Review conclusionNot recommendedRecommended

Only in one review: In test 50 W (48 V 1 A power supply); Efficiency 85 % (QS-48-12); No load 0.55 W (QS-48-12); Temperature rise 115 °C (QS-48-12).

QS-48-12: It falls short of 48 W: the transformer overheats, and the author considers it closer to a 36 W model.

48 V 1 A power supply: The author liked it: it delivers about 25 W continuously and up to 45–50 W briefly.

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.
