Rating and installation notes
The original web table showed 300 W, 0–60 A, a 160–264 input range with a DC unit, and ≤200 mVp-p ripple. Those entries conflict with the exact-model PDF. The specifications above follow the PDF’s 200 W, 0–40 A and ≤150 mVp-p ratings; confirm the supplied unit’s nameplate and revision before ordering or applying a load.
The −30 to +70°C range is subject to derating. It does not mean full output is available at every temperature. Install the specified auxiliary heat-spreading plate and use the manufacturer’s input-voltage and temperature curves. Check the available AC mains supply against the 200–240 Vac rated-input requirement.

Frequently asked questions
Is the MQ200PC5A a 200 W or 300 W supply?
The linked exact-model V1.0 PDF lists 200 W at 5 V DC with a 0–40 A current range. The original web table showed conflicting 300 W / 60 A figures. Verify the supplied unit’s nameplate before selecting it.
Can I power the MQ200PC5A from 110 V AC?
110 V is outside the documented input range. The PDF gives 200–240 Vac rated input and 176–264 Vac in its operating-input table.
What cooling does this slim power supply need?
The PDF specifies ventilation cooling with an auxiliary 200 × 200 × 3 mm heat-spreading plate beneath the supply. Follow its derating curves for the actual cabinet conditions.
How can I confirm price and the correct model?
Check the current product purchase options or request a quotation using MQ200PC5A and the required quantity. A nameplate photo helps confirm the revision and electrical ratings.
Where can I download the MQ200PC5A datasheet?
The original specification PDF is linked above and includes electrical data, mounting and connector details, and operating derating curves.
