3KW PDM MW AM Broadcasting Transmitter:High-frequency drive signal has outside stirs up and local oscillation two ways, automatic cut over local oscillation when outside stirs up without signal.The overall is suitable the three-phase AC 380V 50Hz power source, because uses the power feedback technology, when the supply voltage changes within - 10% ∼ +5%, the output may maintain basically invariable.The last stage merit puts modular design. The control section uses the digitization logic circuit, wants to keep the remote control, the telemeter connection, is advantageous for the user to carry on the computer networking and the brake transformation. May in addition according to the user request disposition microcomputer intelligence control system.The transmitter engine cases aluminum sheet passes the electric conduction oxidized, after the steel structure through the galvanization to spurt models, has good dustproof, anticorrosion measure, bear high humidity and temperature. Transmitters contour succinct sprightly, uses the international popular colors, the manufacture craft excellent. Each target surpasses the GB standard.The overall efficiency up to 70 %, reduce users electrical bill disbursement.The transmitter layout reasonable, high reliable, exempts maintenance, the working conditions in -10 ∼ +45oC can normal operate, may continual above 24 hours work in 90 % humidity situation.Timely after-sale service system and safeguard measure.This type already through the level scientific and technical payoffs appraisal, and has The State Administration of Radio Film and Television bureau product to enter the model which the net permit, the production certificate and National Wireless Communication Committee issues after due investigation to approve the card.Descriptions and Specifications:Frequency Range: 531kHz∼1602kHz willfully assignsTransmitter Type: Bring bilateral AM A3ELoad Impedance: 50ΩPower Output: ≥3KWCarrier Wave Frequency Stability: ≤1Hz dayModulator Type: PDMOutput Port Type: L36∼50KFSubcarrier Frequency: 72kHzAudio Input Impedance: balanced 600Ω, 150Ω, 50ΩAudio Input Voltage: - 10dBm∼ plus10dBmModulation Frequency Range: 50Hz∼ 8000HzFrequency Response: ≤±1dB 50Hz∼8000Hz m∼0.5Harmonic Distortion: ≤2% 50Hz∼8000Hz m≈0.9SNR: ≥60dB 1000Hz m≈1AM Degree Of Asymmetry: ≤2%Carrier Wave Fall: ≤3%Overall Efficiency: ≥70%Cooling Mode: Forced Air CoolingPower Source Supply: AC3-phase 380V -10% ~ +5% 50Hz±1HzConditions Of Use: -10 ∼ +45oC Operating temperature in the scope may continue workingWhole-Machine Dimensions: 750(W) Χ 1000(D) Χ 2000(H)mmWeight: 430kg
