FMUSER CZH518A-2KW 2KW 2000W Analog TV Transmitter For TV Station 4U Rack

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 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.
* 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.
