SFY5-DC18V

The SFY5-DC18V Power Relay is a versatile device commonly used to switch high-voltage electrical current from one device to another, making it one of the most popular over 2 Amps relays on the market. It is capable of handling up to 150 Amps of power and operating at a maximum of 24V DC. The SFY5-DC18V is widely used in many applications where reliable control of electrical loads is required. The following article will discuss the application fields and working principle of the SFY5-DC18V.

Applications

The SFY5-DC18V Power Relay has a broad range of applications due to its size and capability. It is often used in automotive, household, electronic equipment, and industrial applications, such as controlling electric motors, remote control devices, and other high-current electronic devices. It also finds use in refuse collection vehicles, emergency lighting, and power supplies. Its high current rating makes it suitable for use in applications where reliability and safety are a priority, such as medical instruments, power supply testing, and communications systems.

Working Principle

The SFY5-DC18V Power Relay is an electrical switch that is triggered automatically when an electric current passes through its contacts. This type of relay has a set of contacts that close when electric current is passed through the contacts. When the electric current passes through the contacts, it causes a coil inside the relay to become energized. This energized coil magnetically pulls the relay armature onto a set of contacts, initiating the relay\'s action.

The SFY5-DC18V Power Relay is equipped with a ‘self-reset’ feature, which ensures that the relay resets itself automatically each time it is triggered. This feature improves reliability and longevity by enabling the relay to automatically reset itself when the electric current is removed, preventing it from overloading and burning out. In addition, the current ratings mean that this relay can control a variety of loads without the need for a larger relay.

Conclusion

The SFY5-DC18V Power Relay is a versatile and reliable relay that is frequently used for high-current applications. Its high current ratings and self-reset functionality make it an ideal choice for automotive, industrial, and electronic applications. The ease of installation and reliable operation make it a popular choice for many applications. In summary, with its wide range of applications and reliable operation, the SFY5-DC18V Power Relay is an ideal choice for many applications requiring reliable control of loads.
