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. 
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. 
2.6 AC Surge Voltages   
The power supply shall be tested and be compliant with the requirements of IEC61000-4-5 Level 3 criteria for 
surge withstand capability, with the following conditions and exceptions. The test equipment and calibrated 
waveforms shall comply with the requirements of IEC61000-4-5 for open circuit voltage and short circuit 
current. 
■  These input transients must not cause any out of regulation conditions, such as overshoot and undershoot, 
nor must it cause any nuisance trips of the power supply protection circuits. 
■  The surge-withstand test must not produce damage to the power supply. 
■  The power supply must meet surge-withstand test condition under maximum and minimum DC output load 
conditions. 
2.7 Surge Immunity, IEC61000-4-5   
The peak value of the unidirectional surge waveform shall be 2KV for common mode and 1KV for differential 
mode of transient surge injection. No unsafe operation or no user noticeable degradation is allowed under any 
condition. Automatic or manual recovery is allowed for other conditions. 
2.8 Electrical Fast Transient / Burst, IEC61000-4-4   
No unsafe operation allowed under any condition . No user noticeable performance degradation up to 1KV is 
allowed. Automatic or manual recovery is allowed for other conditions. 
2.9 Electrical Discharge, IEC61000-4-2   
In addition to IEC61000-4-2, the following ESD tests should be conducted. Each surface area of the unit under 
test should be subjected to twenty (20) successive static discharges, at each of the follow voltages: 2KV, 3KV, 
4KV, 5KV, 6KV and 8KV.   
All power supply outputs shall continue to operate within the parameters of this specification, without glitches 
or interruption, while the power is operating as defined and subjected to 2kV through 10kV ESD pulses. The 
direct ESD event shall not cause any out of regulation conditions such as overshoot or undershoot. The power 
supply shall withstand these shocks without nuisance trips of the Over-Voltage Protection, Over-Current 
Protection, or the remote +5VDC, +12VDC shutdown circuitry.
