Power Relays, Over 2 Amps

JQ1A-12V Application Field and Working Principle

The JQ1A-12V is a power relay that has a load capacity of over 2 Amps. This type of relay can be used in a wide range of applications, such as in power supplies, electric motors, and other control systems. The relay is designed to open and close electrical circuits by using an electromagnetic field and energizing an electromagnet to actuate the relay switch.

The JQ1A-12V is unique in that it can be configured in a normally open or normally closed position. In a normally open position, the electromagnetic field is energized so that the spring mechanism moves the coil magnetically caused by the current flow through the coil. The current then turns on the resulting circuit. This is useful for activating systems with no power or input. The normally closed position is much like the normally open, but in the opposite direction, where the electromagnetic field is energized and the coil magnetically closes the circuit.

The relay can also be configured to act as a switch either with manual operation or with an automated system. Manual switching of the relay is achieved by using a simple switch and actuation lever which is routed to the relay’s actuator. On the other hand, automated switching can be achieved by using a PLC, timers, or sensor inputs to actuate the relay switch.

The JQ1A-12V features a number of safety features, which makes it one of the most reliable power relays available in the market. The core build of the relay includes a ground fault interrupter circuit, which is designed to immediately disconnect the power in case of a short circuit. Furthermore, the relay also includes a switch-controlled power-breaker table which is designed to detect any dangerous over-energization events.

The JQ1A-12V is also designed to withstand extreme temperatures and humidity, making it ideal for use in the harshest environments. The casing is constructed of polycarbonate which is corrosion-resistant and has the added benefit of being able to dissipate heat quickly. Additionally, the contacts are made from a manganese alloy for maximum heat resistance.

Overall, the JQ1A-12V is an excellent choice for applications where reliability and safety are essential, such as in power supplies, electric motors, and other control systems. It is also a perfect choice for applications where the environment can be extreme. The JQ1A-12V is designed to be a dependable power relay with a range of features designed to ensure maximum safety and performance.
