R2 240 220V k Vout IBO measure D.U.T VBO measure Transformer 220V/800V 5A TEST PROCEDURE : Pulse Test duration (tp = 20ms): - For Bidirectional devices = Sw itchK is closed - For Unidirectional devices = Sw itch K is open. VOUT Selection - Device w ith VBO < 200 Volt - VOUT = 250 VRMS, R1 = 140 Ω. - Device w ith VBO 200 Volt - VOUT = 480 VRMS, R2 = 240Ω. TEST CIRCUIT 2 FOR IH PARAMETER: R VBAT=-48V D.U.T. Vp Surge generator This is a GO-NO GOTest which allows to confirm the holding current (IH) level in a functionaltest circuit. TEST PROCEDURE : 1) Adjust the current level at the IH value by short circuiting the D.U.T. 2) Fire the D.U.T with a surge current : Ipp = 10A , 10/1000µ s. 3) The D.U.T will come back off-state within 50ms max. www.galaxycn.com Document Number 0286006 BLGALAXY ELECTRICAL 3.
