Working principle

This power module adopts the classic working architecture of "AC rectification DC filtering stabilized output":

Rectification stage: The external AC input voltage is converted into pulsating DC voltage through a bridge rectifier circuit, achieving the initial conversion from AC to DC.

Filtering stage: The pulsating DC voltage is filtered through a large capacity electrolytic capacitor to eliminate voltage fluctuations and form a smooth DC bus voltage.

Voltage stabilization stage: The microprocessor monitors the output voltage and current signals in real time, adjusts the conduction and turn off time of the power switch tube by controlling the duty cycle of the PWM waveform, and stabilizes the DC bus voltage at the rated output value.

Protection feedback: When the protection circuit detects an abnormal signal, it immediately sends an instruction to the microprocessor to cut off the output or adjust the working state, and at the same time feeds back the fault type through the indicator light.

Precautions

Installation specifications: Wiring must strictly follow the polarity markings, and reverse connection of input and output terminals is strictly prohibited; Reserve at least 50mm of heat dissipation space around the module to avoid direct contact with heating devices.

Operation safety: Before powering on, check whether the input voltage matches the rated range of the module; When repairing, the input power must be disconnected first, and the capacitor discharge must be completed (at least 5 minutes) before operation.

Environmental adaptation: Avoid use in environments with high dust, corrosive gases, or condensation. If installation is required in harsh environments, protective enclosures should be used.

Regular maintenance: Conduct a status check every 6 months, clean the surface dust of the module, check if the wiring terminals are loose, and test if the output voltage accuracy is normal.
