ALZ51F18

The ALZ51F18 is a power relay, working with current over 2 Amps, that is widely used in various applications and industries due to its sophisticated electric structure and incredible contact capacity. Its coil is composed of several turns of wound copper wire encapsulated in a plastic materials and connected to a voltage source, and it has a contact structure consisting of silver or gold alloy interlocked by metallic leaf springs. As the voltage to the coil builds up, it creates a magnetic field, which in turn sets off a plunger that causes a switch contact to close or open.

Such high current power relay is mainly used to provide isolation between the circuit’s power source and the load, and as an indicator of circuit operation. The general applications of ALZ51F18 power relay include electronic equipment control, various actuators control, and simple machine control. With a maximum contact capacity up to 10A/600VAC/300VDC, ALZ51F18 offers a wide range of working currents and voltages for different coming from different power sources.

In terms of working principle, ALZ51F18 is designed to activates relay contact against the incoming current. As the voltage to the coil builds up, magnetic field is created, which in turn sets off a plunger that causes a switch contact to close. This contact then maintains a closed or open circuit until the input current is reduced and then falls below a specified value. When the input current falls below this value, the contact will automatically switch open and the relay will deactivate. This process is also known as “holding current”.

In order to ensure a durable and reliable operation and long life-time, ALZ51F18 features a dust-resistant contact and frame design and a heavy-duty coil that is resistant to environmental factors such as ambient humidity and temperature change. It also employs advanced suppression techniques that prevent high transient surge voltages from affecting the relay’s electrical performance.

Overall, ALZ51F18 is a reliable high current power relay with tremendous contact capacity and numerous versatility and applications. It can be used to provide isolation between the circuit’s power source and the load, and as an indicator of circuit operation. The dust-resistant contact and frame design and a heavy-duty coil make it suitable for various working conditions and fields of use.
