Only in one review: Voltage 30 V (0–30 V, 0–7.5 A converter board); Current 7.5 A (0–30 V, 0–7.5 A converter board); Test current 6 A (35 V 5 A Linear Adjustable Power Supply Kit); Under load 41 V (35 V 5 A Linear Adjustable Power Supply Kit); Weight 175 g (35 V 5 A Linear Adjustable Power Supply Kit).
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.
35 V 5 A Linear Adjustable Power Supply Kit: The kit assembled easily and delivered 41 V at 5 A, but ripple is notable and some components need improvement.
