Power Relays, Over 2 Amps: PT380220 Application Field and Working Principle

Developed by CHNT Relays, the PT380220 power relay is a secure, reliable, and durable device built for use in multiple industry applications. With a current rating of over two amps, PT380220 is an increasingly popular component in a range of products from diagnostic equipment, remote machinery control, industrial automation, lighting control, and even aircraft systems.

The PT380220 can withstand up to 4kV of surge current, making it suitable for use under the most rigorous and demanding conditions. The power relay is designed for a wide range of temperatures, from -50° to 125°. This makes it ideal for controlling equipment in extremely hot and cold locations, such as an industrial factory or a harsh outdoor environment.

The PT380220 is available in through-hole and surface mount packages, allowing it to fit into cramped spaces and complicated wiring systems, as well as mounting on printed circuit boards. It can be ordered with an optional base and contact block for easier installation and maintenance.

The PT380220 features an isolation rating of 4kV, which is designed to protect other components and circuits from electric shock. It also has a high contact rating of 40A and a voltage rating of 48VAC/250VAC/30VDC. Additionally, the PT380220 has a surge withstand capacity of up to 5,000 amps, making it perfect for providing power to high power devices such as motors or transformers.

The PT380220 relay has a working principle based on electromagnetism. When an electric current is passed through the various contact blocks, it creates a magnetic field that then attracts the armature. This movement of the armature completes the circuit, allowing electric current to flow through the relay. The armature is held in place by a spring which pushes against the armature when the electrical current is not flowing, effectively stopping the flow of current.

The PT380220 is a great choice for those in the industrial and aerospace industries who need a reliable and durable power relay for controlling a variety of devices. Its robust design and surge current rating make it suitable for the most demanding applications, while its wide range of packages allow it to fit into almost any space. With its high contact rating and voltage rating, it is perfect for powering devices such as motors and transformers, making it a great choice for powering a variety of different devices.
