Problems solved by technology

[0002] The traditional micro-disconnect switch will only disconnect one of the wires for the control of the live wire and the neutral wire. Such a safety hazard is that once the live wire and the neutral wire are reversed, there will be a phenomenon that the live wire is not disconnected.

Abstract

The invention discloses a dual-disconnection switch controller. The dual-disconnection switch controller comprises a shell, wherein a circuit board is fixed in the shell; the circuit board is provided with a control circuit; the control circuit comprises an AC-DC switching circuit, a DC-DC switching circuit, an MCU and a relay control circuit; the AC-DC switching circuit is used for supplying direct current to the DC-DC switching circuit and the relay control circuit; the DC-DC switching circuit is used for supplying power to the MCU; and the relay control circuit is used for controlling the on / off of a neutral wire and a live wire, and is controlled by the MCU. According to the dual-disconnection switch controller, the relay control circuit is used for controlling the on / off of the neutral wire and the live wire, so that the safety level of the product is improved; and the neutral wire and the live wire are subjected to dual-disconnection protection by the dual-path control.

Description

technical field [0001] The present invention relates to a double disconnect switch controller. Background technique [0002] The traditional micro-disconnect switch only disconnects one of the lines for the control of the live line and the neutral line. Such a safety hazard is that once the live line and the neutral line are reversed, there is a phenomenon that the live line is not disconnected. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to overcome the above-mentioned disadvantages, aiming to provide a double disconnect switch controller. [0005] (2) Technical solution [0006] In order to achieve the above object, the double disconnection switch controller of the present invention includes a housing, a circuit board is fixed inside the housing, and the circuit board is provided with a control circuit; the control circuit includes an AC-DC conversion circuit, a DC- DC conversion circuit, MCU a...
