Published values that need revision confirmation
| Item | Original product table | Linked PDF |
|---|---|---|
| Output current | 80A maximum; a separate current range of 0–60A | 80A rated; 82A peak |
| Efficiency | 86% | ≥80% at full load |
| Inrush current | ≤40A | ≤66A at 220VAC |
| Leakage current | ≤2.0mA | ≤0.25mA at 220VAC |
| Start/rise time | “Start Time”: 50ms | Output rise time: ≤50ms; power-on delay is listed separately as ≤6s at −40°C to −5°C and ≤5s at ≥25°C, with 220VAC input |
The original listing gives dimensions of 212 × 85 × 30mm, fan-forced cooling and an operating temperature of −30°C to +60°C. Confirm the mechanical fit and temperature/load requirements for the supplied revision before ordering. The PDF includes input-voltage and temperature loading curves; the full 400W rating should not be assumed for every operating condition.
Ordering a replacement
Match the complete model number, required 5V output, cabinet load, terminal arrangement and mounting clearance. Confirm the current unit price and shipping cost for the required quantity. If the existing label differs from the PDF or the values above, obtain the matching revision specification before choosing a replacement.
Frequently asked questions
Is the YY-D-400-5 rated for 5V 80A output?
Yes. The linked PDF lists 5V DC, 80A rated output and 400W normal output power. It lists 82A separately as peak current. The older listing’s 0–60A range is recorded above as a discrepancy requiring revision confirmation.
Can the YY-D-400-5 operate from 110V AC?
110VAC is outside the published input range. The PDF gives a normal input of 200–240VAC and an input-voltage range of 180–260VAC, with an input-voltage derating curve.
Does this power supply use a cooling fan?
The original listing specifies fan-forced cooling and describes temperature-controlled fan speed. Allow for the cabinet’s airflow and service access when checking the installation.
Why do some ratings differ between the product listing and PDF?
The available sources do not establish the reason. The differences are shown above rather than combined into one assumed rating. Confirm the nameplate and specification revision for the unit being ordered.
Where can I download the YOUYI YY-D-400-5 datasheet?
The original specification PDF is linked below the product photos. It includes electrical ratings and loading curves for YY-D-400-5.
