The EBUS power source from the coupler and Flex-6 Nano at 40 degrees celcius are:

P600 : 2700 mA maximum.

P366 : 2860 mA maximum.

The maximum number of modules is defined by the power on the EBUS and the propagation times over the EBUS data terminals. The absolute maximum is 16 modules dues to propagation delays. The actual maximum determined by power consumption can be calculated from these numbers:

P371, P372, P376, P377 : 150 mA per module

P375 : 330 mA per module

P379 : 220 mA per module

P378 : depending on analogue output load...

                       Worst case with 2K Ohm load on each Analog Output 650 mA

                       Case with 10K Ohm load on each Analog Output 440 mA

                       Case with no load 330 mA

Handy table of power multipliers.  Must add up to 16 or less.
