Calrad's 72-501 USB Powered Keystone Insert is an expandable system that provides a simple and inexpensive solution for powering USB type devices such as iPads, iPhones, etc. remotely using standard Cat5e, Cat6 UTP cabling, conversion of (12-15Vdc to 5Vdc). Several units can be cascaded in series or parallel and powered from a single high current power supply or ran independently using a single low current power supply. 4 Position terminal blocks provide 12Vdc in and out for easy connection to a local wall plate or to be extended to additional wall plates. The 72-501 Keystone inserts incorporate intelligent circuitry to provide the proper charging current for any device attached, up to 3 amps max.
Please Note: The output current depends on the distance of the Cat5e, Cat6 cable and the amount of pairs used. 15Vdc power supplies will provide more current over longer distances.
