Power Relays, Over 2 Amps: ALE12F12 Application Field and Working Principle

The ALE12F12 is a power relay used for electrical protection. This is a single pole relay with a current rating of up to 2 A. The ALE12F12 relay has various applications, and its principles of operation are simple.

Application

The ALE12F12 relay is used in different applications, primarily electrical protection, such as surge protection for electrical circuits. This relay can be used in both home and industrial applications to monitor the current levels and protect electrical equipment from overcurrent situations. Moreover, it can be used for fuses and short circuits, as well as for single-phase motor protection. The ALE12F12 is also suitable for use in industrial control, automation, communication, home appliances, medical and camping applications.

Working Principle

The working principle of the ALE12F12 relay is simple. The relay has a coil that is, when energized, attracted to a movable ferromagnetic component. This creates a conductive path which establishes a physical connection between the contact points. When the coil is de-energized, the movable ferromagnetic component is released, breaking the physical connection between the contacts. This continuous on/off pattern enables the ALE12F12 to act as a safety switch or disconnector. The ALE12F12 also includes an integrated diode to protect against voltage spikes. This diode limits the reverse voltage magnitude in case of an overvoltage situation, providing additional protection against overcurrent and short circuits.

Conclusion

In conclusion, the ALE12F12 is a power relay widely used for electrical protection. It can be used in a variety of applications, from home appliances to industrial control, and its working principle is simple. The ALE12F12 also includes an integrated diode for enhanced protection against overvoltage and short circuits.
