Ratings disagree by 4 steps

The engine rates this unit higher than the imported list, usually because the list de-tiers units that lack independent testing while the engine records that as low confidence instead.

How the tier was reached

  1. MISSED

    Tier A - reference classspec 12.9

    • Primary conversion stage: Legacy primary topology (DF)

    • Efficiency certification: Bronze class efficiency
    • AC input range: Restricted 230V-only input
    • Too many warnings for this tier (2)
    • Too many failed criteria for this tier (2)
  2. MISSED

    Tier B - strong mainstreamspec 12.10

    • Primary conversion stage: Legacy primary topology (DF)
    • Too many failed criteria for this tier (1)
