Power Relays -- Over 2 Amps -- JQ1A-3V Application Field and Working Principle

JQ1A-3V type power relays are specially designed relays to provide powerful direct current (DC) with an operating current of over 2 Amps. This type of relay has multiple applications such as switching power supplies, LED light control systems, electrical heating control systems and AC motor control systems. This type of relay can be used in a wide range of AC and DC applications and can be easily integrated into industrial automation processes and systems.

The JQ1A-3V power relay is a dual-coil latching relay with a contact plunger mechanism. Its latching type design which is similar to its predecessors, the JQ1 and JQ2, is preferred when a switch needs to stay in a certain position during every operation. The reason is that the relay does not consume power all the time the actuating coil is energized, which improves efficiency and helps reduce power consumption.

The main components of the JQ1A-3V power relay are an actuating armature, a contact arm and contact points. When the relay’s actuating coil receives an electrical signal from a controller or timer, the armature attracts the contact arm and the contact points. This creates a closed electrical circuit, allowing current to pass from the actuating coil to the load. Once the current passes through the load, the actuating coil remains in its position until the electrical signal is interrupted or the current is removed from the circuit. The contact arm is then free to spring back into place, opening the circuit and stopping the current.

The JQ1A-3V power relay operates in temperatures ranging from -40 degrees Celsius to 85 degrees Celsius and can withstand shock and vibration up to 10G. This type of relay also features a highly efficient reed magnet, which helps to provide low contact resistance and high contact current. Additionally, it has a long service life due to its high contact pressure and low contact wear.

JQ1A-3V power relays have a wide range of applications and are highly reliable. They are used in industries such as automotive, home automation, telecommunications, medical, and industrial automation. As such, they are used in robotics, medical equipment, solar energy systems, traffic signal systems, PLC circuits, and more. The relays are suitable for use in AC and DC circuits and can operate in harsh environments.

The JQ1A-3V power relay is an ideal solution for a variety of applications. Therefore, they are one of the most widely used types of power relays in industrial automation and other applications. They provide reliable performance and are easy to integrate into existing systems. With their low power consumption, reliable operation, and long service life, JQ1A-3V power relays are an excellent choice for any application.
