Abstract
The present invention discloses a current-limiting protection circuit for a power supply, which applies to a power supply that has a maximum power-limiting function, wherein the user will be alarmed by a time-delay alarm circuit of the current-limiting protection circuit when the power used by the loads is in a heavy-load state or a full-load state, and within the delay time preset in the time-delay alarm circuit, the user can adjust the power-limiting value according to the power needed by the loads. Thus, via the current-limiting protection circuit for the power supply of the present invention, the objective of the best power selection and protection of the power supply is achieved.
