ISTRUZIONE IMPIEGO
AMPLIFICATORE FINALE LARGA
BANDA
Amplificatori finale larga banda (47÷862 MHz) in
configurazione push-pull con un ingresso e una uscita. Il
modulo, su meccanica serie K, si monta su barra DIN (art.
KD100), vedi pag. 2. I KW20D e KW35D vanno alimentati
con un alimentatore della serie KP.. attraverso lo spinottino
rosso.
COLLEGAMENTI E REGOLAZIONI
Il connettore F posto sopra il modulo é l’ingresso del
segnale da amplificare, mentre il connettore posto sotto il
modulo é l’uscita amplificata.
Prima di effettuare l’installazione é necessario collegare
l’impianto a terra,in particolare la barra DIN, a regola d’arte
come previsto dalla norma CEI EN 50083-1. Per installare
l’amplificatore occorre operare nel seguente modo:
agganciare l’amplificatore alla barra DIN senza
alimentarlo;
effettuare i collegamenti d’ingresso e uscita con i
cavi coassiali regolarmente intestati;
infine collegare il modulo all’alimentazione (12V).
In caso di disconnessione, anche della sola uscita,
procedere con la sequenza inversa scollegando per prima
l’alimentazione.Agendo sul trimmer “GAIN ADJ” si regola
il guadagno. La spia “ON” indica la presenza di tensione
12V. Il trimmer “EQUALIZER” permette di inserire un
TILT regolabile (0 a 20 dB) nella banda 47÷862 MHz per
compensare le perdite del cavo (vedi fig. 1). Il livello di
uscita max. (con 2 canali TV amplificati) é di 125 dBµV.
Attenzione: Se avete più canali TV da distribuire, bisogna
diminuire il livello massimo di uscita di 3 dB ad ogni
raddoppio di canali amplificati.
Esempio:
N° canali Livello massimo di uscita
2 125
4 122

BROADBAND AMPLIFIER
USER MANUAL
KW20D e KW35D are broadband amplifier (47÷862 MHz),
made with a push-pull configuration. There is a single input
and a single output, both equipped by "F" connector. The
module is fixed to a DIN bar, (art. KD100) see page 2. The
KW20D and KW35D are powered by a KP.. power supply
unit, using the red plug-in cable.
CONNECTIONS AND ADJUSTEMENTS
The “F” connector on the upper side of the module is the
signal input. The “F” connector on the lowest side is the
signal amplified output.
Before installing the amplifier, it is absolutely necessary to
bond the system, expecially the DIN bar, according to the
CEI EN 50083-1.
Operate in the following way to install the amplifier:
fix the amplifier to the DIN bar without powering it;
connect the input signal and the output cable to the
amplifier;
connect the amplifier to the power supply.
To disconnect the amplifier, even only to check the output
level, operate in the inverse order, unplugging the power
supply as a first step.
The gain value can be adjusted by using the “GAIN ADJ”
trimmer. The led “ON” is lit when the module is working.The
“EQUALIZER” trimmer allows to insert a TILT adjustment
(0 to 20 dB) to equalize the cable losses (see pic. 1).
The max. output level is 125 dBµV (for 2 TV ch. amplified).
Attention: If there are more than two channels to ditribute,
the max. output level must be decreased of 3dB to each
doubling of the amplified channels.
Example:
N° ch Max output level
2 125
4 122
8 119
