2KW digital

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.
