Review conclusionRecommendedRecommended

Only in one review: Current 3 A (24 V 3 A power supply); Ripple 120 mV (12 V 72 W power supply); Price 7 $ (12 V 72 W power supply).

24 V 3 A power supply: It handles its rated 3 A well, with low ripple and moderate temperatures; the transformer heats up at 3.5 A.

12 V 72 W power supply: A well-built compact PSU, but it overheats during sustained 6 A operation without airflow.
