Only in one review: Ripple 100 mV (24 V 16.7 A 400 W power supply with 0–10 V control); 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.

24 V 16.7 A 400 W power supply with 0–10 V control: Well built, but delivers about 200–240 W continuously, well below the claimed 400 W.
