Efficiency figures and installation
The original product text and the PDF overview state efficiency of 86% or above. Section 5.1.4 of the same V1.0 document instead gives ≥89% at 220 Vac, full load and room temperature. These source figures differ; confirm the applicable value for the supplied revision rather than treating one as a universal guarantee.
Check the nameplate, DC polarity, load current and terminal layout before connection. Keep the ventilation openings clear and use the manufacturer’s mounting and temperature-derating information for the actual cabinet conditions.

Frequently asked questions
What is the MDH200PC5 output?
The specification lists +5 V DC, 0–40 A and 200 W, with a 4.95–5.05 Vdc output-voltage range.
What are the MDH200PC5 dimensions?
The linked V1.0 mechanical section gives 142 × 59 × 30 mm. Refer to its drawing for mounting-hole positions and connector clearance.
Does it accept 100–240 V mains?
Yes. The documented rated input is 100–240 Vac and the operating range is 90–264 Vac at 47–63 Hz.
Is the stated efficiency 86% or 89%?
The overview states 86% or above, while the electrical table gives ≥89% at 220 Vac, full load and room temperature. Confirm the supplied revision because the document contains both figures.
Where can I find the original specification and photos?
All four original product images and the original manufacturer PDF download remain on this page.
