Review conclusionWith reservationsWith reservations

Only in one review: In test 77 W (PS-220/24-1,5); Efficiency 84 % (Sealed 36 W 3 A); No load 9 W (PS-220/24-1,5); Protection 3.4 A (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.

PS-220/24-1,5: A robust industrial PSU exceeds its rated power, but draws heavily at idle and has large low-frequency ripple.

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.
