High-Current Regulated Power Supply Board Adjustable Step-Down Converter for Experimental Setups Automotive Modification

High-Current Regulated Power Supply Board Adjustable Step-Down Converter for Experimental Setups Automotive Modification Description

Dual-Input Operating Mode: Supports both AC and inputs via dedicated onboard . The AC input does not require polarity distinction, allowing for flexible and convenient wiring.
Synchronous Buck Rectification: Utilizes a synchronous step-down (buck) circuit architecture, offering higher conversion efficiency and lower heat generation compared to traditional designs.
Onboard 15A High-Current Rectifier Bridge: Features a built-in 15A rectifier bridge, enabling direct input from low-voltage AC .
High-Quality Sendust (FeSiAl) Inductor: Equipped with a 10A-rated Sendust inductor, ensuring excellent resistance to magnetic saturation and stable power delivery even under high-current loads.
Continuously Adjustable Wide-Range Voltage: The output voltage can be precisely and linearly adjusted from 3.3V to 32V, meeting the diverse power supply requirements for various experiments and engineering projects.
