Quick answer: 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.

Frequently asked questions
What are the DSP400L-0304 output voltages?
It provides two DC output channels: 3.8VDC and 2.8VDC. The connected equipment must be designed for these voltage rails.
What input voltage does the DSP400L-0304 accept?
The listed input range is 90-264VAC at 47-63Hz. The normal operating input range is 100-240VAC.
What is the rated output power?
The listed normal output power is 307W. Always confirm the actual load and required output distribution before installation.
Can the XingXiu DSP400L-0304 power supply replace a standard 5V unit?
Not as a direct universal replacement. The DSP400L-0304 provides 3.8VDC and 2.8VDC outputs, so voltage, connector, pinout, power, and mechanical compatibility must all be verified.
What are the power supply dimensions?
The enclosure measures 180 x 68 x 26 mm. Allow additional space for connectors, cable bend radius, mounting, and airflow.
