FUNCTIONAL HOLDING CURRENT (IH) TEST CIRCUIT = GO - NOGO TEST.

-Vpp

Vbat = - 48V

Ipp = 10A,10/1000 s

VSGL

This is a GO-NOGO Test which allows to confirm the holding current (IH) level in a functional

test circuit.

This test can be performedif the reference test circuit can’t be implemented.

TEST PROCEDURE :

1) Adjust the current level at the IH value by short circuiting the AK of the D.U.T.

2) Fire the D.U.T with a surge Current : Ipp = 10A , 10/1000

µs.

3) The D.U.T will come back to the OFF-State within a duration of 50 ms max.

The VSGL is measured just before firing
