The Power Relay S3EB-5V is an electrical device used to reliably control an output circuit by a simple electrical signal. It is most often used to interface devices of different voltage levels. The S3EB-5V offers a reliable, two-pole contact design and is rated for use with loads up to 2 amps of AC or DC current. This Power Relay is widely used in many industries due to its superior ability to reliably switch power circuits.

Application Field

The S3EB-5V is most often used in HVAC (Heating, Ventilating, and Air Conditioning) applications. It is also frequently used in industrial equipment including motor control, automated material handling, and transfer switch controllers. Due to its superior switching capabilities, the S3EB-5V is used in many applications requiring multiple switching capabilities.

Working Principle

The S3EB-5V works with a simple two-pole contact design. The two-pole setup works by energizing a coil that is placed in between the two contacts, thereby creating an electromagnet. When the coil is energized, the electromagnet pulls the contacts closed, connecting the output circuit. The contacts then allow current to flow through the output circuit, and the load can be powered on or off depending on the polarity of the energized coil.

The contacts are normally open when the coil is not energized, and when the coil is energized the contacts close. This allows the S3EB-5V to act as a switch in circuit design, allowing the control of a power circuit. The current rating of the S3EB-5V limits the load it is used with, as the contacts would be damaged if overloaded. The maximum current rating is 2 amps for AC or DC current.

Environmental Testing

The S3EB-5V must go through many tests to ensure it performs reliably under a variety of environmental conditions. Some of the tests include hot-spot testing, vibration testing, and salt-fog testing. Hot-spot testing measures the temperature of the contact points while under load, and ensures the contacts do not overheat when the relay is used. Vibration testing ensures the functionality of the S3EB-5V under operational and environmental vibrations. Salt-fog testing simulates the corrosion that can occur from long-term exposure to moisture and salt, and ensures the reliability of the contact points.

Conclusion

The S3EB-5V Power Relay is a great choice for reliable switching needs. It is capable of handling up to 2 amps of AC or DC current, and is highly regarded in a variety of applications. Before use, the S3EB-5V must complete a number of tests to ensure it is able to properly switch its output circuit. The two-pole contact design offers superior reliability and ensures the contacts do not overheat or become corroded. The S3EB-5V is a great choice for any application requiring reliable switching of power circuits.
