Review conclusionRecommendedWith reservations

Only in one review: Current 3 A (24 Volt 3 Amp power supply); In test 66.5 W (24 Volt 3 Amp power supply); Under load 17.7 V (24 Volt 3 Amp power supply).

SANMIM GPT70A-12: A well-built supply with good protection and low ripple, but comparatively low efficiency and higher heat.

24 Volt 3 Amp power supply: The supply is well built and protected, but its ratings are overstated; continuous power is about 50 W.

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.
