The EM 500 is a 500W FM transmitter made up of the EM 25 DIG exciter ( or EM 20/ 30 exciter) and the AM 500 FM amplifier. This equipment includes two 300W high-efficiency amplifying modules, LPF ( Low Pass Filter) and cyclical protections of: SWR, overdrive, over-consumption, over-power and temperature. The output power is externally adjustable between 0 ~ 500W. The EM 500 incorporates a switching power supply that allows stable output power with input voltage from 90 to 260VAC.
