Ratings disagree by 1 step

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)
    • Secondary rectification: Passive (Schottky) rectification
    • Minor rail regulation: Group-regulated minor rails
    • Efficiency certification: Bronze class efficiency
    • Too many failed criteria for this tier (3)
  2. MISSED

    Tier B - strong mainstreamspec 12.10

    • Primary conversion stage: Legacy primary topology (DF)
    • Secondary rectification: Passive (Schottky) rectification
    • Minor rail regulation: Group-regulated minor rails
    • Too many failed criteria for this tier (3)
  3. MISSED

    Tier C - adequatespec 12.11

    • Minor rail regulation: Group-regulated minor rails
    • Too many failed criteria for this tier (1)
  4. MISSED

    Tier D - basicspec 12.12

    • Minor rail regulation: Group-regulated minor rails
    • Secondary rectification: Passive (Schottky) rectification
  • Insufficient evidence, unknown platform or unsatisfactory architecture (spec 12.13)
  • Modifiers do not apply to E and F
