Elenos ETG: Thermo-controlled and servo-assisted fans

The new series of transmitters ETG 2, 3.5, 5, those who have integrated the modulator, and the ET series, have a good smart fan control. They are long life and DC and managed by a hardware logic to allow the rotation even at lower or higher regimes speed than the standard of rotation. Significant advantages: speed is metered in terms of the actual needs of the apparatus and according to the temperature of the cabin, the fans are used less at high speeds to prolong its life, less rotation of the fans means less noise and less power consumption. And if it gets too hot in location, the unit remains onair untill reaching 45 °C in the site, if the temperature increases, the apparatus increases the speed of the of the fans up to 120%, and if it is not sufficient it derates its power output to keep the area safe for devices and power supplies. In any case, the device never goes out, but works at reduced power .
