Rich Nute, IEEE Life Fellow

Various IEC safety standards describe in detail the safety requirements for “SELV.”  However, while acknowledging the concept of a “limited current source,” these same standards rarely describe the requirements for such a source.  This paper defines “hazardous live” parts and demonstrates how a limited current source is the current equivalent of a limited voltage source (SELV).
