This type technological advance, reasonable prices, and fine performance price compared to, redundant reliability, high efficiency, is ideal choice which the user renewal, high quality broadcast. This type uses the digital AM technology is extremely mature, in recent years in the domestic high power WM transmitter transformed has used this technology, the routine maintenance facilitated extremely quickly, once appeared fault to be able to restore promptly broadcast, its maintenance cost extremely was low, the use merit put manages IRFP360 only then several dozens Yuan prices. And its control section is concise, convenient, and clear.The control section uses the digitization logic circuit, double color photo tube compose 28 test points, the aircraft may dispose liquid crystal display microcomputer control unit, not only can complete all controls, demonstration, alarm function, but can direct the computer connection, constitutes the microcomputer supervisory system. This aircraft over voltage, the overflow, over temperature, the antenna unbalance as well as other essential spot condition wrong have protection. Or reduce power use, or switches off the transmitter, may broadcast safely.The transmitter has frequency source input port which the wave synchronization actuator provides effective value 1V, with this aircraft crystal oscillator frequency source automatic cut over, the frequency source which the synchronized actuator provides primarily use.Descriptions and Specifications:Transmitter Type: MW 100percent Solid StateFrequency Range: 531kHz∼1602kHz, specified by customerCarrier Wave Frequency Stability: ≤1Hz/dayPower Output: ≥10∼115KW three preset power voltage level available with parallel operation capabilityOutput Impedance: 150ω, 50ω or specified by customerOutput Port Type: 4inch flange Cable ConnectionRF Harmonic and Miscellaneous Emission: better than related regulations of FCC and CCIR StandardTransmitter Type: Bring bilateral AM A3EModulator Type: DAM Digital Amplitude ModulationCarrier Wave Fall: ≤1percent 1KHz m≈1Audio Frequency Response: ≤1dB 30Hz∼10000HzAudio Frequency Distortion: ≤1% m≈0.90 30∼10000HzSquare Overshoot: ≤1% 40Hz m≈0.8Square tilt: ≤3percent 40Hz m≈0.8SNR: ≥65dBAM Degree Of Asymmetry: ≤0.5%t ≈100% ≈1KHzPositive Peak Modulation Capability: 135% of positive peak at 100KWAudio Input Voltage: minus10dBm∼plus10dBmAudio Input Impedance: balanced 600ω, 150ω, 50ω electsInput Power: AC 3 phase 4 wire 380V±10percent 50Hz±2HzPower Factor: 0.98Overall Efficiency: ≥85%Remote Control Port: availableOperating Temperature: -10 ∼ +55oCThe upper limit should be 2oC lower for each 300m increase of altitude, provided the altitude is more than 2000mOperating Humidity: ≤90%, no condensingContinuous working hours: More than 24 hoursCooling Mode: Forced Air CoolingWhole Machine Dimensions: 3964(W) x 1030(D) x 2060(H)mmWeight: 3000kg
