![]() Note that the primary is kept LO as this has the DC1000 attached. ![]() Check leakage inductance to all other coils is less than 12 uHĬhecks coupling of coils is good to minimise leakageĤ.5 kV AC, 1 second, Pins 8,9,10,11 Hi, Pins 2,3,4,5,6 Lo. ![]() Hence allows you to prove on every part that L drop under Bias is not greater than published 20%Įnergise pins 4-2, 0.1 V, 10 kHz. Check inductance to be >368 uHĬheck core does not saturate under DC. To check correct ratio of windings from all of primary to feedback windingĮnergise Pins 4-2, 0.1 V, 10 kHz, measure inductance to be 461 uH +/- 10%Ĭheck core material and assembly accuracyĮnergise Pins 4-2, 0.1 V, 10 kHz, apply 3.15 A DC. To check correct ratio of windings from all of primary to the other secondaryĮnergise pins 4-2,0.1 V 10 kHz. To check correct ratio of windings from all of primary to one of the secondariesĮnergise pins 4-2,0.1 V 10 kHz. To check correct ratio of windings from each side of the primary centre tapĮnergise pins 4-2,0.1 V 10 kHz. Also acts as a check of correct wire gauge and good termination.Įnergise pins 4-3,0.1 V 10 kHz. To check the winding resistance is below a maximum.
