ParameterMinTypicalMaxUnitRemarks
Input over-voltage760810Vdc
Over-voltage recovery750800Vdc
Input low-voltage170190Vdc
Low-voltage recovery180200Vdc
Output over-voltage3133VdcAuto recovery, output flow backwards 50Vdc without damage.
Output low-voltage18.019.0VdcAuto recovery
Over-current1. 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 55A.
Over temperatureT>85°C, output derates linearly. T>95°C, output shut down. T<80°C,output auto recovers.
Output short-circuitAuto recovery when fault removed
Input reversedNo 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.
