What are the Vibration test condition for the GV2 range of MPCB and Is there any relation between the gn value & mm value in the Vibration test.

Shock resistance and Vibration tests are done at hot state (never cold state) corresponding to the maximal current of the rating. The standard reference is IEC 60068-2-6.

For the Vibrations Tests

5-150Hz ==> freq (low), +/- 10 mm / 5g / 5 cycles - 30mn / resonance frequency)

>> 5 g regards the acceleration : the law of gravity involves the acceleration of a mass and is expressed by the letter g. Number at gn is multiply of gravity constant g. See attachment for more explanation.
