2.1.4.8 AC Line Fast Transient (EFT) Specification
The power supply meets the EN 61000-4-5 directive and any additional requirements in
IEC1000-4-5:1995 and the Level 3 requirements for surge-withstand capability, with the
following conditions and exception:
These input transients do not cause any out-of-regulation conditions, such as overshoot
and undershoot, nor do they cause any nuisance trips of any of the power supply
protection circuits
The power supply meets surge-withstand test conditions under maximum and minimum
DC-output load conditions.
2.1.4.9 AC Line Leakage Current
The maximum leakage current to ground for each power supply is 3.5mA when tested at
240VAC.
2.1.5 DC Output Specifications
2.1.5.1 Grounding
The ground of the pins of the power supply output connector provides the power return path.
The output connector ground pins are connected to safety ground (power supply enclosure).
2.1.5.2 Standby Output
The 5VSB output is present when an AC input greater than the power supply turn-on voltage is
applied.
