Dimensioning the power supply

When the total consumption of all modules powered by one power supply is greater than the capacity of the power supply, you need several power supplies that can be connected in parallel or you can arrange the power supplies in segments.

Module Max consumption
BM-AG 720 mA
BM-GW 720 mA
BM-MC 280 mA
BM-LC 120 mA
BM-SS 85 mA
BM-TH 20 mA
Module Max supply
BM-PS 3.80 A
