Review conclusionWith reservationsRecommended

Only in one review: Current 5 A (BP120B-D9-24C); Ripple 80 mV (BP120B-D9-24C); No load 3.5 W (BP120B-D9-24C); Price 110 $ (BP120B-D9-24C).

BP120B-D9-24C: It delivers its rated power and holds voltage accurately, but runs hot and is expensive.

MeanWell SDR-120-24: The PSU passed the tests; the author praised its build and protections but noted that the transformer runs quite hot.
