TELECOMMUNICATIONS PRODUCT SOLUTIONS e-terragridcom LMU Coupling Device The e-terragridcom LMU with compact design ensures easy maintenance and reduced installation space. Comprehensive stand-alone coupling device for PLC telecommunications The power line carrier technique uses the power line as the transmission medium for data transfer of voice, energy management and protection signaling of point-to-point PLC terminals by superimposing a modulated carrier frequency on the AC signal carried on the power line. The e-terragridcom LMU coupling device is designed to insert and extract PLC signals from high voltage power lines under an optimum impedance matching. SAFETY AND RELIABILITY OPTIMUM MATCHING TO POWER Insulated and weather-proof enclosure provides full protection of equipment and personnel with a compact design offering easy maintenance and high reliability LINE CHARACTERISTICS Matching characteristics that cope with all the impedances between PLC equipment and the power line coupling capacitor circuit COMPATIBLE WITH EXISTNG PLC SYSTEMS Without any additional accessories, the e-terragridcom LMU fulfils various configurations encountered in the power line technique.
