ZHC618F-10KW FM Stereo Transmitter

ZHC618F-10KW is an excellent FM stereo transmitter for professional radio stations. It is Hot-Plug design, high reliability and high Performance. It consists of center control unit (CCU), double exciters, 8pcs hot-plug 1.5KW FM amplifier modules, 8-way combiner, a perfect LPF and 4pcs hot-plug 5000VA switched power supply modules. This can be repaired without turn off entire transmitter.

 

 

FEATURES

Fully Large Power: 8pcs 1.5KW hot-plug RF Amplifier modules combined high efficiently; Maximum Output Power is 11KW. It uses the new high-efficiency LDMOS Transistors, the full RF output power can reach 70%.

 

Fully Power Supply: 4pcs 5000VA switched power supply modules are working in parallel. It can provide large redundant power capacity.

High-performance Low Pass Filter which can minimize unwanted emission.

 

Output Power Stable: Total output power is extremely stable by AGC (Automatic Gain Control). Ensure the output power would not change with the boot time and ambient temperature, power stability is less than 10W.

 

Dual-Exciter: Two exciters (DSP+DDS) with automatically changeover switcher, increase entire transmitter stability.

 

● Analog and Digital (AES/EBU) audio signal input directly; Hearing similar to CD.

 

8-inch Color LCD with touch panel displays all the parameters in real time.

 

Intelligent protection functions by centre control module, like Over Forward Power, Over SWR, Over Temperature, Over Voltage, Over Current. It can adjust output power intelligent, keep the maximum safe output power and keep fault not expanding.

 

Best dustproof performance: All inlets are made of high-quality filters which can filter out dust in the air to keep stability of transmitter.

 

Best lightning protection: high quality lightning protection SPD from Germany for the whole power supply.

 

Real Hot-Plug structure: the Amplifier modules and Power Supply modules can be repairing at non-stop condition in any case.

 

Timing automatically adjusts the output power: After setting, the transmitter can automatically adjust the output power at different times of the day, convenient for economical radio broadcasting.

● Advanced Remote Telemetry Interface: RS232/RS485 or TCP/IP Internet Communication interface is ready for remote control system which can read all detail parameters from transmitter.
