The JQ1A-18V power relays, over 2 amps, provide a reliable means of controlling a circuit by opening and closing contacts from a remote location, such as a switch or a computer. The JQ1A-18V is an electro-mechanical relay designed for general purpose applications requiring switching of currents higher than 2 amperes. In its basic form, the JQ1A-18V consists of a coil and contact combination, housed in a plastic or metal enclosure. The coil is energised by a DC source and when energised the relay pulls in, and opens or closes the contacts. The contacts are rated for a certain electrical load at a given voltage, and their ability to transfer this power is monitored by an on board LED indicator.

The main application fields that the JQ1A-18V is suitable for include industrial controls, home-automation, motor-control, process-control and HVAC systems. As the contacts are able to switch up to 2 amperes, the JQ1A-18V is therefore ideal for switching a wide range of signal types such as AC, DC, DC motor, solenoid valves, heating elements, fan speeds and lighting systems.

The workings of the JQ1A-18V relay are fairly simple. When an electric current or signal is applied to the coil, it becomes magnetised and induces an electromagnetic field. This in turn causes the armature to move and cause the contacts to close or open. Once the contact is open or closed, the coil loses its magnetic ability and the armature is released, resulting in the contacts returning to its original position.

The JQ1A-18V is a versatile and reliable power relay for managing larger current switching applications, and is built to international standards for safety and performance. The JQ1A-18V includes several features to ensure the build quality is maintained, such as a dust-proof, oil-resistant and shock-resistant enclosure. Additionally, the contacts are protected from current overloads and spikes, ensuring reliability and safety.

The JQ1A-18V is also a cost-effective power relay due to its wider current switching abilities and international safety standards. As the relay includes an on board LED indication, this helps to reduce wiring costs and the risk of accidental shorts. As the JQ1A-18V is also designed to be used in electrical systems which require long-term dependability, the quality of the components ensures a long service life.

Therefore, the JQ1A-18V power relay, over 2 Amps, provides reliable power switching over a wide range of current types. With its industrial-grade safety ratings, long-term performance and cost-effectiveness, the JQ1A-18V is the perfect choice for large-scale electrical applications.
