Abstract
The utility model relates to a power supply system, in particular to a household safe energy-saving power supply system which comprises a power supply changeover end and a power supply output end. The power supply changeover end and the power supply output end are connected by a power supply line. The power supply changeover end converts commercial power into a low-voltage DC power supply and outputs the low-voltage DC power supply to the power supply output end. The household safe power supply system utilizes the power supply changeover end to convert the commercial power into the low-voltage DC power supply and outputs the low-voltage DC power supply to the power supply output end, and the power supply output end can be used after switching on low-voltage DC load; as the voltage of the low-voltage DC power supply is low, the current in the line cannot injury a human body; when the line is out of function, a user can be reassured to carry out examination and reparation; in addition, the low-voltage DC power supply cannot easily cause electric sparks and the heating value of the line is low, so that fire disasters are avoided; moreover, as the load switched into the power supply system all runs in the low-voltage DC state, any injury to the human body cannot be caused even if the load causes electric leakage.
