Rong-Electric MNS400PC5 5V 80A LED Power Supply
$ 22.00
The Rong-Electric MNS400PC5 is a narrow 5 V DC, 80 A, 400 W LED power supply measuring 220 × 47 × 26 mm. Its specification requires an auxiliary cooling plate and reduces permitted load at low AC input voltage.

MNS400PC5 narrow power supply: mounting and load selection
The Rong-Electric MNS400PC5 specification describes a narrow supply for LED display applications, with nominal 5 V DC output and a 400 W rating. Its 220 × 47 × 26 mm housing is paired with an explicit requirement for an additional heat-dissipation plate.
Use the cabinet temperature, input voltage and cooling arrangement when selecting the load. The low-line curve calls for reduced output below the full-load input region. The environmental table limits operation to +50°C; the higher temperatures drawn on the graph are recorded as a source discrepancy rather than an expanded operating rating.

Frequently asked questions
How much power is available from MNS400PC5 at 110 V AC?
The input curve specifies 80% load at the plotted points from 90 to 160 V AC, including 110 V. The 400 W nominal rating therefore is not a full-load allowance at 110 V AC. Follow the derating curve and cooling requirements.
Does the narrow power supply need an additional heatsink?
Yes. The environmental-table note specifies a 400 × 400 × 3.0 mm heat-dissipation plate under the supply. Its compact 220 × 47 × 26 mm housing does not remove that installation requirement.
Can it be used at 70°C because the curve includes that temperature?
The environmental table specifies operation from −30°C to +50°C. The graph extends to 70°C, creating a documentation difference. Obtain confirmation for the actual unit before using it above the table’s +50°C limit.
What are the output terminals?
The PDF gives two GND connections followed by two +5 V connections when facing the output terminals from left to right. Confirm the markings on the actual power supply and use the mechanical drawing for the installation.
Is the 88–120 A figure the usable output current?
No. The output-current rating is 0–80 A. The 88–120 A range is the overcurrent-protection threshold; the specified recovery mode is hiccup with automatic recovery.
