Power Relays, Over 2 Amps

The ALE15B18 is a device from the family of Power Relays. It is designed to work with loads that exceed the typical 2 amp ratings that many other relays can handle. It has a power rating of 18A and is unidirectional, quick-breaking, and operates at a voltage between 6-15VDC. These features make it ideal for applications such as LED lighting and automotive systems.The basic function of this relay is to act as an intermediate switch between two sources. It is capable of controlling the flow of an electric current, from one source to another, depending on the input signal given to the coil. When the input signal is not being applied, the current flow is blocked, but as soon as the signal is sent, the relay will open the circuit and the current can flow. Since these relays are non-polarized, they can handle AC current as well. The ALE15B18 is built with a very robust frame and protection in order to withstand severe environmental conditions. It can safely operate between -40 to 85°C and has a maximum voltage of 40VDC. This ensures that the relay is suitable for a variety of applications and provides reliable power management. Additionally, it is designed to reduce the risk of short-circuiting, as it is built with an over-voltage and over-current protection circuit.In terms of a connection system, the ALE15B18 has several options. It can be connected via a removable terminal block or it can be wired to a printed circuit board for a more permanent solution. It can be used in multiple operating modes including pulse, latching, or momentary and can be controlled from either a DC or AC supply. This makes the ALE15B18 extremely versatile and suitable for any type of application.The ALE15B18 works by allowing current to pass through its switching contacts when it is connected to a power source and a load. When a current is applied to the coil, a magnetic field is formed, and this field is used to pull the armature from its original resting position. This allows the contacts to open, which breaks the circuit and prevents the current from passing through. When the current is shut off, the armature is released and the contacts close, thus allowing the flow of electric current.Overall, the ALE15B18 device is a robust and reliable piece of electronics with a wide range of applications. It is capable of handling up to 18Amps of power and operating from 6-15VDC. It is also designed to handle a wide range of temperatures, is non-polarized so it can handle AC as well as DC current, and is even designed to reduce the risk of short-circuiting. It can be connected in multiple ways and used in a variety of operating modes, making it highly versatile.
