Power Relays, Over 2 Amps

Power relays are electrical switches used to handle large amounts of electrical current and torque, often in the range of 2 to 6 amps. They are used to switch high-voltage circuits and to provide control over large motors, such as those found in automotive and other vehicles. The BR231-450C1-28V is a specific type of power relay produced by Tyco Electronics. It is a high-current, DPDT (double pole double throw) relay designed to provide power control for up to 28 volts and 450 amps.

Application Field

The BR231-450C1-28V is designed for use in highly automated applications, such as those found in the automotive and aerospace industries. It can also be used in the manufacturing of electric vehicles, robots, and other high-tech devices. The BR231-450C1-28V can also be used in consumer electronics, such as digital cameras, phones, and computers. It can be found in many other applications as well.

Design Features

The BR231-450C1-28V operates with a 0.2 to 0.6 second response time and weighs 64g. It has a current rating of 450A at 28V and features a micro switch, two additional auxiliary contacts, and an LED indicator. It is rated for operating temperatures ranging from -30 to 85°C and is resistant to shock and vibrations.

Working Principle

The BR231-450C1-28V power relay is designed to regulate the flow of electrical current. It is controlled by a micro switch that can be turned on or off, allowing the relay to control a larger amount of current than a typical switch. When the micro switch is turned on, it triggers the release of a latch, allowing the power to flow through the relay. When the switch is turned off, the latch is reset and the power is cut off. The two auxiliary contacts allow for additional control of the current, such as for monitoring voltage levels or temperature. The BR231-450C1-28V also has an LED indicator that is used to show the status of the relay.

Advantages

The BR231-450C1-28V power relay offers several advantages over other relays, including increased current handling, improved control accuracy, and a compact design. With its 0.2 to 0.6 second response time, it is well-suited for applications requiring precise control, such as those found in aerospace and automotive industries. Additionally, its micro switch features high contact reliability and minimal current leakage, making it suitable for high-power applications. Its robust design also allows for operation in extreme environments, such as high vibration or shock conditions.

Conclusion

The BR231-450C1-28V power relay is a reliable, high-current device designed for use in a variety of applications. Its design features make it suitable for high-voltage, high-temperature, and high-power operations. Its micro switch and auxiliary contacts provide precise control and monitoring capabilities, making it a reliable option for many industries.
