This new series of television transmission equipment available in 20 kW p.s. power output is based on a structure of independent RF amplifiers connected in parallel in order to assure full redundancy and substantial reliability.
The technology applied provides "hot-swappable" amplifiers to allowmaintenance operations without interrupting duty.

The reduced internal wiring makes these units easy to install andmaintain, and even minimizes the probability of failure achieving highMTBF levels.
A redundant cooling system ensures high performance of transmittersalso in the case of air extraction fan failure.

A serial bus collects all operational data from each system componentand displays them on local control panels, or to remote control systemsthrough interfaces requested by the customer.

The high quality of the circuits allows these units to be used for thetransmission of digital signals by simply substituting the exciterwithout the necessity of calibrating or regulating the equipment.
