Ac Line Isolation Requirements; Ac Line Leakage Current; Ac Line Fuse; Power Factor Correction - Intel SR1530AHNA Technical Product Specification

Power Sub-System
be no more than the specified maximum input current. AC line inrush current may exceed 55 A
peak during hot start at 45°C. The peak inrush current shall be less than the ratings of its
critical components (including input fuse, bulk rectifiers, and surge limiting device).
The power supply must meet the inrush requirements for any rated AC voltage, during turn on at
any phase of AC voltage, during a single cycle AC dropout condition as well as upon recovery
after AC dropout of any duration, and over the specified temperature range (T

AC Line Isolation Requirements

The power supply shall meet all safety agency requirements for dielectric strength. Additionally,
the power supply vendor must provide Intel with written confirmation of the dielectric withstand
test which includes: voltage level, duration of test and identification detailing how each power
supply is marked to indicate the dielectric withstand test had been completed successfully.
Transformers' isolation between primary and secondary windings must comply with the
3000Vac (4242Vdc) dielectric strength criteria. If the working voltage between primary and
secondary dictates a higher dielectric strength test voltage, the highest test voltage should be
used. In addition the insulation system must comply with reinforced insulation per safety
standard IEC 950. Separation between the primary and secondary circuits, and primary to
ground circuits, must comply with the IEC 950 spacing requirements.

AC Line Leakage Current

The maximum leakage current to ground for each power supply shall be 3.5 mA when tested at
240VAC.

2.17 AC Line Fuse

The power supply shall have one line fused in the single line fuse on the line (Hot) wire of the
AC input. The line fusing shall be acceptable for all safety agency requirements. The input fuse
shall be a slow blow type. AC inrush current shall not cause the AC line fuse to blow under any
conditions. All protection circuits in the power supply shall not cause the AC fuse to blow unless
a component in the power supply has failed. This includes DC output load short conditions.

2.18 Power Factor Correction

The power supply shall incorporate a Power Factor Correction circuit.
The power supply shall be tested as described in EN 61000-3-2: Electromagnetic Compatibility
(EMC) Part 3: Limits- Section 2: Limits for harmonic current emissions, and shall meet the
harmonic current emissions limits specified for ITE equipment.
The power supply shall be tested as described in JEIDA MITI Guideline for Suppression of High
Harmonics in Appliances and General-Use Equipment and shall meet the harmonic current
emissions limits specified for ITE equipment.

2.19 Efficiency

The power supply shall have a recommended efficiency of 70% at maximum load and over the
specified AC voltage.
