Typical characteristics

① With an AC input between 85 - 110VAC/277- 305VAC and a DC input

between 70 - 130VDC/400 - 430VDC, the output power must be

derated as per temperature derating curves;

② This product is suitable for applications using natural air cooling; for

applications in closed environment please consult factory or one of

our FAE.
