    ZHC518D-500W Digital TV Transmitter
     
     Introduction:
        This product adopts a new scheme design, and can be equipped with domestic or imported digital modulators that comply with DTMB national standard modulator, China Mobile Multimedia Broadcasting Television (CMMB) modulator, DVB-T European standard and other standards. Single, dual modulator configuration, automatic switching.
        This product has excellent performance indicators, designed with a large amount of power redundancy, and uses a high power FET (LDMOS) suitable for digital TV signal amplification for power amplifier components. The one-time synthetic power synthesizer developed by the company has the characteristics of small loss and small standing wave. The preamplifier ALC circuit ensures the stability of the output signal.
        This product has over-current, over-temperature, over-power and other protection properties. The main control touch screen displays the working status of the whole machine and the power amplifier components in real time. This product is mounted in a 19-inch high cabinet and is compact. Suitable for TV station digital TV broadcasting.
    Features:
    1. All solid state digital TV transmitter, 6-8MHZ bandwidth
    2. Predistortion correction, dual exciter automatic switching (optional)
    3. High linear LDMOS power amplifier, modular high gain power amplifier module, parallel switch power supply, high efficiency
    4. Computer remote telemetry remote control, networked interface and software
    5. Good man-machine interface, one-button automatic switch machine
    6. Multiple protection (overvoltage, overcurrent, overheat, large standing wave ratio...) High reliability, continuous operation for 24 hours
