Broadband Indoor Distribution Amplier / Central Amplicadora - DTKom Series

Refs. 451280, 451281

Description

The DTKom Series Ampliers are professional quality, completely self­contained, two way broadband indoor distribution ampliers designed
for multi-channel RF distribution systems where the input source is a
cable drop or the output of a MATV/SMATV/CATV headend. The Ref.
451280 is a high output level, power doubling amplier, with an RF
bandwidth of 1002MHz, equipped for 2-way operation with a 42/54MHz
split that can operate in passive or active return congurations.

The ref. 451280 and 451280 have an user selectable gain of 30dB or 40
dB. It has 20dB attenuator-slope control and 10dB regulator-tilt control.

It has a return gain of 28dB when in active mode and 10dB attenuator.
The gain and slope controls are located on the front panel for easy set-

up and adjustment with the provided tool. Two -20dB test points are
provided to permit testing without interruption of service.

The DTKom Series ampliers incorporate a built in switched 120/230V~
power supply and are characterized by their exceptionally low power
consumption for a long and trouble-free operating life. The cast Zamak
chassis has been optimized to be compact and easy to install, while at
the same time providing excellent heat dissipation, allowing operation
at high ambient temperatures with no degradation of performance/
reliability.

Front panel variable reg. and tilt controls (10dB) for easy adjustment.
Two-way capability with a user selectable active/passive return path.
Power doubling technology for distortion-free, high output level

operation.

Externally accessible -20 dB input/output test ports provide

convenient in-service performance monitoring.

Optimized consumption: Approx. 20% less when congured as

Descripción

La Serie Amplicadores DTKOM contiene centrales profesionales de calidad,
en las que se combinan dos amplicadores de banda ancha independientes
para una distribución interior. Esta Serie ha sido diseñada para sistemas de
distribución multicanal RF, en los que la entrada puede ser la bajante princi­pal de cable o la salida de una cabecera MATV/SMATV/CATV. La ref. 451280
es un amplicador de gran potencia y alto nivel de salida con un ancho de
banda RF de 1002MHz, con capacidad para funcionar en dos bandas sepa­radas en 42/54MHz. El retorno es congurable, pudiendo ser activo o pasivo.

Las ref. 451280 y 481281 ofrece una ganancia de 30dB-40dB, seleccionable
por el usuario. Dispone de atenuador-ecualizador 20dB, y de regulador-pre­acentuador 10dB.

El canal de retorno gana 28dB en modo activo. Dispone de atenuador 20dB.

Los controles y switches están situados en la parte frontal del amplicador,
fácilmente accesibles. Se dispone de test entrada-salida a -20dB para testear
el equipo en funcionamiento.

Los amplicadores de la Serie DTKOM integran una fuente de alimentación
conmutada de 120/230V~ de bajo consumo que alarga la vida útil del equi­po. El chasis, realizado en Zamak, resulta muy compacto y fácilmente insta­lable. Además, proporciona una excelente disipación de calor, permitiendo
su funcionamiento en entornos con temperaturas elevadas sin que su rendi­miento o abilidad se vean degradados.
