The 411BAM is designed to act as a central component of a small E-Plex system. It can measure the voltage and current of two separate battery banks, up to 100A. It provides 3 outputs, auctioneered from the highest voltage supply and also provides 2 inputs.
Channels 1, 2, and 3 do not measure current accurately. Therefore, these values are used to give an indication of whether or not current is being drawn, rather than exactly how much is being drawn.
