SF4D-DC5V

Introduction

SF4D-DC5V are versatile safety contactors designed for switching low-voltage power circuits. These safety contactors can be used for a variety of applications, including motor control, switching, and over 2 Amps. This type of DC power relay has a compact design and unique features, making them well suited for low power applications.

Application Fields

The SF4D-DC5V power relay is well suited for high current switching and control applications. It can be used for controlling motors, over 2 Amps circuits, and for other applications that require a high-power output. The contactors are designed with a 3-degree switching angle, allowing for a very user-friendly operation. It is designed to operate in temperatures ranging from -40℃to 70℃, making it suitable for both indoor and outdoor applications. It also has a fast response time, allowing for quick and precise operation.

Working Principle

The SF4D-DC5V power relay works with a 3-pole contactor composed of an anode, cathode, and common. When a small electric current is energized, the contactor closes its contacts and thus switches the power circuit. When this electric current decreases, the contactor opens its contacts and switches off the power circuit. This ensures that the power current in the power circuit is always in the same direction.

Moreover, the SF4D-DC5V power relay is designed with a 1A fuse protection. This prevents overvoltage and overloads from damaging the contactors and other components in the power circuit. Additionally, the contactor is designed with a built-in indicator LEDs indicating the presence of power in the system. These LEDs can be seen from the outside, which helps in easily detecting any problem or faults in the system.

Conclusion

Overall, the SF4D-DC5V power relay is a reliable and robust power switch. It is suitable for low-voltage power applications requiring quick and precise operation. Its versatile design and features make it an ideal choice for a wide range of applications. It is a great option for installations that require reliable and secure power control and switching.
