The SATURN line allows to implement low/medium/high power broadcasting sites with optimal space requirement. In a single 42U 19" rack a DAB+ Transmitter up to 2.3kW before the output mask cavity filter can be delivered. Higher Powers are available upon customer’s request. The operating temperature
of the power amplifiers is optimally guaranteed by
an extremely noiseless forced-air cooling system, simultaneously enabling total reliability and compact rack layout. The amplifier drawers are equipped with high- efficiency AC switching power supplies, designed to guarantee a power factor close to one with every load condition. The high modularity, high power density, low weight, fully comply with the most demanding installation requirements. Furthermore, the high efficiency allows a very low and easy predictable operating cost. Thanks to the unsurpassed Digital Precorrection system of the SATURN DAB+ exciter and to the high linearity of the amplifiers, achieved with the use of latest-generation 50V power devices technology, the coverage and quality performance of the radiated DAB+ signal are simply excellent.
A careful design, approached with strongly oversized components and parts and guaranteeing the presence of
at least two items for each critical component, allows an intrinsic “native redundancy” concept (Power Devices, Power Supplies, Cooling System) saving space and maximizing MTBF values. The presence of a central Control Unit that collects all the operating parameters from the amplifiers and from the antenna system provides a single control point able to access to all power devices currents, power supplies voltages, temperatures of the heat sinks, amplifiers output powers together with the RF power reading of the output antenna system. A multifunction display on the Control Unit allows to monitor in real-time all the operating parameters of the DAB+ Transmitter. All the transmitter in this series are remotely controllable by wired telemetry connection, by serial communication, or with Web Server and SNMP interface.
Each transmitter comes with automatic seamless switching function between the ETI and EDI inputs in all combinations in SFN mode.
