Power relays are electromechanical devices used to control and protect electrical circuits. ALZ21B18 power relays offer high levels of stability and reliability as they are designed for infrared, regular and high temperature applications. ALZ21B18 power relays are designed with a thermal overload protection, high voltage (up to 1000 VDC) and over 2 amps, this makes them suitable for use in a wide range of applications.

The ALZ21B18 has a very compact package size but highly efficient design. Internally the relay contains a magnetic or reed switch and an electronic coil or relay. When electricity is directed to the relay, the coil surrounding the switch is energized and produces a magnetic force that closes the switch. When power to the coil is cut off, the switch will open.

The ALZ21B18 relays are highly reliable and ideal for applications such as industrial control, medical equipment, automotive, consumer electronics and so on. They are also well suited for harsh environment applications such as high temperature, humidity, or even shock and vibration environments.

The ALZ21B18 is designed to be used in various configurations, so it can be used as a single and double pole device. It also includes a variety of features such as: high temperature rating, surge protection, snubber circuit, EMC protection, and more. The ALZ21B18 also has a built-in safety feature which will prevent electrical overcurrents or short circuits.

The ALZ21B18 is generally used in applications in which high current is needed for prolonged periods and where excellent reliability is required. It is ideal for applications such as industrial machinery, transformers, motors, and other electrical devices which depend on continuous and reliable electrical power operation.

The ALZ21B18 has a wide range of working principles, including: latching, cycling, and static operation. In the latching and cycling mode, the relay is capable of turning on or off for a predetermined amount of time. This is useful for controlling the speed or torque of the motor and protecting against overloads. The static mode is typically used to maintain a specific state of the output.

The ALZ21B18 is also highly resistant to electromagnetic interference which makes it the ideal choice for applications that require a high degree of EMI protection. In addition, the ALZ21B18 is also designed to be resistant to shock and vibration, enabling a high level of reliability for applications where these factors are present.

The ALZ21B18 power relays offer a wide range of applications and features, making them highly suitable for use in a variety of industrial and consumer applications. With its highly reliable and stable design, it is the perfect choice for reliable and efficient performance even in the toughest of environments.
