One output covers most single-board and repair work. The range is wide: a 30 V, 5 A linear supply weighs 10 lb or more and gives a clean, quiet output, while a switcher of the same size class delivers 300 W to 1,000 W for under $250 at the cost of more noise. Siglent’s linear supplies lead on noise, resolution and remote sense; the import switchers lead on watts per dollar but rarely publish a ripple figure.
