Only in one review: Test current 7 A (DC-DC converter board, 0–30 V, 0–8 A); Ripple 150 mV (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 board, 0–30 V, 0–8 A: A capable board with useful features, though using a ready-made power supply is simpler.
