Power relays over 2 amps are vital components of any electrical system designed to switch high current. The APF30318 relay is one of the most reliable and versatile of these power relays, regardless of the current limit, and can be used in a wide range of applications. In the following sections, we will discuss various aspects of the APF30318, including its application field and working principle.

Application Field of the APF30318 Relay

The APF30318 is a panel mount, DIN rail, and PCB mountable relay. This versatile device has been designed for use in a wide range of applications, including factory automation, robotics, HVAC systems, and telecommunications. It is capable of switching up to 30A of current at a rated voltage of 277VAC or 24VDC.

The APF30318 is also suitable for use in industrial motor control systems. It is capable of switching up to 10HP of single-phase motor load and is equipped with an adjustable timer that can be used for controlling the speed of motors. This makes it ideal for applications in areas such as food processing, material handling, and material cutting.

Working Principle of the APF30318 Relay

The APF30318 relay is based on the principle of an electromagnetic force. This force is generated by the movement of an electromagnet activated by an external electrical current. This electric current is used to move a pivot arm, which in turn moves the contacts of the relay. This causes them to close or open, depending on the electrical current and the direction of the magnetic field.

The operating temperature range of the APF30318 relay is 0°C to +85°C. The device is rated for a maximum of 5 million operations. It is also capable of continuous duty at full load for up to 1 hour at a time.

The APF30318 is equipped with a mechanical "bounce", or locking actuator, that prevents premature closure of the contacts. This ensures that the contacts of the relay can be opened and closed without interruption. Additionally, the APF30318 is designed to operate with minimal heat dissipation, providing an excellent cooling performance for the system.

Conclusion

The APF30318 is a versatile and reliable power relay suitable for a wide range of applications. Its application field covers factory automation, robotics, HVAC systems, telecommunication, and motor control. It is based on the principles of electromagnetism and equipped with a bounce actuator to prevent premature contact closure. Its operating temperature range is 0°C to +85°C and it is capable of 5 million operations. With its excellent cooling performance and long operating life, the APF30318 can be trusted to handle high current loads with ease.
