1.4 Protection against

Parameter Min Typical Max Unit Remarks
Input over-voltage 430   460 Vdc  
Over-voltage recovery 420   450 Vdc  
Input low-voltage 220   240 Vdc  
Low-voltage recovery 230   250 Vdc  
Output over-voltage 31   33 Vdc Auto recovery, output flow backwards 50Vdc without damage.
Output low-voltage 18.0   19.0 Vdc Auto recovery
Over-current 1. If input voltage >250V, output current 110~136A, the unit is able to continuously operate full load for 6min, and then current limiting point drops to 110A. 2. When Input voltage drops from 250V to 200V, output current limit also linearly drops from 110A to 75A.
Over temperature T>85°C, output derates linearly. T>95°C, outputs shut down. T<80°C,output auto recovers.
Output short-circuit Auto recovery when fault removed
Input reversed No damage if reversed
Input energizing sequencing
  1. High voltage before control signal 2. Control signal before high voltage. 3.High voltage and control signal at the same time. Power supply works normally, no protection triggered on damage caused.
