MDH200H5 LED screen power supply
The Rong-Electric MDH200H5, also described as Rongdian in the original listing, supplies 5 V DC for compatible LED display modules. The listing identifies it as a constant-voltage model with 40 A output and 200 W maximum power. For a transparent LED wall or other cabinet, match the module voltage, load and mounting requirements before selection.

Revision and mounting checks
The linked V1.0 PDF is dated February 29, 2016. Its dimensional section is also inconsistent: the English line gives 142 × 58.8 × 30 mm, while the Chinese line gives a 58.5 mm width. These differ from the original page’s 58 mm width. Confirm the actual unit and mechanical drawing before setting mounting clearances.
The table distinguishes the original listing from the PDF instead of combining conflicting values into a single assumed specification. Confirm the supplied revision’s input, efficiency, storage limits and mechanical details. Preserve ventilation and follow the applicable installation and derating instructions.

Frequently asked questions
What are the MDH200H5 voltage and current ratings?
The original listing specifies a constant-voltage 5 V output, 40 A current and 200 W maximum power. The PDF gives an output-current range of 0–40 A.
Can it power a transparent LED wall?
It can be considered for compatible 5 V LED modules, but suitability depends on the cabinet load, wiring, mounting and thermal conditions. The product name alone does not establish compatibility with every transparent screen.
What AC input range should I use?
The original listing says 186–264 Vac, while the linked V1.0 PDF says 190–264 Vac operating input and 200–240 Vac rated input. Confirm the supplied unit’s nameplate and revision. Neither source establishes 110 V compatibility.
What is the correct enclosure width?
The page and PDF contain 58 mm, 58.8 mm and 58.5 mm width entries. Verify the actual unit and applicable drawing before planning mounting clearance; the difference is not resolved by the available documents.
Where can I download the MDH200H5 specification?
The original manufacturer PDF is linked above, together with all three original product photos. Review the documented differences before applying its parameters.
