Is produced in a wide range of power: 30W (30 watts), 50W (50 watts), 60W (60 watts), 100W (100 watts), 150W (150 watts), 300W (300 watts), 500W (500 watts), 600W (600 watts), 30W to 5000W ( watts) and 1200W (1200 watts).
The PCB Boards and the wiring are fully tropicalized by a specific coating for electronic assembly.
Air Filter and Tropicalization provides high protection to the internal components when the equipment is installed on places with dust, humidity, salt and pollution.
active power components such as LDMOS or unbalanced power resistors are mounted on a copper carrier to improve heat dissipation and greatly facilitate maintenance, in fact in cases where LDMOS is mounted directly on the heat sink, it causes high heat sink dissipation and it becomes almost impossible to heat the weld.
The equipment is housed into a compact rack mountable 2 Unit Aluminium cabinet.
An exclusive design of the air flow inside the transmitter guide the air into aluminium ducts avoiding contact with the electronic components.
Every component that produces heat is mounted on a heat sink.
Air passes exclusively into the aluminium heat sink avoiding contact with the electronic components.
There are two kinds of protection: Fast Hardware Protection and Soft Software Protections
In some conditions, like a short-circuit on the antenna or coaxial cable, the protection must be hardware and act in few nanoseconds. In fact, the software in this case is not fast enough to grant the protection of the equipment.
When the fault condition is soft, like the increase of VSWR caused by snow or humidity, a software protection can be use.
On the ECO series of FM Transmitter are implemented both: Fast Hardware Protections and Soft Software Protections.
The software protection reduces the output power without on-air interruption, keeping the RF devices always within the safe operating parameter.
The transmitter is protected in case of:
Beyond the Hardware or Software protection, the transmitter is designed to be rough itself, to keep it functioning perfectly even in the worst case of operating conditions.
To achieve this, the important components of the transmitter are over-dimensioned or with hardware protected:
6th generation LD-MOS High Efficiency and VSWR 65:1.
Over-dimensioned switching power supply with PFC (Power Factor Corrector)
Over-dimensioned Heat Sinks and Fans
Integrated AC Mains filtering
Integrated lightning protection
Integrated overvoltage spikes on the mains protection.
ECO use Solid State RF power devices, 6th generation LD-MOS High Efficiency and VSWR 65:1 to deliver high reliability and low energy consumption.
The high Efficiency is keep constant at any power level thanks to an intelligent algorithm that control the Voltage Power Amplifier and the Bias to obtain maximum efficiency at any frequency and at any output rated power.
The RF module amplifier design and the output filter broad band keeps optimum performances on spectral purity without needing of tuning.
The output power can be programmed depending on time for energy consumption optimization management.
