Only in one review: Current 4 A (АД-12-4A); Power 4.8 W (24 V 200 mA power supply); Test current 4.5 A (АД-12-4A); Efficiency 85 % (АД-12-4A); No load 0.45 W (АД-12-4A); Protection 4.9 A (АД-12-4A); Temperature rise 111 °C (АД-12-4A); Price 2.72 $ (24 V 200 mA power supply).

АД-12-4A: It has power headroom and low ripple, but an electrical-safety issue remains.

24 V 200 mA power supply: It meets its rated specifications, but has little power headroom and lacks a fuse.
