AC input power passes through EMI filter, rectifier and PFC circuit to complete preliminary power conditioning. The high-frequency switching circuit converts intermediate DC voltage into high-frequency AC, which is isolated and stepped down by high-frequency transformer. After rectification and filtering, stable 24 V DC power is output to load equipment. The built-in sampling circuit monitors output parameters in real time and triggers protection actions once abnormal states occur.
