Cooling and model identification
Leave the fan and ventilation paths unobstructed. The PDF calls for an auxiliary heat-dissipation plate of at least 300 × 200 × 3 mm during high-temperature burn-in. Use the full document to assess the actual cabinet temperature, mounting and load conditions.
The original download filename below omits the final S, but the PDF cover and internal product headings identify MA300SH5S. Match the model printed on the supplied unit before replacing a MA300SH5 or another similar supply; matching voltage and wattage alone does not confirm interchangeability.

Frequently asked questions
What output does the MA300SH5S provide?
It provides +5 V DC with a 0–60 A output-current range and a listed rating of 300 W. The documented output-voltage range is 4.95–5.1 Vdc.
Does the MA300SH5S have a cooling fan?
Yes. The linked manufacturer specification lists fan-forced air cooling. Keep the air path clear and follow its thermal installation guidance.
Can this model run on 110 V mains?
The specified rated input is 200–240 Vac. Do not select it for a 110 V installation based on the information on this page.
What are the mounting dimensions?
The V1.0 PDF gives an enclosure size of 190 × 82 × 30 mm. Refer to its drawing for the mounting-hole layout.
Why does the PDF link name say MA300SH5?
That is the original filename and link label. The document itself identifies MA300SH5S on its cover and product headings; the original download URL has been retained.
