Shock test consists of pivoting the power supply, from one edge of it’s bottom side, on a flat surface

(such as wood having thickness of 10mm or more)

and allowing the opposite edge to fall from a height

of 50mm to this surface. The test is performed three times on each edge of

the bottom side of the power supply
