In this video number {1081 } I explained how to repair delta electronics PMC-24V300W1BA 24 volt 12.5 ampere EOE13010225 switching power supply. its repair and troublshooting process was very complicated due to short circuit in power MOSFETs, their gate drive components, pulse trtansformer, PFC section rectifier S6J 6 amper, 600 volt SMC / DO-214AB rectifier, A2 smd marking zener diode UDZV 5.1B 5.1 volt zener diode
5IN smd diode MMSD4148 Switching diode, 200V, 200mA,
pulse transformer one winding open circuit
