Review conclusion—With reservations

Only in one review: Current 12.5 A (12 V 150 W power supply); Ripple 400 mV (12 V 150 W power supply).

12 V 150 W power supply: The 150 W model has about 89% efficiency, but its snubber and power transistors overheat under load.

12 V 150 W power supply: A decent supply with accurately set protection, though the transformer runs hot and the input capacitor is undersized.

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.
