Product Description

300W TV Transmitter

TV Transmitter UHF/VHF Power: 300W
Professinal designed for TV stations
Big LCD displays all parameters
Switched power supply
High reliability
Low price

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 500W transmitter is installed in one 19inch chassis; it’s suitable for medium or small 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.
