Functional Holding Current (I
Test circuit for V
(V is defined in unload condition)
V
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
- The D.U.T. will come back to the off-state within a duration of 50ms max.
