Input Specifications
* At full load.
Line Harmonics
Active power-factor correction circuitry ensures that this power supply meets the requirements of IEC1000-3-2 with
up to four power supplies connected in parallel and operating at full load.
Efficiency and Power Factor vs. Input Voltage at Full Load
Notes:
When using this table to calculate line cord requirements, allow, at a minimum, an extra 3% for variations between units.
Actual measured results will depend upon the harmonic content of the input voltage waveform.
