The XINGXIU DSP800A-3242 is a dual output LED display power supply with nominal 4.2V and 3.2V DC channels. The specification lists 676W normal output power and a normal AC input of 100–240V.
The available output current depends on the AC input. Check both channel loads against the appropriate input range, rather than using the higher current figures for every installation.

Choosing a dual voltage supply
Confirm that the LED module requires the two stated supply voltages, then check its load on each channel. This is not a standard single-output 5V supply. Match the terminal arrangement and mounting dimensions to the existing installation, and use the model-specific PDF for loading and connection details.
Frequently asked questions
What voltages does the DSP800A-3242 output?
It has two nominal DC outputs: V1 at 4.2V and V2 at 3.2V. Their published adjustment ranges are 4.2–4.6V and 3.2–3.6V respectively.
What are the output current limits on 110V AC?
110VAC falls within the PDF cover’s 100–179.9VAC band, which lists 80A for the 4.2V channel and 64A for the 3.2V channel. Check the PDF loading curves for the complete operating conditions.
Does the model number mean this is an 800W power supply?
No. The linked specification states 676W normal output power. The model name should not be used as a substitute for that rating.
Can it directly replace a single-output 5V LED power supply?
Do not assume that it can. Its two outputs have different nominal voltages and neither published adjustment range reaches 5V. Confirm the LED module’s required voltages and wiring before choosing a replacement.
Where is the DSP800A-3242 datasheet?
The original specification PDF is linked below the product photos. It includes the input-dependent channel ratings, electrical parameters and loading curves.
