The traditional over-voltage protection utilizes an element which short-circuits across the input or output lines of the supply in response to over-voltage sensing. This short-circuiting is referred to as a "crow-bar", and is very often a silicon controlled rectifier (SCR). The "crow-bar" acts as a short circuit, causing a fuse or circuit breaker to open. Such a system is sensitive to noise and is nonreversible, i.e., it requires manual intervention to turn a regulator back on after it has tripped.
