Only in one review: Efficiency 77 % (12 V 3 A power supply).

PS-220/24-1,5: A robust industrial PSU exceeds its rated power, but draws heavily at idle and has large low-frequency ripple.

12 V 3 A power supply: Above 2 A, the supply overheats and behaves erratically; it is unsuitable for continuous use.
