What Does the Analog and Digital Power Requirement for SCC Modules Mean? Hardware: SCC>>Carriers>>SC-2345
Problem: The specifications for the SCC Signal Conditioning modules give a power requirement specification for Analog and Digital. What does this mean and how are these values used to calculate the total power required per carrier? Solution: There are two primary voltage sources which power the SCC modules: +5V DC and +/- 15V DC. The +5V source is what is called Digital in the specifications and the +/- 15V source is what is called Analog. Since the SCC module will be drawing from both the +/- 15V source and the +5V source at the same time, the total power consumption is additive. These voltage sources are used together to operate the SCC module and therefore must be added when attempting to calculate the total power required per carrier. The SCC Power Requirements and Solutions appendix of the SC-2345 User Manual provides formulas and a table of power requirements per SCC module which may be used together to determine the analog power requirement per module, the digital power requirement per module, and the total analog, digital, and combined power required per carrier. After the combined power required per carrier is calculated, you should use this data to choose the appropriate SCC-PWR module which supplies a sufficient amount of power for your chosen SCC modules.
