Abstract

The invention provides an intelligent power switch capable of adjusting the power-off time. The power switch comprises a power supply circuit, a time adjustable timer circuit and a power switch driving circuit connected successively, wherein the power supply circuit carries out overcurrent, anti-reversal-connection, transient inhibition and filtering on power signals, and then supplies power to the time adjustable timer circuit and the power switch driving circuit; and the power switch driving circuit switches off the power supply according to the ON / OFF state of the power switch and the output state of the timer circuit. Compared with the prior art, the intelligent power switch has the advantages that (1) special using requirements are met, and the power switch is especially suitable for intelligent device or instrument which needs rapid and delayed power off; and (2) the requirement of intelligent control is met, the power off time can be adjustable via parameters of circuit components.

Description

technical field [0001] The invention belongs to the technical field of intelligent industrial control, in particular to an intelligent power switch with adjustable off time. Background technique [0002] Traditional power switches generally include: manual operation switch, relay switch, contactor switch, etc. These types of switches have been widely used because of their simple operation and easy maintenance. However, these types of switches have shown certain shortcomings in actual use, such as high cost, low reliability, low intelligence, and potential safety hazards, and cannot meet some special applications. power supply for special equipment needs. Contents of the invention [0003] In view of this, the present invention aims to propose an intelligent power switch with adjustable off time, so as to realize the function of delaying power off. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005...
