300W LED power supply with 5V DC output
The XingXiu DSP300V-5 combines a 300W rated output with a 5V DC supply for LED display equipment. It uses LLC conversion technology and isolates the AC input from the DC output.
The published efficiency figure is a minimum of 90% at 230V AC and full load. Its 90–264V AC input range covers nominal 100–240V supplies. The table below brings together the electrical and enclosure specifications for checking a cabinet installation.

Frequently asked questions
What is the DSP300V-5 designed to supply?
This model supplies 5V DC with a rated output power of 300W for equipment such as LED displays. The connected load must meet its electrical specifications.
What AC input range does it accept?
The input range is 90–264V AC at 47–63Hz. The nominal input range is 100–240V AC.
What does the 90% efficiency figure mean?
The specification lists a minimum efficiency of 90% at 230V AC and full load. Use those conditions when comparing it with another supply.
Will it fit in the same space as my existing power supply?
The case measures 208 × 60 × 30mm. Compare the mounting points and terminal layout in the linked PDF as well as the outer dimensions; similar dimensions alone do not confirm fit.
