  ET10000 - 10000W ICEFET  FM TRANSMITTERS

All models are W.B. 87,5MHz - 108MHz and their frequency is changeable without adjustment.

The Transmitters are accessible from the front panel, the RF, control and power supply connections have been designed to ease the replacement of a module with no service interruption.

Every base module is completely redundant itself. The base module of this family is the E3500 amplifier with the
ETG exiters, all the constituents of the family share the same characteristics concerning RF modules, power supplies, control logics, protection systems, derating, and so on.

 

  • Highlights

  • ICEFET® This innovative Elenos application combines the very high yield of Mosfet with a maximum efficiency dissipator. The result is a drastic reduction of temperature and a consequent increase in MTBF, thereby allowing us to develop the smallest and lightest transmitters available on the market.
  • ALWAYS FUNCTIONAL Thanks to “SOFT FAILURE DESIGN”, efficient protection systems and redundancy of apparatus otherwise needed to eliminate "SINGLE-POINT-FAILURES”, Elenos transmitters are always «ON AIR» even under extreme work conditions.
  • IPC (Intelligent Power Control) Another exclusive Elenos application. IPC maintains constant output power within 2% of the defined value, regardless of fluctuations in supply voltage, RF piloting or charge conditions.
  • IPF (Intelligent Proportional Foldback) IPF is an intelligent system that varies the apparatus output power in relation to changes in charge conditions so that the transmitter can always function even under significantly variable charges.
  • BROAD BAND The declared technical performances of the transmitter are maintained across the entire 88-108 MHz band without the need for any kind of calibration. This means it is ideal for n+1 applications.
  • CONSTANT YIELD The supply voltage to Mosfet and Bias systems are both controlled to optimise yield at any frequency and output power level. This means low heating, high yield and consequent low operating costs.
  • NO IPA Elenos avoids using intermediate charge amplifiers to eliminate one of the redundancy bottlenecks frequently present in medium-high power transmitters.
  • EASY MAINTENANCE All components (RF modules, electronic control cards, fans, power supply units) are easily accessed from top and bottom sections and from front and rear panels.
  • SMS ALARMS/TELEMETRY Connection to a GSM modem ensures SMS notification of eventual alarms, faults and machine status. SMS also ensures inter-action with the transmitter. A remote PC can be used to maintain control and interaction of all transmitter operating parameters. The industrial standard Hostlink protocol ensures safe control of an enormous quantity of information for remote diagnostics.
  • WORLD-WIDE TECHNICAL SERVICE ELENOS is a producer of FM apparatus with one of largest distribution channels in the world. Every distributor is essentially chosen for the technical support it can offer to clients.
