Review conclusionRecommendedWith reservations

Only in one review: In test 77 W (PS-220/24-1,5); No load 9 W (PS-220/24-1,5); Protection 3.4 A (12 V 3 A power supply, adapter).

12 V 3 A power supply, adapter: After the revisions it runs without overheating even at 3.2 A, with acceptable ripple and electrical safety.

PS-220/24-1,5: A robust industrial PSU exceeds its rated power, but draws heavily at idle and has large low-frequency ripple.

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.
