Review conclusionWith reservationsRecommended

Only in one review: Under load 12.034 V (Meanwell LRS-150-12); Ripple 400 mV (12 V 150 W power supply); Efficiency 89 % (12 V 150 W power supply).

12 V 150 W power supply: Efficiency is about 89%, but the snubber and power transistors overheat at 12 A.

Meanwell LRS-150-12: The PSU has excellent filtering and voltage stability with no heating concerns, but is poorly suited to conversion into a UPS.
