What is IEC 60320-4:2019 ?

IEC 60320-4:2019 is an essential international standard for connectors used in electronic devices. It is widely recognized for its ability to ensure safety, compatibility, and reliability in various technical applications. In this article, we will delve into the main features and purpose of IEC 60320-4:2019.

IEC 60320-4:2019 is a technical document published by the International Electrotechnical Commission (IEC) that specifies the safety requirements for appliance couplers used in electronic equipment. The standard is divided into four parts, each covering a different aspect of the appliance coupler design and construction.

The first part, IEC 60320-4-1:2019, defines the general requirements for the design, construction, and testing of appliance couplers. This part covers the basic principles of the standard, such as the use of uninterruptible power supply (UPS), grounding, and labeling requirements.

The second part, IEC 60320-4-2:2019, defines the specific requirements for the electrical performance and environmental characteristics of the appliance coupler. This part evaluates the electrical performance, such as the maximum voltage and current ratings, as well as the device's resistance to environmental stress, such as temperature, humidity, and vibration.

The third part, IEC 60320-4-3:2019, defines the requirements for the mechanical design and construction of the appliance coupler. This part covers the mechanical design requirements, including the use of compatible materials, the minimum dimensions, and the need for flexibility in order to accommodate different connection configurations.

The fourth and final part, IEC 60320-4-4:2019, defines the requirements for the testing and certification of the appliance coupler. This part outlines the testing procedures and requirements for the electrical, mechanical, and environmental performance tests.

In conclusion, IEC 60320-4:2019 is an essential international standard for the design, construction, and testing of appliance couplers used in electronic equipment. It ensures the safe connection of electronic devices to the power supply, minimizing the risks of electric shock, fire, and other hazards associated with improper connections or faulty couplers. By following the guidelines and requirements set out in this standard, manufacturers can create safer and more reliable appliance couplers for a wide range of electronic devices..
