Automotive relays refer to equipment for short-circuiting or disconnecting power circuits. They are widely used in the automotive industry, especially in fuel blocking or charging control systems. CB1-WM-24V is an example of automotive relays. It is mainly used in the application field of AC/DC conversion or DC/DC conversion, as well as in fuel blocking or charging control systems. This article introduces the working principle and application fields of the CB1-WM-24V.
The CB1-WM-24V has an internal electromagnet for driving the contacts, and a transformer that monitors the state of the contacts. When the circuit is closed, the current from the primary winding of the transformer is interrupted, which causes the current to be directed to the secondary winding. The current generated in the secondary winding activates the magnetic coils and causes the contacts to close. When the contact is opened, the primary winding supplies the current, thus opening the contact.
The main application field of the CB1-WM-24V is AC/DC and DC/DC conversion. In the AC/DC conversion process, the contact is open, allowing the generator to flow into the input of the transformer. When the contacts are closed, the output of the transformer is fed to the load, thus converting the alternating current to direct current. In the DC/DC conversion process, the contact is open, allowing the generator to flow into the input of the DC/DC converter. When the contacts are closed, the output of the converter is fed to the load, thus changing the voltage of the direct current.
The CB1-WM-24V is also widely used in fuel blocking or charging control systems. In the fuel blocking system, the contact is open, allowing the fuel tank to be filled. When the contacts are closed, the fuel level is reduced and the fuel is blocked. In the charging control system, the contact is open, allowing the load to be charged. When the contacts are closed, the charging is stopped and the load is discharged.
In summary, the CB1-WM-24V is an automotive relay mainly used in AC/DC and DC/DC conversion, as well as in fuel blocking or charging control systems. It utilizes an internal electromagnet for driving the contacts and a transformer that monitors the state of the contacts. By using the CB1-WM-24V, many processes in the automotive industry can be automated, bringing convenience and efficiency to the users.
