Follow the PDF input and temperature derating curves, including the note requiring an auxiliary heatsink beneath this small housing. Confirm the full model identifier rather than selecting by output wattage alone.
Frequently Asked Questions
1. What is the MDK200PC5 output rating?
The manufacturer specification lists 200W, +5.0Vdc output and a 0–40A current range, with load selection subject to the input derating curve.
2. Is its rated input 100–200Vac or 100–240Vac?
The retained manufacturer PDF lists 100–240Vac rated input and 90–264Vac input range. The new table follows that model-specific document.
3. What size is MDK200PC5?
The PDF lists 165 × 55 × 26mm with ±1.0mm dimensional tolerance. Check mounting holes and wiring clearance separately.
4. Does MDK200PC5 need additional heat dissipation?
The PDF environmental notes require an auxiliary heatsink beneath the supply. Follow its thermal mounting instructions and derating curves.
