Only in one review: Current 2.1 A (48 V, 2.1 A, 100 W (standard model)); Efficiency 86 % (48 V, 2.1 A, 100 W (standard model)).

48 V, 2.1 A, 100 W (standard model): Well built and runs cool, but its protection limits practical continuous power to about 75 W.

FSA-12V 100W: It works reliably at about 60 W from either 115 V or 230 V input, with acceptable ripple and case temperature.
