FOURTH SERIES MEDIUM POWER

FOURTH SERIES MEDIUM POWER

TRedess Fourth Series Medium Power is a family of Air-Cooled UHF Transmitters up to 2.4 kW, bringing together maximum flexibility, high efficiency based on the use of the latest Ultra-Wide Band Doherty technology, compact design, reliability and very smart installation and operation, fully oriented to minimize the rack space and the total cost of ownership.

TRedess Fourth Series Medium Power covers DVB-T, DVB-T2, ISDB-T and ISDB-Tb standards, for both MFN and SFN networks. Transmitters can work in Regenerative Transposer mode.

 

The units include complete local and remote control, plus all the optional functionalities that the particular scenario may need, such as GPS receiver, satellite receiver, (DVB-S/S2), terrestrial signal input (DVB-T/T2), and even 1+1 functionality. N+1 redundancy is also available.

 

Thanks to Ultra-Wide-Band Doherty technology important cost reductions in energy consumption can be achieved without impacting in a truly smart operation and maintenance.

Advantages & Benefits

The Power amplifiers based on the Ultra Wide Band Doherty technology allow to reach very high efficiency levels, allowing a very significant and decisive reduction in the cost of energy consumption.
The big advantage of the use of UWBD technology is the fact of allowing to perform a change of the RF channel without any need of adjustment or HW modification in the power amplifier, what implies a cost reduction and simplification of the spare parts man
Very significant space usage reduction, hence the costs for renting the transmitter space at the site.
High system reliability due to the redundancy systems 1+1 and N+1.
Very simple local and remote control of the Transmitter via the very intuitive and friendly Web interface the local LCD display.
High system reliability also due the available Dual Drive configuration.
High operation flexibility due to several types of inputs available (RF, ASI, IP, SAT..)
Space and cost savings due to the built-in (DVB-S/S2) satellite receiver.
