The XingXiu DSP400L-0304-BA power supply converts AC mains input into two regulated DC output channels: 4.2VDC and 3.2VDC. It provides 321W normal output power for compatible LED display systems and industrial electronic equipment.
The BA version uses an LLC conversion topology with precise control and input-to-output isolation. Its 90-264VAC input range supports common 100-240VAC installations, while the dual low-voltage outputs serve equipment designed specifically for 4.2V and 3.2V rails.
Model suffixes matter. The DSP400L-0304-BA is not interchangeable with a similarly named power supply unless the output voltages, connector layout, pinout, power demand, mounting dimensions, and cooling requirements all match.
