40kW FM Transmitter High Efficiency
40kW FM Transmitter
The series belongs to the High Power VHF product family of FM Radio Transmitters fully solid state technology air cooled
The ELETEC 40kw is realised with last technology, that allows drastic decrease of the temperature to a sensitive reduction of the consumptions.
ELETEC 40Kw is a system of total quality thanks to a diagnostic remote, fast and capillary assistance, low consumptions, duration in the time and it is
easy to use.
Combining the basic form AMP5000 we have gotten transmitters from 5Kw to 40Kw in configurations from 1 0 to N 1. All the components of the series shared the same characteristics to the RF module, power supply, logics of control, systems of protection, derating, facility of installation and simplicity of setup. The advantages of the module systems are as follows:

All the components of the series shared the same characteristics to the RF module, power supply, logics of control, systems of protection, derating, facility of installation and simplicity of setup. The advantages of the module systems are as follows:
• All technological improvement on the basic product is directly transferred on the apparatuses of the serie
• Automatic diffusion of the knowledges and maintenance
• Interchangeability and independence of the each module base
• Common parts of exchange on the whole series
System of the power supply switching by PFC (380 V. three-phases), high efficiency.
