HCA-60 or YS-U50SL

Two models side by side: measurements taken by the author in their reviews, and their conclusions. The better value in each row is highlighted.

In brief: Based on review measurements: Test current: HCA-60 (5 A vs. 3.1); Ripple: YS-U50SL (15 mV vs. 700); Efficiency: YS-U50SL (88 % vs. 84.5).

Review conclusionWith reservationsRecommended

Only in one review: Voltage 24 V (YS-U50SL); In test 75 W (YS-U50SL); No load 0.4 W (YS-U50SL); Temperature rise 115 °C (HCA-60); Price 7.99 $ (YS-U50SL).

HCA-60: Ripple is high, but temperatures are better than on the HCA-48; the author puts its practical output at about 50 W.

YS-U50SL: A compact PSU with low ripple and ample power headroom; the author liked it, though its thermal protection is set too high.

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.
