5V power supply for transparent LED video walls
The Rong-Electric MDH200H5 is listed as a constant-voltage LED screen power supply with a 5V, 40A output and 200W maximum output power. The original listing gives housing dimensions of 142 × 58 × 30mm for checking clearance in a transparent LED display cabinet.
The original product information and linked MDH200H5 PDF contain several parameter differences. The table below keeps these values separate so the supplied version can be checked before ordering or installation.
MDH200H5 specifications and source notes

Confirm the supplied version
The PDF input table states 190–264VAC, while its explanatory note also mentions 180–264VAC. The original listing states 186–264VAC. These lower limits have not been reconciled; use the supplied unit’s nameplate and matching manufacturer specification to confirm the permissible input.
Check the efficiency and storage-temperature differences in the table as well. For cabinet installation, compare the mounting holes, terminal layout and ventilation path with the existing supply. The listed standards are references, not evidence of a certification certificate for the individual unit.
Frequently asked questions
What is the output of the MDH200H5?
The listing identifies a constant-voltage 5V, 40A power supply with a maximum output power of 200W. The model-specific PDF gives a 0–40A output current range.
Can I use MDH200H5 on 110V AC?
110VAC is outside both the original listed input range and the PDF input range. The PDF rates the input at 200–240VAC. Check the supplied unit’s nameplate before connection.
What are the dimensions for a transparent LED wall installation?
The original listing gives 142 × 58 × 30mm. Check the actual supply, mounting holes, terminal clearance and cabinet cooling before replacing a unit in a transparent LED video wall.
Why do the listing and PDF show different parameters?
The available sources differ on the input lower limit, efficiency and storage temperature, and express ripple differently. The table preserves both sets with their sources. The materials do not establish the reason for these differences; confirm the matching revision for the supplied unit.
Can MDH200H5 replace any 5V 40A power supply?
No universal interchangeability is established. Match the model, AC input, DC output, mounting dimensions, terminal arrangement and operating conditions. Resolve the source differences before using those limits in a design.
