Audited Supplier 10KW FM Broadcast Transmitter (Modular)
Technical features:
1. Transmitter structure: The transmitter consists of two 5KW power amplifier modules that can work independently and have their own output filters.
Efficient synthesis; each power amplifier module is a 19-inch standard chassis, and the height should not be greater than 4U.
2. High working efficiency: Using the latest high-efficiency LDMOS power amplifier tube, the full-power RF efficiency is as high as 70%.
3. Stable output power: using intelligent automatic power control technology (AGC) to ensure that the output power does not follow
The power stability is controlled within 10W.
4. High reliability of the power supply: 8 pieces of 3.6KVA hot-swappable switching power supplies are used in parallel for current-sharing power supply, and the power supply capacity is rich.
Large margin.
5. Digital FM exciter: It adopts fully digital CD-level FM exciter, which can directly receive digital audio signals.
number (AES/EBU), the listening effect is close to CD level. It can also be matched with other high-quality exciters.
6. Friendly man-machine interface: 8-inch true-color touch LCD display, real-time display of various parameters in the machine
(Including the current of each power amplifier tube); no need for any training, it can be operated under the on-screen prompts.
7. Complete protection functions: with over-power protection, over-reflected power protection, over-temperature protection, over-voltage protection
and over-current protection; and can intelligently adjust the output power when some power amplifier modules fail, not only maintaining the maximum safety
Full power broadcast, but also to ensure that the failure will not expand.
8. Excellent lightning protection performance: high-quality lightning protection devices imported from Germany are used to protect the power supply of the whole machine.
9. Timing automatic adjustment of output power: through on-site settings, the transmitter can be automatically adjusted at different times of the day
The output power brings convenience to the economic operation of the radio.
10. Advanced remote control telemetry interface: access the transmitter through RS232/RS485 or interface TCP/IP network interface.
