Surge generator

D.U.T.

This is a GO-NO GO test which allows to confirm the holding current (I

) level in a functional test circuit.

TEST PROCEDURE :

- Adjust the current level at the I

value by short circuiting the D.U.T.

- Fire the D.U.T. with a surge current : I

= 10A, 10/1000

- The D.U.T. will come back to the off-state within 50 ms max.
