Only in one review: Voltage 80 V (RK8009); Current 9 A (RK8009); Power 720 W (RK8009); Under load 81 V (RK8009); Efficiency 98.9 % (RK8009); No load 1.2 W (G1208-20013120A).

RK8009: The converter showed low ripple, high efficiency and good thermal performance; its main drawback is limited input-voltage headroom.

G1208-20013120A: The author liked this compact dual-channel converter for its stability, power, decent efficiency, and protections.
