MD200PC5 power supply for LED display cabinets
The Rong-Electric MD200PC5 provides a 5V DC output with a 0–40A current range and 200W output power. Its rated 100–240VAC input covers both 110V and 220V AC installations within the specified limits.
Designed for LED displays, this model includes input undervoltage protection, output current limiting and short-circuit protection. The specification gives efficiency of at least 88% at 220VAC, full load and room temperature.

Installation and replacement checks
Use the input table’s 100–240VAC rated range and 90–264VAC input range when reviewing this model. The PDF’s explanatory note also includes a 200–240VAC example; it does not match the MD200PC5 values in the main and input tables.
For an existing LED cabinet, compare the supply’s mounting points, terminal positions and cooling path before replacement. The environmental table lists 10–50% operating relative humidity and asks that high-humidity requirements be specified at ordering.
Frequently asked questions
What voltage and current does the MD200PC5 provide?
The MD200PC5 is specified for 5V DC output, a 0–40A output current range and 200W output power. Check the LED module voltage and required load before connecting it.
Does the MD200PC5 accept 110V and 220V AC?
Yes. Both are within the 100–240VAC rated input range shown in its main and input specifications. The input table also lists a 90–264VAC range and 47–63Hz input frequency.
Under what conditions is the efficiency at least 88%?
The specification gives ≥88% at 220VAC, full load and room temperature. This condition-specific value should not be treated as a guarantee at every input voltage or load.
What cooling and environment does it require?
The PDF lists ventilation/self-cooling, −30 to +60°C operating temperature and 10–50% operating relative humidity. It asks buyers to specify high-humidity requirements when ordering. Check airflow and mounting conditions in the intended cabinet.
What should I check when replacing an LED cabinet power supply?
Compare the MD200PC5 model, AC input, 5V DC output, required current, mounting dimensions and terminal arrangement. A matching 5V/40A rating alone does not verify mechanical or wiring compatibility.
