Only in one review: Voltage 48 V (48 V 4.1 A, 200 W power supply); Current 4.1 A (48 V 4.1 A, 200 W power supply); Test current 3.3 A (48 V 4.1 A, 200 W power supply); Protection 4.6 A (Track power supply, 48 V, 200 W).

48 V 4.1 A, 200 W power supply: Well built and handles 4.3 A, but the author puts its sustained power at about 150–160 W.

Track power supply, 48 V, 200 W: Delivers about 208 W and performs well, but has notable 100 Hz ripple and a 50 V output capacitor.
