2.4.5.9 AC Line Leakage Current
The maximum leakage current to ground for each power supply is 3.5mA when tested at
240VAC.
2.4.5.10 AC Line Fuse
The power supply has one line fused in the single line fuse on the Line (Hot) wire of the AC
input. The line fusing is acceptable for all safety agency requirements. The input fuse is a slow
blow type. AC in-rush current does not cause the AC line fuse to blow under any conditions. All
protection circuits in the power supply do not cause the AC fuse to blow unless a component in
the power supply has failed. This includes DC output load short conditions.
2.4.5.11 Power Factor Correction
The power supply incorporates a power factor correction circuit.
The power supply is tested as described in EN 61000-3-2: Electromagnetic Compatibility (EMC
Part 3: Limits – Section 2: “Limits for harmonic current emissions,” and meets the harmonic
current emissions limits specified for ITE equipment.
The power supply is tested as described in JEIDA MITI Guideline for Suppression of High
Harmonics in Appliances and General-Use Equipment, and meets the harmonic current
emissions limits specified for ITE equipment.
2.4.5.12 Efficiency
The following table provides the required minimum efficiency level at various loading conditions.
These efficiency levels are provided at three different load levels: 100%, 50% and 20%.
Efficiency is tested over an AC input voltage range of 115VAC to 220VAC.
