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.
