The new DFM LC HPA 10K-40K transmitter of the Ecostone family is a liquid-cooled technological platform capable of providing an FM output signal up to 40kW. Extremely compact and efficient equipment – both the transmitter and the cooling system are enclosed in a standard 19 “rack, with optimized energy consumption.The system integrates a hydraulic cooling system with pipes inside the amplifiers, powered by a redundant hydraulic pump included in the Rack, to maintain operating temperatures in a stable manner even in the worst environmental conditions.
The DFM LC HPA 10K-40K is equipped with a complete set of audio inputs and an internal GPS receiver (1 pps and 10Mhz) for the necessary synchronization. An intuitive local interface displayed on the LCD and controlled through a rotating knob allows real-time monitoring and configuration of the equipment parameters.
Remote control and monitoring options available.
