What is CSA C22.2 No. 247-14?

CSA C22.2 No. 247-14 is a professional technical standard that specifies the safety requirements for information technology equipment (ITE) power supplies, including those with multiple output ports. It was developed by the Canadian Standards Association (CSA), an independent organization responsible for creating and updating standards in Canada. In this article, we will explore the key features of CSA C22.2 No. 247-14 and its significance in ensuring the safety of ITE power supplies.

Scope and Purpose

The scope of CSA C22.2 No. 247-14 primarily covers ITE power supplies that convert electrical energy into usable power for electronic devices. It sets out specific safety requirements that such power supplies must meet to ensure the protection of users and minimize potential hazards. The purpose of this standard is to establish uniform criteria for the design, construction, and testing of ITE power supplies to guarantee their safe operation under normal conditions and during abnormal events.

Key Requirements

CSA C22.2 No. 247-14 outlines several crucial requirements that manufacturers must adhere to when producing ITE power supplies. These requirements include adequate insulation, proper grounding, thermal protection, fault current withstand capacity, and clear marking and labeling. Additionally, the standard mandates compliance with other relevant safety standards and regulations, such as electrical shock, fire, and energy efficiency standards, to ensure overall product safety and performance.

Compliance and Certification

In order to demonstrate compliance with CSA C22.2 No. 247-14, manufacturers are required to have their ITE power supplies tested and certified by accredited testing laboratories. The certification process involves rigorous testing procedures and inspections that evaluate the conformity of the power supplies with the standard's safety requirements. A certification mark from a recognized testing laboratory indicates that the product meets the necessary safety standards and can be used with confidence.

In conclusion, CSA C22.2 No. 247-14 plays a critical role in ensuring the safety and reliability of ITE power supplies. By establishing strict safety requirements and providing guidelines for compliance and certification, the standard helps protect users from potential hazards and ensures the proper functioning of electronic devices. Manufacturers must adhere to CSA C22.2 No. 247-14 to gain certification and demonstrate their commitment to producing safe and reliable ITE power supplies.
