More Information
Summary:The present invention relates to a power supply module and a power supply unit using such a power supply module. A power supply module includes a plurality of power supply modules. One of the power supply units is designated as a master power supply unit. Other power supply units are handled as expansion power supply units. The power supply modules can be connected in parallel on a DIN rail so that the master power supply unit may supply an external AC voltage to the expansion power supply units. When a desired power supply capacity exceeds a power supply capacity of the master power supply unit, an expansion power supply unit is connected in parallel with the master power supply unit in order to increase the power supply capacity.
