetween.
  • SCC Structured Cabling Cabinet
  • the PIU 16 allows the RF signals to travel from the SCC 24 to the television 20 without interference and with little or no signal loss.
  • the PIU 16 is, in this embodiment, a standalone unit but it could alternatively be incorporated into other devices (such as an RF modulator) .
  • the installed coaxial cable 22 couples the low voltage from the PIU 16 along its length to the remotely located SCC 24.
  • the installed coaxial cable 22 is then terminated within the SCC 24 onto an Amplified Splitter Extractor Module (ASEM) 26.
  • the ASEM 26 uses the low voltage from the conductors of the coaxial cable 22 to power its circuitry.
  • the ASEM 26 couples the low voltage from the PIU 16 to an Output Terminal 28 which provides a 12 V DC output and allows other modules/products located in the SCC 24 or in its proximity to draw upon this low voltage as a power source.
  • the ASEM 26 can either have a single output or multiple outputs with the same or varying power voltages.
  • the ASEM 26 can either provide the voltage in the form that it was transmitted from the PIU 16, or it can include circuitry to transform the power to a different working voltage prior to making it available at the Output Terminal 28.
  • the SCC 24 includes, in this embodiment, a computer hub 30 connected to a data patch panel 32: the computer hub 30 is connected - by means of its DC input 34 - to Output Terminal 28 and powered therefrom.
