Solid State Amplifiers
Generals. The TV amplifier TAI 3000AB gives 3000 Watts peak sync in continuous service. It is suitable for analog or digital TV broadcasting in the I band.
Broadband. The amplifier circuit is broadband, so it is possible to change the transmission channel without adjustments.
High efficiency switching mode power supply guarantees high reliability, low heat generation and energy consumption.
Modular assembly. The modular structure simplifies the maintenance, reduces the installation costs and spare parts investment.
High redundancy. The RF independent modules with their own separate power supply and combining system architecture assure high redundancy degree and uninterrupted service even in case of PA or power supply failure.
Electronic protection assures an affordable and stable operation protecting units against major fault conditions.
A front panel digital meter combined with LED indicators allows the user to check all the most important parameters of the equipment. The measures are visualized directly on the digital LCD display.
Meets or exceeds all international standards for safety and electrical requirements.
