Only in one review: In test 20 W (HCF-36R).

Sealed 36 W 3 A: Protection is set correctly and overheating is not an issue, but ripple is high—up to 700–800 mV at low frequency.

HCF-36R: It delivers only about 18–20 W continuously and is suitable for low-power loads.

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.
