Only in one review: Ripple 400 mV (LS-400W-12V); 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.

LS-400W-12V: The 400 W model delivered 410 W, but ran hot above 32 A and its protection threshold was incorrectly set.
