Power Relays, Over 2 Amps

The ALZ52F12TW is a kind of power relay with a rated operating current above 2 amperes and is suitable for high power switching applications. It can also be used for a variety of safety-critical applications, such as motor control, transformer protection, and alarm systems. It is designed with a large contact gap and high-insulation construction, making it able to resist static and dynamic loads.

Components

The ALZ52F12TW is composed mainly of a relay coil, a housing, a base, a metal contact(s), dust caps, and a connecting terminal(s). The body is die-cast aluminum, and the contact is made of silver-plated copper. The metal parts are corrosion-resistant, and the coil is protected from dust and dirt by a soft-rubber sealing strip.

specifications

The ALZ52F12TW has the following specifications: rated operating current of 8.2A; rated operating voltage of 250V; VDC contact rating is 6A; VAC contact rating is 8.2A; switching frequency of 0.5Hz; temperature rise 35K; dielectric strength of 3,000V between open contacts; surge current withstand capability of 8kA; and maximum temperature rating of 104°C.

Characteristics

The ALZ52F12TW has superior durability and reliability for its type, offering more than 10,000 mechanical cycles at full load and more than 1 million electrical cycles. The contact gap is also larger than most commercial relays. It also has good insulation performance, with a minimum insulation resistance of 1,000 mΩ at 500V and a dielectric strength of 3,000 VAC between open contacts for 1 minute.

Working Principle

The ALZ52F12TW is designed to activate or deactivate electrical circuits by the use of magnetism. It contains a metal contact(s) and an energizing coil. When a current passes through the coil, it creates a magnetic field that attracts the metal contact(s). This causes the contact(s) to close or open, thus activating or deactivating the electric circuit.

Application Field

The ALZ52F12TW finds a wide range of applications in motor control, transformer protection, alarm systems, and safety-critical applications. It is also used in telecommunication equipment, automatic control systems, medical equipment, and heating, ventilation, and air conditioning (HVAC) systems. It has been used in many products such as lighting systems, gaming machines, and other appliances.
