Importance of power supply (PSU) testing and certification

Power supply units are used to convert alternating current (AC) input voltage into low-voltage direct current (DC) input. Our evaluations help ensure safer use of these devices when applied in industrial and commercial equipment in office (commercial) and factory (industrial) applications.

UL 508 and IEC 61010

With combined testing or transitioning of industrial power supplies from UL 508 to IEC/UL/EN 61010-2-201, manufacturers can streamline and accelerate certification with one cost-efficient, quick and easy path. We can test your products to required standards for safety, sustainability, performance and quality. We work with you to support your drive to get your products to market as quickly and efficiently as possible.

PSU safety testing and certification services

Streamline your global market access for industrial power supplies with CB, CE and/or UL Mark Certification. In response to the industry’s harmonization requests, we now offer an alternate path to certification for power supplies with IEC/UL/EN 61010-2-201.

Whether you are planning power supply production for U.S. markets or international markets, we will help you from start to finish with your compliance and certification needs.

IEC 62368-1

Today’s audio/visual (AV) and information communication technology (ICT) equipment relies on robust but safe operating power supply units as a critical component in its overall product design. These power supplies can directly power the equipment or function as a battery charger for portable battery-powered products. They also can be an external component that plugs into the wall or an internal component that is built into the end product.

IEC 62368-1 is the internationally recognized safety standard that tests and certifies power supplies to ensure safe use of these components within the product system. The standard is based on a hazard-based safety engineering approach and replaces standards IEC 60950-1 and IEC 60065. For additional resources related to IEC 62368-1, visit our service page.

For complex power supplies, UL Solutions can offer an early design assessment so that any safety-critical gaps in meeting the requirements of the standard can be identified and addressed early in the design phase. This can be followed up or combined with the final certification to meet required deadlines. Here is a list of services provided by UL Solutions for power supplies that fall under scope of IEC 62368-1:

  • Preliminary design review services
  • Certification services
  • Testing services
  • Training and advisory services

For global market access countries may require different versions of the standard. UL Solutions can assist in mapping out these requirements so that any national differences can be identified and met.
