Surge generator
This is a GO-NO GO test which allows to confirm the holding current (IH) level in a functional test circuit.
TEST PROCEDURE :
- Adjust the current level at the IHvalue by short circuiting the D.U.T.
- Fire the D.U.T. with a surge current : Ipp= 10A, 10/1000 µs.
- The D.U.T. will come back to the off-state within 50 ms max.
