DB Elettronica - FM Amplifiers

The latest FM transmitter series produced by DB Elettronica combine the COLD FETT technology of high efficiency, with latest generation devices, using high performances PFC filters for the AC/DC conversion.

This kind of technology allows the FM transmitters to reach very high levels of compactness and of energy efficiency with the use of traditional technologies, saving energy, having more manageability and reducing the spaces for the installation. The dimension of a 3 kW air cooled amplifier, in fact, is only 5Ux19" height while in the liquid cooled version it is 3Ux19" with a weight of only 18 kilos!


The redundancy in the power supply system is guaranteed by the use of AC/DC switching power supply units used in "OR" configuration, while the RF redundancy is assured by an "independent contribution" architecture that prevents the complete stop of the equipment even in case of multiple damages on amplification modules.

The power rates of FM solid state transmitters are from 30W to 1kW in the compact version (modulator included ) and up to 40 kW in air or liquid cooled HI-Power version.

Remote control and telemetry units are present on FM transmitters allowing a constant supervising of transmission parameters via internet (WEB SERVER option) or with a SMS to the customer (SMS option).
