Review conclusionWith reservationsWith reservations

Only in one review: In test 250 W (S-240-12); Under load 47.9 V (48 V 5 A 240 W power supply); Efficiency 84 % (S-240-12); No load 4.2 W (S-240-12).

S-240-12: An average Chinese power supply with low ripple and stable voltage, but middling build quality and unknown components.

48 V 5 A 240 W power supply: The power supply performed very well in testing, but needs diode-mounting work and some component replacement or repositioning.

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.
