Review conclusionWith reservationsWith reservations

Only in one review: Efficiency 89 % (12 V 100 W power supply).

12 V 100 W power supply: Efficiency is about 89%, but the output rectifier transistor overheats under heavy load.

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.

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.
