VOS 137/RA
VOS 138/RA
 House connection amplifiers for modern HFC networks
 VOS 137/RA - locally powered
VOS 138/RA - remotely-powered through RF input
(auto-supply)
VOS 139/RA - remotely-powered
 State-of-the-art GaAs-MMIC technology
 Very high output level at a favourable energy balance
 Highly efficient switched-mode power supply unit
 New innovative operational concept:
-Easier levelling due to rotational switch, wide setting range
(20 dB), small increments (1 dB)
-Basic configuration via bridging plugs
-Device settings can be reproduced exactly
 Test sockets (F-type connectors):
-Bi-directional on input (connectable)
-With directional coupler on output
 Internal LED function display
 Surge absorbers on input and output
 Comprehensive remote feeding concept (VOS 139/RA):
-Remote-feed current: max. 5 A
-Remote-feed voltage: 32-65 V~
-Remote-feed options: Through RF input and output or
through local connection (power passing)
 Conform to: EN 60728-11, EN 50083-2 and EN 60065
 Die-cast housing with F-type connections (VOS 137/RA,
 Insert position for additional functions in forward path
(e.g. de-emphasis, system equalizer)
 Variable interstage gain 40/34/30 dB using bridging plugs
(delivery status: 34 dB)
VOS 138/RA) or PG 11 connections (VOS 139/RA: cable
fittings must be ordered separately, not included in delivery
scope)
 For use in weather-protected locations
 The amplifiers comply with the EMC directive 2004/108/EC
 Diplexer bridgeable (Band I operation possible without
return path)
and Low-Voltage Directive 2006/95/EC applicable at the
time of shipping
 Classification to KDG 1 TS 140: Type D (4.4)
 Return path (active/passive/switched-off) with diverse
built-in setting options
