Review conclusionWith reservationsWith reservations

Only in one review: Current 16.5 A (HCF-200-12); In test 216 W (PTA-200W-12V); Test current 18 A (PTA-200W-12V); Efficiency 84 % (PTA-200W-12V); Protection 20.7 A (HCF-200-12).

PTA-200W-12V: This budget supply handles about 216 W, but its rectifier and choke get hot, and low-frequency ripple is high.

HCF-200-12: Generally performs well, but ripple and inductor and shunt heating drew some criticism.

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.
