Power relays are electrical switches that are used in a wide range of electronic applications. The purpose of a power relay is to make or break an electrical connection, allowing electricity to flow from one component or circuit to another. They are particularly useful for controlling large and complex circuits because of their ability to handle large current loadings. One such relay is the ALZ11B12 Power Relay, which is a reliable, robust and cost-effective device ideal for industrial and commercial system. This article will discuss the application field and working principle of ALZ11B12 Power Relay.

Applications

The ALZ11B12 Power Relay is a power relay designed for applications requiring high reliability and/or short circuit protection. It can be used in a variety of industrial and commercial systems, including motor control, power factor correction, over-voltage protection, and load switching. Additionally, it can be used as a current limiter, eliminating the need for large, expensive power resistors. Its small size and ability to handle high current make it an ideal solution for energy saving applications. The ALZ11B12 is rated for up to 2A at 250VAC, and features a device capacitance of 0.3 picofarads, making it suitable for use in high speed switching applications.

Working Principle

The ALZ11B12 Power Relay operates by using an electrically driven coil to drive the mechanical armature. When a current is applied to the relay coil, the armature is attracted to and rotates around a center pivot point. This changes the contacts of the relay from an open position, where the contacts are disconnected, to a closed position, where the contacts are engaged and electricity can flow between them. When the current is removed from the coil, the armature releases the contacts, which reverting back to the open position and breaking the circuit.

The ALZ11B12 Power Relay also features a double-make-or-break load contact. This means that when the coil is energized, the upper and lower contacts open and close at the same time, providing a stable single-throw connection. Additionally, the ALZ11B12 features a unique over-load protection system, which prevents current overloads from damaging the contacts or causing an unexpected contact closure. When an overload occurs, the overload protection system interrupts the current flow before it can cause any damage.

Conclusion

The ALZ11B12 Power Relay is a reliable, robust and cost-effective device that can handle up to 2A at 250VAC. It is suitable for motor control, power factor correction, over-voltage protection, and load switching applications, as well as high speed switching applications. It is also equipped with a unique over-load protection system, which eliminates the need for expensive power resistors. With its simple operation and over-load protection system, the ALZ11B12 Power Relay is ideal for a variety of industrial and commercial systems.
