HCF-48L or Dual-voltage power supply

Two models side by side: measurements taken by the author in their reviews, and their conclusions. The better value in each row is highlighted.

In brief: Based on review measurements: Test current: HCF-48L (4 A vs. 2.838); Temperature rise: Dual-voltage power supply (84 °C vs. 117).

Review conclusionNot recommendedWith reservations

Only in one review: Current 4 A (HCF-48L); Power 48 W (HCF-48L); In test 47 W (Dual-voltage power supply); Under load 14.6 V (Dual-voltage power supply); Ripple 400 mV (HCF-48L); Efficiency 83 % (HCF-48L); Protection 4.2 A (HCF-48L).

HCF-48L: It creates substantial interference, and sustained operation above about 3.5 A causes voltage drop and high temperatures.

Dual-voltage power supply: The PSU works, but its output voltages vary greatly; the author notes the missing inductor on the 12 V channel.

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.
