Product Description
TV transmitter
RF power: 10KW/5KW/3KW/1KW/500W/300W/100W
Frequency: VHF/UHF
System: PAL/secam/NTSC
Compatible: Digital/analog
Structure: Hot plug
High reliability
Low cost

Features:
The whole machine is single-channel, image with audio together.
The redundant configuration design can reduce the rate of inactive to zero.
The exciter redundancy design: The main exciter and its spare exciter can switch automatically (the spare exciter is optional). When the main exciter broke down, it can switch to the spare exciter uninterrupted.
The power amplifier redundancy design: Multiple amplifiers integrated; The modules of PA are high-consistency. These two exciters are the spare one with each other and can exchange easily.
The power supply redundancy design: Parallel current sharing power from multiple switching power supply; The computer can monitor power supply's working condition and adjust its working condition automatically.
Comprehensive protection measures can reduce the damage of equipments. This machine has protection about no video; VSWR is too large, overheating, over-stimulus, missing phase protection and lightning protection. The switch has protection about overvoltage, over current, under voltage, over temperature, short circuit and lightning protection.
All power supplies are switching power supplies; High efficiency, excellent regulator range, strong adaptable from the change of the external voltage.
Hot-pluggable design: Power amplifier and switching power are supporting the Hot-plug, it's easy to debug and maintenance; Improve the reliability.
The fan is built-in the chassis, the transmitter has a compact structure and a beautiful shape.
