Digital and analog compatible FM transmitterKFT-Ⅲ series all solid state analog FM transmitter, is a new generation of FM transmitting equipment designed by our company. The product was released in 2003. The broadcasting system compliant with GB/T4311 (Technical Specifications for FM Sound Broadcasting at VHF), and the main parameters are better than GY/T169 (Technical Specifications and Methods of measurement for FM broadcasting transmitters at VHF. The structure of the equipment is reasonable, with advanced technology, full functions and high automation level; it is an ideal product for large and middle scale FM broadcasting stations.
Main Features:
1. All solid state circuit design, excellent stability and high reliability.
2. Support protection functions against overload, over-heat, and high VSWR, and lightning protection systems.
3. Built-in MPU monitoring control, LCD screen display, friendly HMI interface.
4. RS485 parallel interface for remote metering and remote control;
5. Adopts forced air cooling, small power consumption and low noise;
6. Uses standard cabinet design with module structure, nice appearance and small size.
7. Redundancy design.
