Review conclusionWith reservationsRecommended

Only in one review: Voltage 12 V (12 V 200 W power supply); In test 208 W (Track power supply, 48 V, 200 W); Test current 21.5 A (12 V 200 W power supply); No load 0.6 W (Track power supply, 48 V, 200 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.

12 V 200 W power supply: Well designed, with low ripple and little heating; one output diode assembly runs hotter than desirable.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
