Review conclusionWith reservationsWith reservations

Only in one review: Ripple 70 mV (PTA-150W-12V).

12 V 150 W power supply: A decent supply with accurately set protection, though the transformer runs hot and the input capacitor is undersized.

PTA-150W-12V: A budget PSU with acceptable temperature and efficiency, but high low-frequency ripple and insufficient input capacitance.

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.
