Review conclusionWith reservationsWith reservations

Only in one review: Current 3 A (Sealed 36 W 3 A); Efficiency 84 % (Sealed 36 W 3 A); Protection 3.4 A (Sealed 36 W 3 A); Temperature rise 70 °C (Sealed 36 W 3 A).

Sealed 36 W 3 A: Protection is set correctly and overheating is not an issue, but ripple is high—up to 700–800 mV at low frequency.

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.
