Only in one review: Efficiency 87 % (Track power supply, 48 V 2.1 A, 100 W); No load 0.2 W (Track power supply, 48 V 2.1 A, 100 W).

Track power supply, 48 V 2.1 A, 100 W: A compact supply with good power and moderate heating, but its protection-trip current is much too high.

HCF-100-12: Ripple is about 30 mV, but the transformer gets quite hot at full load.
