Product Desciption
ZHC518A-3000W Analog TV Transmitter
Overview:
This product is the all solid-state Single-channel TV Transmitter, it adopts professional TV exciter, and it can use the single/duel exciter configuration, switching automatically.
This transmitter has a variety of linear and non-linear pre-correction function, carrier frequency offset, and precision bias (with external precision reference source) function.
It can prefabricate and control the half-power output, and it has remote control telemetry interface.
The power amplifier used LDMOS FET, the analog and digital are both compatible, and it used high-quality switch parallel power.
The power amplifier and power supply are both used hot-plug devices.
The power loss and standing wave of the one-time synthesis power combiner is small.
The module of power amplifier display the working parameters in real-time.
The whole machine has the protection of over-current, over temperature, over power and over-standing wave ratio.
The master touch screen displays the working parameters of the whole machine and the module of power amplifier (PA) in real-time.
The 2KW transmitter is installed in one 19inch chassis; it's suitable for all-levels of TV station.
Features:
The whole machine is single-channel, image with audio together.
The management and monitoring are intelligent and on network, it has the external PC interface.
It has the technical data detection, monitoring systems and full-featured computer control software with auto-diagnostic function. All technical parameters can be read through the LCD display panel.
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.
It adopts modular design concept.
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.
Overall performances:
1. Working frequency: VHF/UHF Channel arbitrary choice
