5V 40A power for LED display cabinets
The Rong-Electric MDH200PC5 is a 200W LED display power supply with a 5V DC output and a 0–40A output current range. Its rated 100–240VAC input supports installations using either 110V or 220V mains within the specified limits.
The model-specific specification lists input undervoltage, output current limiting and short-circuit protection, together with ventilation/self-cooling. Check the LED module load, cabinet conditions and terminal layout before selecting a replacement.

Efficiency and installation notes
The input characteristics table gives ≥89% efficiency at 220VAC, full load and room temperature. The document overview says 86% or above without the same test detail. Use the condition-specific table value when comparing supplies, and confirm the specification revision for the unit being purchased.
The 10–50% operating relative humidity range above follows the environmental table as printed. For a high-humidity installation, state the requirement when ordering and confirm the appropriate product version. Check the cooling path and mounting arrangement in the LED cabinet before installation.
Frequently asked questions
What is the MDH200PC5 output rating?
The MDH200PC5 specification lists 5V DC, a 0–40A output current range and 200W output power. Confirm that the LED modules and wiring match these ratings.
Can the MDH200PC5 use a 110V or 220V AC supply?
Both are within its 100–240VAC rated input range. The input characteristics table separately lists an operating input range of 90–264VAC and a frequency range of 47–63Hz.
What efficiency does the specification list?
The input characteristics table specifies at least 89% at 220VAC, full load and room temperature. The overview contains a less specific statement of 86% or above; efficiency should be compared using the stated test conditions.
What cooling and humidity conditions should I check?
The environmental table lists ventilation/self-cooling, −30 to +60°C operation and 10–50% operating relative humidity. The document asks buyers to specify high-humidity requirements when ordering. Confirm the cabinet conditions and installation arrangement for the supplied version.
Can it replace another 5V 40A LED power supply?
Matching voltage and current alone does not establish compatibility. Check the exact model, AC input, mounting dimensions, terminal arrangement, wiring and cabinet cooling before replacing an existing supply.
