Selection and Installation
Check the cabinet’s module voltage, peak current, terminals and mounting arrangement. Follow the input and temperature derating curves in the PDF. Its environmental notes require an auxiliary baseplate of at least 300 × 300 × 5.0mm for high-temperature full-load aging tests; review the intended thermal installation before loading the supply.
Frequently Asked Questions
1. What is the MDK300PC5 output rating?
The manufacturer specification lists 300W, +5.0Vdc output and a 0–60A output current range.
2. What is the difference between rated input and input range?
For this model, the electrical table lists 100–240Vac rated input and a 90–264Vac input voltage range. Use the derating curve when assessing available output.
3. Can MDK300PC5 replace MDK300SH5?
Compare both complete specifications first. Their input ratings differ, and matching DC output does not confirm connector, mounting or thermal compatibility.
4. Where can I find the MDK300PC5 drawing?
The retained PDF below includes dimensions, mounting information and derating curves.
