LOW COST POWER SUPPLY DEVICE TO A PLURALITY OF ELECTRONIC MODULES INSTALLED IN A COMPARTMENT

摘要

In order to supply direct current to a plurality of consumer electronic modules (2 to 4), from an interfered direct voltage, with a wide range of voltage regulation, the power supply device comprises a primary supply module (5) including means for pre-adjusting voltage, for raising or lowering the direct voltage, to supply the modules (2 to 4) with a pre-adjusted voltage with a low range of voltage regulation, and in each module, converting means (6) supplying voltages adapted to the needs of the module.
