Missing evidence

These criteria could not be resolved. They lower the confidence index rather than count against the unit.

  • Active power factor correction
  • Electrolytic capacitor temperature rating
  • Fan bearing type
  • Protection coverage
  • Over-current protection declared
  • Over-temperature protection declared
  • Measured electrical behaviour
  • +12V ripple
