SPECIAL FEATURES


  • ■ House connection amplifier for modern HFC networks
    ■ Remotely fed via RF input (auto-supply)
    ■ Latest GaAs-MMIC technology
    ■ Very high output level with favourable energy balance
    ■ Highly efficient switched-mode power supply unit
    ■ New, innovative operational concept:
    ■ - Easy levelling using rotary switch, large setting range (20 dB), small step width (1 dB)
    ■ - Basic configuration using jumpers
    ■ - Exactly reproducible device settings
    ■ Insert position for additional functions in forwards path (e.g. de-emphasis, system equaliser)
    ■ Amplification using interstage attenuation with switchable jumper 40/34/30 dB (delivery status: 34 dB)
    ■ Bridgeable diplexer (I-band operation without return path possible)
    ■ Return path (active/passive/disconnectable) with various setting facilities built-in
    ■ Classification in accordance with KDG 1 TS 140: Type D(4.4)
    ■ Test sockets (F connectors):
    ■ - Two-way at input (connectable)
    ■ - With directional coupler at output
    ■ Internal LED function display
    ■ Voltage surge conductor at input and output
    ■ Compliant with: EN 60728-11, EN 50083-2 and EN 60065
    ■ Die-cast housing with F connectors (VOS 137/RA, VOS 138/RA) or PG 11 connectors (VOS 139/RA: order cable fittings separately, not included)
    ■ For use in locations protected from weather
    ■ The amplifier complies with the requirements in the EMC Directive 2004/103/EC and the Low Voltage Directive 2006/95/EC applicable at the time of delivery
