  An AC line dropout is defined as a drop in AC line voltage to 0VAC at any zero phase of the AC line for any length                                       
  of time. An AC line dropout shall not cause any tripping of control signals or protection circuits. If the AC line                                       
  dropout lasts longer than the specified maximum duration the power supply should recover and meet all turn                                                 
  on requirements.
