REMARKS
• The power supply can power up to a maximum of 7 modules with CAM, and being active only 2 LNB feeds of the assembly of seven multiplexer.
• When a CAM is inserted, it is assumed that the multiplexer’ consumption increases about an average of 70 mA (since CAM consumptions in the market

can vary between 20 & 100 mA). Each LNB feed activated increases the multiplexer’ consumption about 250 mA (also depending on the LNB model).

• The two PSU power outputs must be used in order to balance their consumptions in a chassis, therefore whenever the demand of power exceeds 4A

(max. current for each output), it is necessary to distribute it between the two powering outputs of the PSU (for example: 4+3 modules; 3+4 modules).
