3.6.7 Ac Line 5 Vsb Holdup; Ac Line Leakage Current; Power Factor Correction; Dc Output Specification - Intel SR1625UR Technical Product Specification

Intel® Server System SR1625UR TPS
The power supply must meet the AC inrush current 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 , (includes hot and cold inrush). It is acceptable that AC line inrush current may reach up to
op
60 A peak for up to 1 msec.

3.6.7 AC Line 5 VSB Holdup

The 5 VSB output voltage stays in regulation under its full load (static or dynamic) during an AC
dropout of 70 ms minimum (=5 VSB holdup time) regardless of whether the power supply is in
ON or OFF state (PSON asserted or de-asserted).
3.6.8

AC Line Leakage Current

The maximum leakage current to ground for each power supply is not more than 3.5 mA when
tested at 240 VAC.
3.6.9

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.

Output Power/Currents

The following table defines the power requirements for the power supply module.
Notes:
1. The two 40-mm fans are powered from 5 VSB when in standby mode.
2. +5 VSB provides power to the two 40-mm fans cooling the power supplies in standby mode. 1 A of 5 VSB is
reserved for powering the fan in standby mode.
3. Vbias maximum load is based on PDB circuits. This output is optional depending on whether the PDB
requires a higher voltage to power its 240 VA circuits.
4. Peak current time duration does not exceed 12 sec.
