Review conclusionWith reservationsRecommended

Only in one review: Under load 12.216 V (CTG-300W-12V); Ripple 300 mV (CTG-300W-12V); Temperature rise 105 °C (CTG-300W-12V).

CTG-300W-12V: It is effectively suited to about 230–250 W; the small input capacitor and higher ripple detract from it.

48 V power supply: After repair, the PSU works as an approximately 150 W supply, though it was originally rated for 300 W.

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.
