264W dual-output power for LED displays
The XingXiu DSP300L-0304 converts AC input into two DC output rails for LED display equipment: 4.2V at 40A and 3.2V at 30A. Its LLC design provides input-to-output isolation, and jumper selection allows three voltage settings on each rail.
For cabinet integration or replacement, check the requirements of both loads rather than selecting by total wattage alone. The 180 × 68 × 26mm enclosure uses ventilation cooling; the specification includes input-voltage and temperature derating curves.

Frequently asked questions
What are the two outputs of the DSP300L-0304?
The nominal outputs are V1 at 4.2 V DC / 40 A and V2 at 3.2 V DC / 30 A. The specified rated output power is 264 W.
Can I select a different output voltage?
Yes. The specification lists jumper settings of 3.8, 4.0 or 4.2 V for V1 and 2.8, 3.0 or 3.2 V for V2. Match the selected voltage to the connected load before use.
Does it accept both 110 V and 230 V AC input?
Both are within the specified nominal input range of 100–240 V AC. The full input range is 90–264 V AC at 47–63 Hz; consult the PDF for input-voltage derating.
What size space does this power supply require?
The case measures 180 × 68 × 26 mm. Check the mounting drawing in the PDF as well as the space required for wiring and ventilation in your cabinet.
Can it replace any LED display power supply?
A replacement must match both output rails, the load current, input supply, terminal arrangement and mounting dimensions. A model name or similar case size alone does not establish compatibility.
