Embodiment Construction

[0018] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0019] The invention provides an electromagnetic powder tensioner control circuit, including a 220V / 0-24V adjustable power supply 1 and an electromagnetic powder tensioner 2, the electromagnetic powder tensioner 2 and the adjustable power supply 1 are connected in series to form a loop through wires, and the loop is connected in series There are multiple diodes 3 so that there is no direct current output when the voltage in the loop is less than 2.1V.

[0020] The inventor found through investigation and research that the resistance of the electromagnetic powder tensioner 2 is small, and when the adjustable power supply 1 is at 0-1V, the electromagnetic powder t...

Abstract

The invention discloses an electromagnetic powder tensioner control circuit. The control circuit comprises a 220V/0-24V adjustable power supply (1) and an electromagnetic powder tensioner (2), wherein the electromagnetic powder tensioner (2) is connected with the adjustable power supply (1) in series through a wire to form a loop; and the loop is connected with multiple diodes (3) in series to enable that when the voltage in the loop is less than 2.1V, no direct current is output. According to the electromagnetic powder tensioner control circuit, the misoperation of the electromagnetic powder tensioner at a low voltage can be avoided.

Description

technical field [0001] The invention relates to a control circuit, in particular to a control circuit of an electromagnetic powder tensioner. Background technique [0002] During the use of the electromagnetic powder tensioner, its power supply is generally a DC power supply. In the actual production process, AC power is often converted into DC power by a converter for reuse. For example, a 220V / 0-24V adjustable power supply converts 220V AC into 0-24V DC. [0003] When the electromagnetic powder tensioner is used in series with the adjustable power supply, it often cannot be displayed under low voltage conditions, which leads to user misoperation, which not only greatly hinders the use of the electromagnetic powder tensioner. Contents of the invention [0004] The object of the present invention is to provide a control circuit of an electromagnetic powder tensioner, which can avoid its misoperation under low voltage. [0005] In order to achieve the above object, the pr...
