DHE post amplifier art. 695004475 Housing 2HE with redundant power supply, art. 695004481
Description: The broadband post amplifier DHEVV-14 is specially designed for the amplification of signals in headends. The total unit is placed in a 2 RU 19” housing. The amplifier is suitable for amplification of QAM signals in the frequency range 85-862 MHz. The amplifier is provided with a lowpass filter (85-450 MHz). By activating the filter by means of the internal modules the pass band can be fixed. The gain of the amplifier is 14 dB. Optional the amplifier can be delivered with a testpoint at the output to measure the level. The 19” construction with the possibility of 4 amplifiers in one housing guarantees compact assembly in headends. In the basic version the housing is provided with a redundant power supply and double powercord.
