321W dual-output supply with three voltage settings per rail
The XingXiu DSP400L-0304-BA provides nominal 4.2V/49.7A and 3.2V/35A DC outputs from an AC input. The V1.0 specification lists three jumper settings on each rail, allowing selection of 3.8/4.0/4.2V for V1 and 2.8/3.0/3.2V for V2.
The BA suffix identifies the version described here. Use its own electrical ratings when planning a replacement: related DSP400L models have different nominal outputs. This version uses LLC conversion, input-to-output isolation and ventilation cooling.

Frequently asked questions
What output ratings apply to the DSP400L-0304-BA?
The specification lists V1 at 4.2V/49.7A and V2 at 3.2V/35A, with a rated output power of 321W.
How are the output voltages selected?
Each output has three jumper-selectable settings: 3.8/4.0/4.2V for V1 and 2.8/3.0/3.2V for V2. Match each setting to the connected load.
Is the BA version identical to DSP400L-0304?
Do not use the two model names interchangeably. The BA specification lists 4.2V/49.7A and 3.2V/35A nominal outputs, while the DSP400L-0304 specification lists 3.8V/55A and 2.8V/35A. Use the document for the exact version being installed.
What AC supply does this version require?
The full input range is 90–264V AC at 47–63Hz, with a nominal input range of 100–240V AC.
What size is the BA power supply?
The listed dimensions are 180 × 68 × 26mm. Verify mounting, terminals and ventilation space using the original specification PDF.
