빠른 답변 : The XingXiu DSP400L-0304 power supply converts AC mains input into two regulated DC output channels: 3.8VDC and 2.8VDC. It is rated for 307W normal output power and is intended for compatible LED display systems and industrial electronic equipment.
XingXiu DSP400L-0304 power supply overview
The DSP400L-0304 uses an LLC conversion topology with precise control and input-to-output isolation. Its wide 90-264VAC input range supports common 100-240VAC installations, while the dual low-voltage outputs serve equipment designed specifically for 3.8V and 2.8V rails.
This is not a universal replacement for a standard 5V LED power supply. Confirm the required voltage rails, connector layout, power demand, mounting space, and cooling conditions before ordering or installing it.
