I have a 24V 10A smps essen make model EPS 240-24 . I have not any schematic .
problem unit is dead . first I check it and found some components are faulty ,I replace it but no responce . I changes , C3320, 3040 schootky diode , 2654 transistor 33v zener & also replace two condenser 470uF/200V . I do not understand how the smps works , there is no initial power in the Controll IC TL494 ,so how it will be started . or from where starting voltage will be induced ?
