Cooling Due to its high efficiency, the transmitter generates less heat requiring less cooling. The cooling is handled by an optimized air cooling system that incorporates an ultra-reliable internal blower, designed for reliable operation up to 50 C peak temperature. The cooling system features low heat dissipation to the transmitter room and low acoustical noise. The front-accessible power mains control system provides AC and raw DC power distribution, to the various power supply units, via distributive and protective circuits. The exciter module has its own dedicated power supply.
All power supplies are fault-protected for overvoltage, overtemperature, and overcurrent.
The transmitter can withstand more than 6 kV transient testing to assure highest resistance to lightning and other discharges. The power amplifier module features ultra-redundant internal design due to the use of multiple amplifiers in parallel and an isolated power combiner. The power amplifier module is self-protected against overtemperature, overcurrent, overdrive, and high reflected power. The transmitter is ruggedly designed to ensure safe operation even in harsh environments. IS09001 certification assures the quality of Itelco transmitters in every step from design to production.
