2.2.2.8
AC Line Isolation Requirements
The power supply meets all safety agency requirements for dielectric strength. Transformers'
isolation between primary and secondary windings complies with the 3000Vac (4242Vdc)
dielectric strength criteria. In addition, the insulation system complies with reinforced insulation
per safety standard IEC 950. Separation between the primary and secondary circuits, and
primary to ground circuits, complies with the IEC 950 spacing requirements.
2.2.2.9
AC Line Leakage Current
The maximum leakage current to ground for each power supply is 3.5mA when tested at
240VAC.
2.2.2.10
AC Line Fuse
The power supply has a 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 inrush
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.
2.2.2.11
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.
2.2.3
Efficiency
The following table provides the required minimum efficiency level at various loading conditions.
These are provided at three different load levels: 100%, 50% and 20%. Efficiency is tested over
an AC input voltage range of 115VAC to 220VAC.
