Review conclusionWith reservationsRecommended

Only in one review: In test 130 W (100-watt power supply); Under load 11.92 V (100-watt power supply); No load 0.2 W (Track power supply, 48 V 2.1 A, 100 W).

Track power supply, 48 V 2.1 A, 100 W: A compact supply with good power and moderate heating, but its protection-trip current is much too high.

100-watt power supply: A good supply: it handled 11 A at 230 V, with normal temperatures and an output filter.

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.
