Definition of "Concentrator" |
A Photovoltaic module that uses optical elements to increase the amount of sunlight incident on a Photovoltaic cell. / An arrangement of photovoltaic cells that includes a lens to concentrate sunlight onto small area cells. Concentrators can increase the power flux of sunlight hundreds of times. / In the evolution of modern telecommunication systems there was a requirement to connect large numbers of low-speed access devices with large telephone company 'central office' switches over common paths. During the first generations of digital networks, analog signals were digitized on line cards attached to the central office switches. In an effort to reduce costs, it was decided to push this conversion closer to the customer premises by deploying small conversion devices in customer neighborhoods. These devices would combine multiple digital signals on a single link to a larger telephone switch, which would provide service to the customer. These devices were initially called remote concentrators or simply remotes. / VOC is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected. |
