0–30 V, 0–7.5 A converter board or DC-DC converter with display

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: Ripple: DC-DC converter with display (60 mV vs. 150); Temperature rise: 0–30 V, 0–7.5 A converter board (75 °C vs. 110.2).

Only in one review: Test current 3 A (DC-DC converter with display); Price 5 $ (0–30 V, 0–7.5 A converter board).

0–30 V, 0–7.5 A converter board: A compact power board with good circuitry, but ripple exceeds the specification and the shunt gets hot.

DC-DC converter with display: The compact converter is usable up to about 2 A, but heats up considerably at higher currents and may fail with excessive input voltage.
