The YOU-YI YY-D-300-5 is a 5V DC, 60A power supply for LED displays, with 300W normal output power in its specification. It is designed for a normal 200–240VAC supply and uses the input-voltage loading conditions shown in the linked PDF.
YY-D-300-5 specifications
The electrical values below are taken from the model-specific PDF. Keep the rated 60A output separate from the 62A peak-current figure when checking a cabinet load.
| Parameter | PDF value |
|---|---|
| Model | YY-D-300-5 |
| Rated DC output | 5V, 60A |
| Normal output power | 300W |
| Peak output current | 62A |
| No-load setting accuracy | ±0.05V |
| Regulation | ±2% |
| Normal AC input | 200–240VAC |
| Input voltage range | 176–264VAC; input-voltage derating applies |
| Input frequency | 47–63Hz |
| Maximum AC input current | 3.5A |
| Full-load efficiency | ≥83% |
| Inrush current | ≤65A at 220VAC |
| Leakage current | ≤0.25mA at 220VAC |
| Output rise time | ≤50ms at 220VAC and full load |
| Power-on delay | ≤6s at −40°C to −5°C; ≤3s at ≥25°C, with 220VAC input |
Source differences to check before ordering
The older listing and the PDF do not agree on every electrical value. The original values are recorded here so they are not mistaken for confirmed ratings for the delivered revision.
| Parameter | Original listing | Linked PDF |
|---|---|---|
| Efficiency | 86% | ≥83% at full load |
| Inrush current | ≤40A | ≤65A at 220VAC |
| Leakage current | ≤2.0mA | ≤0.25mA at 220VAC |
The original product table lists dimensions of 212 × 85 × 30mm, fan-forced cooling, −30°C to +60°C operating temperature and 20–90% RH non-condensing operating humidity. Confirm these installation details for the supplied revision. The PDF’s temperature and input-voltage curves should be used when determining the permissible load.
Replacement checks for a 5V LED cabinet
Compare the original power supply’s model, output voltage, load, terminal positions and mounting clearance. Keep ventilation paths clear for the listed fan cooling. The older listing includes EMC and certification references, but those references alone do not establish certification for a particular delivered unit; request matching documentation where required.
Frequently asked questions
What output is the YY-D-300-5 rated for?
The model-specific PDF lists 5V DC, 60A rated output and 300W normal output power. The peak current is listed separately as 62A.
Does the YY-D-300-5 support 110V input?
No 110VAC input is specified. The PDF gives a normal range of 200–240VAC and an input range of 176–264VAC with input-voltage derating.
Is the supply fan cooled, and what size is listed?
The original product table specifies fan-forced cooling and dimensions of 212 × 85 × 30mm. Confirm the mounting points and cabinet clearance against the supplied revision.
Why is the PDF efficiency different from the older product table?
The sources list different values: 86% in the original table and ≥83% at full load in the PDF. The available documentation does not explain the difference. Confirm the applicable revision rather than assuming one figure applies to every unit.
Where can I download the YY-D-300-5 specification?
The original specification link remains below the product image. The document includes input and output parameters, loading curves and additional installation details.
