SPECIFICATION
3.1.4. Inrush current :
After AC power is applied to the power supply in the stage of cold start, any peak inrush
current surge shall not damage the PSU and the input fuse shall not blow under any
conditions of DC output loading, temperature, input voltage including repeated, rapid
cycling of the power line.
Less than 100A at 115Vac and 25℃ ambient cold starting condition
Less than 100A at 240Vac and 25℃ ambient cold starting condition
3.1.5. Efficiency :
80% or greater at DC output with full loading and nominal AC input voltage range of
120V / 240Vac,60Hz / 50Hz.
3.1.6. Power factor :
Power factor of power supply shall meet 0.90 minimum @full load to be meet
EN61000-3-2
3.1.7. Power Line Harmonics requirement & PF :
The input current harmonics requirement shall be met with EN 61000-3-2 for power
harmonics models. The PF shall ≧0.9 at 240Vac. ≧0.95 at 100Vac for both 50/60Hz and
DC output with full load.
.
