Review conclusionWith reservationsWith reservations

Only in one review: Current 3 A (Desktop 36 W 3 A); Efficiency 84.5 % (Desktop 36 W 3 A); Protection 7 A (Desktop 36 W 3 A); Temperature rise 126 °C (Desktop 36 W 3 A).

Desktop 36 W 3 A: It delivers the rated 3 A, but with little thermal headroom; overcurrent protection is set too high and there is no thermal protection.

12 V 36 W power supply: The board is neat, but the varistor is before the fuse and ripple is high; it is suitable for undemanding loads.

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.
