JQ1AP-B-12V-F

Power Relays, Over 2 Amps – JQ1AP-B-12V-F application field and working principle

The JQ1AP-B-12V-F is a power relay designed for applications that require switching loads bigger than 2 Amps. It’s suitable for demanding environments where mechanical and thermal shock resistance are critical. With a built-in fail-safe mechanism, this power relay can ensure reliable switching, reducing the possibility of breakdown, even if overload, under voltage, and temperature extremes occur.

Design & Construction

The contacts of the JQ1AP-B-12V-F are configured in the classical physical form of two, one normally open contact (NO) and one normally closed contact (NC). These contacts are placed in a secure housing, usually made of a hard plastic or potting material, providing protection against physical shock. In order to reduce contact bounce, the normally open and normally closed contacts are linked with a movable armature that has one or more arcs of contact.

Operating Principles

The principle of operation for the JQ1AP-B-12V-F power relay is as follows: when voltage is applied to the relay, an electromagnet, created by the coil, pulls the armature (or movable contact) into a position such that the normally-open contact is closed. When the voltage is removed, the electromagnetic effect becomes inactive and a reset spring returns the armature in the initial position, thus opening the normally-open contact.

The intensity of the current through the coil is selected based on the switching requirements. In case of multiple poles, the current is respectively shared between the poles in order to increase the stability of the system.

Applications

The JQ1AP-B-12V-F power relay can be used in various electronic applications, such as those involving heating, lighting or motor control. Due to its compact size and rugged construction, it’s ideal for applications in harsh industrial environments, where safety and reliability are paramount. It is also suitable for controlling multiple power circuits in series or parallel.

In addition, the JQ1AP-B-12V-F is especially designed for use in smart home automation applications, where the relay is used to switch mains voltage on and off according to various programmable instructions. It is also important to note that this power relay is compliant with some of the most important local safety regulations.

Conclusion

The JQ1AP-B-12V-F is a power relay that is perfect for all sorts of demanding environments and applications, especially those related to smart home automation. It is designed to switch high-current loads of over 2 Amps, with a built-in fail-safe mechanism and protection against mechanical and thermal shock. The relay operates according to the simple principle of voltage-activated electromagnetism, ensuring reliable switching even under extreme conditions, thus making it a perfect solution for various industrial, commercial, and residential applications.
