Thermal and replacement requirements
For high-temperature, full-load burn-in, the specification requires an auxiliary heat-spreading base plate of at least 300 × 300 × 5.0 mm. Maintain airflow and apply the manufacturer’s derating curves; the operating-temperature range alone does not promise full output under every installation condition.
Use the original PDF for terminal assignments and mounting-hole positions. Match the MDK300PC5 nameplate, input voltage, DC polarity and required load when replacing an existing LED wall supply.
