Overview

Solid-state overcurrent protectors encompass products that are generally used to provide supplementary protection for the load-side of an isolating transformer, power supply or battery. These low-voltage protectors are rated for voltage range, maximum continuous current, protective current and suitability for use in telecommunications network connections.

These protectors are used in common consumer devices such as computer systems as well as in industry related applications – they are not stand-alone devices and the end product must be evaluated and certified for safety. These devices are provided with no means for manual operation or reset.

Devices can be rated to a maximum current limit of 5A, with a maximum input voltage of 30VAC, 60VDC. These protectors are either integrated circuits, intended to be mounted to a printed wiring board or a component/modular type device.

Solid state manufacturers develop these protectors for use in the end-use, consumer electronic-type devices.

Services

We provide the following services for solid state protectors:
  • U.S. – UL 2367, UL Mark Recognition
  • International – IEC 60950 (Annex CC) and IEC 62368-1 (Annex G.9), CB Certification and Test Certificate

Standard information

  • IEC 62368-1 Edition 3 is currently published and will be adopted by Europe in mid-to-late 2019.
  • IEC 62368-1 Edition 2 will still be available for evaluation and used by various countries for several years until Edition 3 is adopted and mandated. At that time, Edition 2 will be phased out and fully replaced by edition 3. Until that time, Edition 2 and 3 will be concurrently available for certification for such countries.
  • National differences to IEC 62368-1 will not be released for approximately one year – the current edition does not have any differences that affect solid-state overcurrent protectors. 

Area of expertise

We provide services for the following types of solid-state protectors:
  • Special purpose solid-state overcurrent protectors
  • Low-voltage overcurrent protectors

Benefits

We offer a CB Test Report/Certificate to IEC 60950 Annex CC Test Plan 2 and IEC 62368 Ed.2 Annex G.9. This streamlined certification process and harmonized test plan for the applicable standards – UL 2367/IEC 60950/IEC 62368 Ed.2 and Ed.3 – helps saves time and money through a well-proven global certification program. Additionally, end-product manufacturers can streamline certification by selecting components that are already UL certified.
