IF Signal/ Reference/ (DC)- 150W AC/DC PSU * The features of 150W AC/DC Power Supply Unit (PSU) is to provide thestable +48V DC power to operate Ku-band 8W BUCs, even if inner power
supply of the modem is not capable enough to operate these BUCs.
* The AC/DC box, which is having enough power supply of 150W as wellas having the bias-tee which enable to pass 10MHz reference signal andL-band IF signal from the modem, is operated by AC Power and enable
to operate these BUCs.
* In addition, the aluminum housing with corrosion-proof treatment on
the surface is employed with the box to use perfectly as the indoor unit.
