ZHC618F-1000W/M FM Broadcast Transmitter (Cabinet)
Introduction: The FM stereo broadcast transmitter (modular) is based on a new digital FM stereo broadcast exciter and is modularly combined by an FM exciter, a RF power amplifier, and a power supply. This machine structure facilitates maintenance and repair of the transmitter, and the configuration of the active and standby dual exciters has improved the reliability of the transmitter. The universal roller is equipped at the bottom of the cabinet to facilitate the movement of the equipment. Features: 1. Modular design concept, each functional module adopts modular assembly for easy maintenance and repair 2. It consists of FM exciter, RF power amplifier module and switching power supply module 3. Redundant configuration of active and standby FM exciters can be used to reduce the off-air rate 4. With TCP / IP, SMS cat, RS232 communication interface, can use computer management and monitoring 5. Switching power supply with overvoltage, overcurrent, undervoltage, overtemperature, short circuit, lightning protection, etc. 6. With VSWR, over-excitation, phase loss and lightning protection 7.
