DAM 10KW Digital MW AM Broadcasting Transmitter
Each target surpasses a grade machine standard. Its prominent features are as follows:A. Already proved the consummation reliable lightning protection circuit, finished you to damage the machine to the thunder stroke worrying.B. Nimble control mode. Besides the aircraft control system, may select and match the computer control unit too. In order to realize fixed time open, close down, data record, memory, graduation monitoring functions etc.C. Improved cycle modulation techniques. The new encoding method causes when the transmitter works, various merit put the module break over time basically balanced, avoided the raw mode merit put module operating time difference to be big, gives off heat non uniform shortcomings and so on the.D. The essential primary device uses import, selects strictly component pass. To possibly creates the breakdown connector, uses gold plated craft or import, as merit puts board and plug, main power three phase rectification entire bridge, merit puts tube, integrated circuit, plug and so on, guarantees under adverse circumstance does not rust away in the high temperature humidity, the work is reliable.E. May select specially made the audio frequency processing unit.. This aircraft provided match develops specially is suitable different antenna bandwidth audio frequency processing unit, which can effectively raise AM of the transmitter. and reduce possibility of the signal engine off which flushes creates.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 :Transmitter Type : MW 100 percent Solid StateFrequency Range : 531kHz~1602kHz , specified by customerCarrier Wave Frequency Stability :≤1HZ/dayPower Output : ≥1~10KW three preset power voltage level available with parallel operation capabilityOutput Impedance : 50ω non balanced or specified by customerOutput Port Type : L52~50KFRF Harmonic & Miscellaneous Emission : ≤50mWTransmitter Type : Bring bilateral AM A3EModulator Type : DAM Digital Amplitude ModulationCarrier Wave Fall : ≤2 percent 1KHz m≈1Audio Frequency Response :≤1dB 30Hz~10000Hz m≈0.5Audio Harmonic Distortion : ≤1 percent 5~10KW m≈0.95 30~10000Hz≤5 percent 1~5KW m≈0.95 30~10000HzSquare Overshoot : ≤1 percent 400Hz m≈0.8Square tilt : ≤3 percent 40Hz m≈0.8SNR : ≥60dB usually 65dBAM Degree Of Asymmetry : ≤0.5 percent m≈100 percent f≈1KHzPositive Peak Modulation Capability : 140 percent of positive peak at 10KWAudio Input Voltage : minus 10dBm~ plus 10dBmAudio Input Impedance : balanced 600ω 150ω 50ω electsInput Power : AC 3 phase 4 wire 380V±10 percent 50Hz±2HzPower Factor : 0.98Overall Efficiency : ≥85 percentRemote Control Port : availableOperating Temperature : minus 10~ plus 45°C The upper limit should be 2°C lower for each 300m increase of altitude, provided the altitude is more than 2000mOperating Humidity : ≤90 percent no condensingCooling Mode : Forced Air CoolingWhole Machine Dimension : 1830W x 1980 H x 830 DmmWeight : 750kg
