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. technical features AM 500 frequency range 87.5 ~ 108MHz operating class B input return loss 20dB input power 3 ~ 6W OUTPUT POWER 500W nominal efficency 70% approx. cooling Air forced power gain 19.2dB typical harmonics 55dB, typical > 60dB S/ N RATIO ( AM SYNCHRONOUS) > 50dB, typical > 55dB HARMONICS DISTORTION ( 75KHz deviaTion) < 0.05% , typical 0.02% HARMONICS DISTORTION ( 150KHz deviaTion) < 0.2% , typical 0.05% L/ R STEREO CHANNELS CROSSTALK < -50dB ( with external coder) 65dB ( ref.100% 400Hz) synchronous AM S/ N ratio > 60dB ( 75KHz dev. and 400Hz) Pre-enphasis 50 or 75ms internally selectable RF output impedance 50W asymmetrical ( N Female Connector) audio/ stereo input connector BNC Female audio/ stereo input impedance High-Z. 2KW SCA channel input connectors BNC Female SCA channel input impedance High- Z. 2KW remote control interface Serial RS-232 cooling Air forced ( axial blower) operating temperature range - 10 ~ + 45º C maximum relativa humidity 90% ( without condensation) AC power supply 110 / 240VAC, 47/ 63Hz Dimensions 2RU ( 19" rack) 410mm depth weight 4.8 Kg ( 10.56lbs)
