Dual 4.2V and 3.2V outputs for LED equipment
The XingXiu DSP500B-4232 provides two DC rails from a 100–240V AC nominal supply. Its specified rated output power is 385W, with typical efficiency of 90% at 230V AC and full load.
This LLC power supply uses input-to-output isolation and ventilation cooling in a 180 × 68 × 26mm enclosure. When replacing a dual-rail supply, compare each load requirement and the terminal layout using the specification PDF; matching total power alone is not enough.
