    ZHC618F-5000W FM Broadcast Transmitter
     
    Introduction:
      The 5KW FM Stereo Transmitter (Hot Plug) is a high performance broadcast stereo stereo broadcast transmitter for professional broadcast radio coverage. Considering the high reliability of the transmitter, the transmitter is designed with redundancy in key parts in order to achieve long-term stable operation of the transmitter. Thanks to the hot-swappable construction, the components of the transmitter can be repaired and restored without downtime.

     Features:
    1. Large power margin: It is efficiently synthesized by four 1.5KW hot-swap modules, and four 2500VA hot-swap switching power supplies are connected to each other.
    2. Output power is stable: Intelligent automatic power control technology (AGC) is adopted to ensure that the output power does not change with the startup time and ambient temperature, and the power stability is controlled within 10W.
    3. Dual exciter configuration (optional): Intelligent automatic switching with dual exciters can further improve the reliability of the whole machine.
    4. Digital FM exciter: It adopts full digital CD-level FM exciter to directly receive digital audio signal (AES/EBU), and the listening effect is close to CD sound quality.
    5. User-friendly interface: It adopts 8-inch true color touch LCD screen to display various parameters in the machine in real time, without any training, it can be operated at the screen prompt.
    6. Complete protection functions: over power protection, over-reflection protection, over-temperature protection, over-voltage protection and over-current protection; and intelligently adjust output power when some power amplifier modules are faulty, maintaining maximum safe power broadcast, It also ensures that the fault will not expand.
    7. Real hot plug function: In any case, the power amplifier module and power module can be plugged and unplugged without stopping the machine, and the transmitter can be repaired and restored without stopping the machine.
    8. Timing automatic adjustment of output power: Through field setting, the transmitter automatically adjusts the output power at different times of the day, which brings convenience to the economic operation of the radio.
    9. Advanced remote telemetry interface: Access any parameters inside the transmitter via RS232/RS485 interface or TCP/IP network interface.
