2. AC Input Specifications
2.1 AC Input Voltage, Frequency and Current ( Rating: 100V-240Vac, 47-63Hz, 14-7A )
The power supply must operate within all specified limits over the input voltage range in Table 1.
Harmonics distortion of up to 10% THD must not cause the power supply to go out of specified
limits.
Harmonics distortion of up to 10% THD must not cause the power supply to go out of specified
limits.
Table 1 – AC Input Voltage and Frequency
2-2 AC Inrush Current
The power supply must meets inrush requirements of any rated AC voltage, during turn on at
any phase of voltage, during a single cycle AC dropout condition, during repetitive On/Off
cycling of AC, and over the specified temperature range. The peak inrush current shall be less
than the rating of its critical components (including input fuse, bulk rectifiers, and surge limiting
device).
any phase of voltage, during a single cycle AC dropout condition, during repetitive On/Off
cycling of AC, and over the specified temperature range. The peak inrush current shall be less
than the rating of its critical components (including input fuse, bulk rectifiers, and surge limiting
device).
2.3 Input Power Factor Correction ( Active PFC)
The power factor at full load shall be 0.99 at nominal input voltage.
2.4 Input Current Harmonics
When the power supply is operated in 90-264Vac of Sec. 2.1, the input harmonic current drawn on
the power line shall not exceed the limits set by EN61000-3-2 class “D” standards. The power supply
shall incorporate universal power input with active power factor correction.
the power line shall not exceed the limits set by EN61000-3-2 class “D” standards. The power supply
shall incorporate universal power input with active power factor correction.
2.5 AC Line Dropout
An AC line dropout of 17mS or less shall not cause any tripping of control signals or protection
circuits.
If the AC dropout lasts longer than 17mS the power supply should recover and meet all turn on
requirements. The power supply shall meet the regulation requirement over all rated AC voltages,
frequencies, and output loading conditions. Any dropout of the AC line shall not cause damage
to the power supply. An AC line dropout is defined as a drop in AC line to 0VAC at any phase of
the AC line for any length of time.
