Inside iCoupler® Technology:
IEC 61010-1 Edition 3
International standard IEC 61010-1 specifies safety requirements for a variety of electrical systems, including test and measurement, industrial process-control and laboratory equipment. The purpose of the standard is to minimize hazards to operators and the surrounding environment and equipment. The first edition was published in 1990, with the most recent third edition having been released in 2010. Many new elements were added in the third edition, including a complete rewrite of the section governing insulation requirements. This note discusses new requirements for thin film insulation and the impact on digital isolators utilizing this material as the isolation barrier.
