Review conclusionWith reservationsRecommended

Only in one review: Voltage 12 V (PLF12A-12); No load 0.4 W (AD-12-1A); Price 4.24 $ (PLF12A-12).

AD-12-1A: The output diode overheats at 1 A, though the author considers it adequate at lower loads.

PLF12A-12: The compact supply holds its rated output well, with low ripple and overload, short-circuit, and overheat protection.

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.
