In brief: Based on review measurements: Test current: RK8009 (9 A vs. 6).
Model RK8009 Riden · 2026 Read review → RK6006 RuiDeng · 2023 Read review → Test current, A 9 6 Under load, V 81 61 Review conclusion Recommended Recommended
Only in one review: Voltage 80 V (RK8009); Current 9 A (RK8009); Power 720 W (RK8009); Ripple 50 mV (RK8009); Efficiency 98.9 % (RK8009).
RK8009: The converter showed low ripple, high efficiency and good thermal performance; its main drawback is limited input-voltage headroom.
RK6006: The converter works well with the enclosure and PSU; ripple at 61 V and 6 A was 60 mV.
