Review conclusion	With reservations	—

Only in one review: Under load 12.33 V (АД-12-3A); No load 0.45 W (АД-12-3A).

АД-12-3A: Low ripple and good cooling; it can run continuously above its rating, but the author notes an electrical-safety issue.

24 V 2.5 A power supply: Well-built and stable, but after warming up it cannot sustain the rated 2.5 A because of its protection threshold.
