DESCRIPTION:

ETG5000 is the most advanced transmitter in the world market, in terms of electrical efficiency, compactness, lightness, ease of use, diagnostic, connectivity and wealth of operating data, protection strategies and optimization of performance, power supply flexibility.

Electrical Efficiency: The typical values of total efficiency, measured TO THE ELECTRICAL OUTLET vary from 70% to 72% across all the FM band. Means for transmitting at 5000W RF antenna, the ETG5000 need to consume power in electricity between 6944W and 7142 W. It means that in 24 hours at maximum power consumption it will settle between 166.66 kWh and 171.41 kWh. In this consumption are included: modulator, ventilationand RF power.

Compactness: the ETG5000 is only 4 units, and is 65 cm long from the front panel to the antenna connector, 70 cm including the handles on the front panel. In this space is all included. The cooling air is possible thanks to the very low value of dissipated power (equal to 2 kW on average).

Light weight: with its 45 kg, the ETG 5000 is the lightest in the world, with a power density equal to 111.1 W/kg. Easy handling, possibility of insertion in tight spaces. Ease of use: a full menu available on the front panel display allows the most novice user to access all the settings of the apparatus through a single control knob.

Diagnostics, connectivity, wealth of data: thanks to a huge data setting(all voltages, all the electricity for different MOSFETs, the temperatures for each power supply, the temperature of each MOSFET RF), the state of operation of the apparatus is comprehensively and accurately described. The operating status is easily viewed remotely with the ability to connect through SNMP, OMRON, Internet, SMS and Hyperterminal.

Protection strategies and performance optimization: ETG5000 is governed by the SW algorithms that optimize performance under all operating conditions, even extreme, to ensure continuity of service in respect of safety equipment. The protections are involved in a gradual manner allowing the transmitter to operate also in a fault conditions preventing propagation of the faults.

Flexible power supply: the ETG5000 has three independent switching power supply from "Heavy Duty" (the black box) that connects to a three-phase 400 VAC, for a single-phase to 230 VAC, for a three phase system without neutral to 210 VAC, 210 VAC to a two-phase network. The apparatus may continue to operate at reduced power, even in case of failure of a power supply (in case of failure of two of the three power supplies, the continuity of the service is no longer guaranteed even if possible in many
