Abstract
An overvoltage protection device that can be adapted to a programmable automaton power supply, including: a first detection and protection device configured to detect a possible overvoltage at a first point of a primary or secondary circuit, and including a mechanism triggering a short-circuit if an overvoltage is detected at the first point such as to stop all energy transfer toward the output of said power supply; and a second detection and protection device configured to detect a possible overvoltage at a second point of the primary or secondary circuit, and including a mechanism triggering a short-circuit if an overvoltage is detected at the second point such as to stop all energy transfer toward the output of said power supply; and a thyristor having an independent power supply and configured to maintain, by memory effect, the short-circuit that may have occurred.
