Only in one review: Ripple 200 mV (MN-400-12); No load 1.2 W (48 V, 8.3 A, 400 W (standard model)).

48 V, 8.3 A, 400 W (standard model): A well-made supply with good test results, but the author considers about 250 W its realistic continuous power.

MN-400-12: A well-built PSU with low ripple, but it delivers 200–250 W instead of the claimed 400 W.
