The YuanChi YC-400W16-5V is a 5V LED screen power supply rated at 80A and 400W. It uses a normal 200–240VAC input and is intended for installations that require a compatible 5V DC supply.
The specification lists 85A as peak current. Use the 80A rated current and the manufacturer’s derating curves when checking the continuous load for an LED cabinet.

| Parameter | Specification |
|---|---|
| Model | YC-400W16-5V |
| Rated output | 5.0V DC, 80A |
| Rated output power | 400W |
| Output regulation | ±5% |
| Minimum output current | 0A |
| Peak output current | 85A; not the continuous rated current |
| Normal AC input | 200–240VAC |
| Input voltage range | 176–264VAC; input-voltage derating applies |
| Input frequency | 47–63Hz |
| Maximum AC input current | 4.9A at full load |
| Efficiency | 91% minimum at 230VAC, full load |
| Power factor | >0.95 at 220VAC |
| Cold-start inrush current | 80A at 220V |
| Leakage current | Less than 1mA at 230VAC input |
| Input fuse | T6.3AH/250VAC |
| Derating | Refer to the PDF input-voltage and temperature curves; the temperature curve reduces allowable load above 50°C |
Check the LED cabinet before ordering
Confirm the required DC voltage, total load, mounting arrangement and terminal connections against the existing power supply. The 176–264VAC input range does not mean full output is available throughout that range: the PDF provides a separate input-voltage derating curve. It also requires a reduced load above 50°C.
Frequently asked questions
What output does the YC-400W16-5V provide?
The specification gives a nominal 5.0V DC output, an 80A rated current and 400W rated output power. Apply the stated input-voltage and temperature derating conditions.
Is the YC-400W16-5V suitable for 110V AC?
No. Its published input range is 176–264VAC, with a normal input of 200–240VAC. A 110VAC supply falls outside that range.
Can I use 85A as the continuous output current?
No. YuanChi lists 85A as peak current and 80A as rated current. Size the continuous load using the rated current and the applicable derating curves.
Does output loading change at high temperature?
Yes. The specification includes a temperature derating curve that reduces the permitted load above 50°C. Check that curve together with the input-voltage curve before selecting the supply for a cabinet.
Where is the YC-400W16-5V specification PDF?
The original PDF download is below the product photos. It includes electrical ratings, derating curves and further installation information for this model.
