    Product Discription:
    The AM 500 is a high-performance 500W FM amplifier, developed with MOSFET technology.

    It includes an elliptic LPF (Low Pass Filter) with high-attenuation in the harmonic frequencies and its sophisticated power supply unit with a DC-DC converter guarantees an optimal working with mains voltage fluctuations between 90 and 260V without output power variations.

    The most relevant parameters can be visualized in the LCD display: forward and reflected power, overdrive, module 1 current, module 2 current, power supply 1 voltage, power supply 2 voltage,etc. And the equipment also provides cyclical protection system to protect the amplifier against forward and reflected over-power, overexcitement, over-current, over-voltage and excessive temperatures.

    The 2 independent 300W amplifying modules are combined and mounted on a high-performance heat-sink, so that the transistors work in optimal thermal conditions even in really hot environments.

    Furthermore, the AM 500 provides a telemetry output in order to get information about internal parameters of the amplifier.
