JK1A-18V

The JK1A-18V is a sensitive general purpose power relay with a pick-up voltage of 1.4 volts and a drop-out voltage of 0.18 volts. The relay has an over 2 amp capacity, making it suitable for a variety of applications. This article discusses the application and working principle of the JK1A-18V power relay.

Application

The JK1A-18V is used in a variety of applications, including:

• Interfacing DC and AC currents
• Automatic switching systems
• Circuit breakers
• Electronic control circuits
• Telecommunications equipment
• Fire alarm systems
• Appliance control circuits

Working Principle

The JK1A-18V power relay operates on the principles of electromagnetic induction. An input signal, typically in the form of an alternating current (AC) or direct current (DC) voltage, is applied to the input of the relay. This input signal causes the induction of a magnetic field in the relay\'s armature. The magnetic field interacts with the lever mechanism of the relay, causing it to move and close the contacts. This closing of the contacts creates a closed circuit, allowing current to flow through it. The current flow can then be used to operate other circuits or devices.

The JK1A-18V is designed with a low pick-up voltage and low drop-out voltage, making it suitable for a wide range of applications where minimum power consumption is required. The over 2 amp capacity of the relay makes it suitable for larger loads as well.

Conclusion

The JK1A-18V is a sensitive general purpose power relay with a pick-up voltage of 1.4 volts and a drop-out voltage of 0.18 volts, and an over 2 amp capacity. It is used in a variety of applications, including interfacing DC and AC currents, automatic switching systems, circuit breakers, electronic control circuits, telecommunications equipment, fire alarm systems, and appliance control circuits. The relay operates on the principles of electromagnetic induction, and its low pick-up and drop-out voltages make it suitable for a wide range of applications with minimal power consumption.
