Power Relays, Over 2 Amps: ALZ11B24W Application field and Working PrincipleThe ALZ11B24W is a voltage-sensitive, open-frame power relay engineered specifically for switching medium voltage applications. Developed by Alps Electric Co., Ltd., this power relay has a low current rating of 2 to 6A and is designed for use in applications requiring high switching currents and greater than 2A.In terms of its application field, the ALZ11B24W is typically used in security systems, lighting and other home appliances such as refrigerators and washing machines that require a reliable and robust switching solution to manage their high voltage needs. In particular, the ALZ11B24W relay can be used to switch high voltage motor, transformer, and capacitor connections in a wide range of electrical and electronic circuits.The ALZ11B24W relay works on the principle that, when a current is supplied to the coil, the interrupter arm should move and close the contacts. The presence of the current causes the contacts to open or close as required, which in turn allows the circuit to be powered up or shut down as necessary. The current supplied to the coil is usually set to a very low value, typically 0.2 to 0.8A, to enable a reliable and trouble-free switching mechanism.In terms of construction, the ALZ11B24W is made up of three parts—a coil, a swivel arm, and contacts—all encased within an open-frame design. The two contacts are connected to the coil via two wires, with the swivel arm making or breaking the connection between the two contacts when the current passes through the coil. The coil is also connected to the contact which provides a larger area for switching current through the contact.For efficient and reliable operation, the ALZ11B24W relay employs a typically direct-driven type of structure. This type of design uses one or multiple coils and an arm, which is often referred to as a rotor, to create the force necessary for switching. When the contact is closed, the current passing through the coil creates a magnetic field, which attracts and pulls the arm, closing the contact. When the coils are energized in the opposite direction, the arm is repelled and the contact is opened.The ALZ11B24W does not require any auxiliary elements such as additional contactors or timers for its operation. It is capable of switching high current loads and offers an advantage of being able to maintain an open contact state even in the absence of current. Furthermore, the ALZ11B24W has a low power consumption rating, making it suitable for a wide range of applications.Overall, the ALZ11B24W has proven to be an efficient and reliable switching solution for high voltage applications such as security systems, lighting, and home appliances like refrigerators and washing machines. It provides a cost-effective and efficient design, reducing the need for complex relaying systems. This open-frame design provides high reliability, and its low switching current ensures a trouble-free operation. The ALZ11B24W delivers unparalleled performance when it comes to high voltage applications and is capable of switching high current and offering a low power consumption rating.
