Only in one review: Voltage 30 V (DC-DC converter board, 0–30 V, 0–8 A); Current 8 A (DC-DC converter board, 0–30 V, 0–8 A); Under load 41 V (35 V 5 A Linear Adjustable Power Supply Kit); Ripple 50 mV (35 V 5 A Linear Adjustable Power Supply Kit); Weight 175 g (35 V 5 A Linear Adjustable Power Supply Kit).

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.

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.
