Power Relays, Over 2 Amps – PJR220A Application Field and Working Principle

The PJR220A is a power relay designed for uses that require high current arcs of 2 amps or more. This can be used in the automotive, industrial, and home security industries.

The PJR220A comes with a wide range of features to ensure excellent performance. It has a nominal voltage rating up to 24V AC/DC, with a 680A inrush current rating and resistive load switch capacity. It features a two-pole, normally-open or normally-closed contacts, and an MOSFET drive for enhanced reliability. The PJR220A also offers excellent surge protection and is designed to be resistant to vibration and shock. With an insulation resistance of up to 50 megohms, it provides superior protection against electrical disturbances.

The PJR220A is designed to be used in a wide range of applications that involve high current arcs of 2 amps or more. These include:

• Automotive - Ignition and starting systems, lighting systems, car alarms.
• Industrial - Sensors, motors, solenoids, and other electrical circuits.
• Home Security - Security systems, garage door openers, visors, etc.

The PJR220A is designed to protect against short-circuits, surges, and overloads, and can be used in a variety of applications that require high current arcs of 2 amps or more. This makes it an ideal choice for applications that need to maximize performance and reliability.

The PJR220A is based on electromagnetic principles, meaning that it works by using a force produced by a magnetic field to open or close the contact points. When the force is applied, an armature is attracted to the electromagnet, causing the contact points to close or open. This is referred to as the change-over function of the PJR220A.

The PJR220A also features thermal protection, which helps to ensure optimal performance and protect against overloads. When the current exceeds the specified rating, the thermal trip will open the contacts, preventing further damage.

The PJR220A is designed to provide reliable performance even in harsh environments, such as in high heat or vibration. It is constructed from durable materials, such as polyester, and can withstand temperatures up to 85℃. It is also designed to be resistant to vibration and shock, making it ideal for use in mobile applications.

Overall, the PJR220A is a reliable power relay designed for uses that require high current arcs of 2 amps or more. It is designed to provide outstanding performance and protection against short-circuits, surges, and overloads. It is an excellent choice for automotive, industrial, and home security uses.
