Only in one review: Test current 15 A (24 V 16.7 A 400 W power supply with 0–10 V control); Under load 23.408 V (24 V 16.7 A 400 W power supply with 0–10 V control); Efficiency 86 % (24 V 16.7 A 400 W power supply with 0–10 V control); Temperature rise 117 °C (24 V 16.7 A 400 W power supply with 0–10 V control).

24 V 16.7 A 400 W power supply with 0–10 V control: Well built with decent components, but continuous power is about 200–240 W, not 400 W; control can damage loads with input capacitors.

48 V 8.3 A power supply: Ripple meets the specification, but continuous output is only about 200 W; 400 W is available briefly.
