The EM 250 is a 250W FM transmitter made up of the EM 25 DIG or EM20/ 30 exciter and the AM 250 FM amplifier. This equipment includes a high-efficiency amplifier, LPF ( Low Pass Filter) and cyclical protections of: SWR, overdrive, over-consumption, over-power and temperature. The output power is externally adjustable between 0 and 250W.The EM 250 also incorporates a switching power supply that allows stable output power with input voltage from 90 to 260VAC.
