Power Relays, Over 2 Amps: ALZ12F12W Application Field and Working Principle

A power relay is a type of electrical relay that specializes in switching high-power electrical circuits, meaning the relay can control a circuit which handles as much as several hundred volts and several amps. The ALZ12F12W relay, in particular, is an Alternating Relay with an operating voltage of 12 volts and a contact current rating of 12 amps when used on DC systems (for AC systems, its rated current is 6 amps).

Application Field

The ALZ12F12W relay is a type of single pole, double throw (SPDT) relay which is commonly used in automotive, marine, or even home applications. Automotive and marine applications often require the ALZ12F12W because of its high-power rating. It can be used to control the actions of something as large and powerful as an electrical fuel pump, for example. Many designers also like to use the ALZ12F12W in home applications due to its robust and reliable design. It is often used in alarm and control systems, and even in craft projects. Its high power rating makes it suitable for handling large devices such as electric saws, drill presses, and even refrigerators.

Working Principle

The ALZ12F12W relay works simply as an electrical switch. An electrical signal is sent to the relay from a control circuit, and then the relay switches on a circuit which is connected to the relay. The ALZ12F12W relay uses an electromagnet to control its contacts, and when the input signal is sent to the relay, the current flowing through the electromagnet increases and causes the armature to move. This movement of the armature causes the movable contacts on the relay to move from one fixed contact to the other.

Structure and Coil Voltage

The ALZ12F12W relay is a standard SPDT relay and consists of two coils, a contact armature, and two fixed contacts. The relay is designed to be energized by 1-5 dc volts, though is can also be energized by 1-252Vac (50/60Hz). There is also a two-digit code which is stamped on the relay which indicates the dry coil voltage of the relay, which can be as low as 3V to as high as 400V.

Advantages

The ALZ12F12W relay has several advantages over other types of power relays. First, it has an extremely high power rating, which makes it ideal for handling high power applications. Secondly, its design is robust and reliable, so it is unlikely to fail even when used in harsh or extreme conditions. Finally, it is extremely easy to use and can be connected in many different ways with relative ease.

Conclusion

The ALZ12F12W is a reliable and powerful power relay which is suitable for use in automotive, marine, and home applications. Its high power rating makes it appropriate for handling high-powered devices such as fuel pumps, saws, and drill presses. In addition, its reliable design ensures that it is unlikely to fail even when used in harsh or extreme conditions. Finally, its easy installation and setup makes it a popular choice among many designers.
