10KW FM transmitter station is an excellent best fm transmitter for professional radio station.It is reliable and high performance.It consists of center control module,double digital exciters,12 pcs hot-plug 1KW FM amplifer modules,12-way combiner,a perfect BPF and 10 pcs hotplug 2500VA switched power source modules.
FM transmitter stations

1. Twelve Units 1KW hotplug RF power modules.Total output power is extremely stable thanks to AGC(Automatic Gain Control).
2. Ten units 2.5KVA switched power supply modules working parallel.
3. 12-way High efficiency combiner with patent technology.
4. Two All-digital 30W exciters with switcher used to drive each module directly.
5. Analog and digital(AES/EBU) audio signal input directly.
6. 8-inch Color LCD with touch panel displys all the parameters in real time.
7. Five kinds of protect method by MCU, like over Pf,over SWR,over Temp,Voltage,Current.
8. Real hot-plug structure,the modules can be repairing at non-stop condition.
9. RS232/RS485 Communication interface ready for remote system.
