Detailed Product Description

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.
