General
Consumption (with signal)*:
24V : 550 mA typ. (no CAM inserted; LNB power OFF)
24V : 590 mA typ. (CAM inserted; LNB power OFF)
24V : 755 mA typ. (no CAM inserted; LNB power ON)
24V : 810 mA typ. (CAM inserted; LNB power ON)
Index of protection: IP20
*The unit’s consumption with CAM will depend on the type of CAM being used. For the LNB it is considered a standard consumption of 300 mA.
The technical characteristics described are defi ned for a maximum ambient temperature of 45°C (113ºF). Forced ventilation is used for higher temperatures.
