Review conclusionWith reservationsRecommended

Only in one review: Current 8.3 A (12 V 100 W power supply); In test 103 W (Mean Well HDR-100-12N).

12 V 100 W power supply: The board heated noticeably at 7 A in open air; the author thinks a potted enclosure may improve cooling.

Mean Well HDR-100-12N: The author liked its low ripple and good output power, but found an unsoldered capacitor.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
