Abstract
A universal power supply system allows each board mounted DC power module or each AC/DC power supply device therein having identical dimensions and appearance to further have a specification setting circuit. When the board mounted DC power module or the AC/DC power supply device is plugged in a backboard module, the specification setting terminal outputs a specification identification signal to a monitoring circuit of the backboard module. As built in with a specification mapping table, the monitoring circuit can compare the specification identification signal to find a model number corresponding to the signal, and automatically sets a critical current value or critical power value of each board mounted DC power module for over-current protection or over-power protection. Accordingly, the universal power supply system can be adapted to different board mounted DC power modules or AC/DC power supply devices without redesigning the backboard module.
