Review conclusionWith reservationsRecommended

Only in one review: Test current 4.1 A (Sanmim GPN30E-15); Efficiency 82 % (Sanmim GPN30E-15); No load 0.4 W (АД-12-1A); Price 6.76 $ (Sanmim GPN30E-15).

АД-12-1A: This compact supply holds 1 A, but its output diode overheats at maximum load.

Sanmim GPN30E-15: It handles a twofold overload steadily with moderate heating; its main drawback is the cheap terminal blocks.
