1. Technical specifi cations
1.1. COFDM-QAM CI ref. 563601
* The unit’s consumption with CAM will depend on the type of CAM being used. For preamplifi ers it is considered a standard consumption of 50mA.
The Power Supply Unit is able to powering up to seven COFDM-QAM CI modules maximum.
Is necessary to use both PSU outputs when consumption of one of them exceeds 4A (maximum current in each output).
The technical characteristics described are defi ned for a maximum ambient temperature of 45°C (113ºF). Forced ventilation must be used for higher temperatures.
