[QUOTE="Terryl, post: 1065341, member: 369937"] Most work internally at +5 to +6 volts, with some in the +3 volt range on the IC's, it's the transponder selection voltage at +13 or +18 volts that you need to worry about, if those drop below the threshold (usually a half to a volt below) your transponders won't switch right. Here stateside we sometimes use an OEM LNB that has 3 heads and is a DC current hog at 750 mA, when used with a standard FTA receiver the DC current supplied is only 500 mA. so you can see the problems we get. The OEM receiver that is used with this type of LNB has a 1.2 amp output, and when it detects this type of LNB turns the DC voltage supply to the LNB up to 20 volts as it does not use the voltage switching for the transponders.
