Technical Product Specification

Intel® Workstation System SC5650SCWS TPS Power Sub-system

Revision 1.2

Intel order number: E81822-002

4.1.5.3.1 Electrostatic Discharge Susceptibility

The power supply complies with the limits defined in EN 55024: 1998 using the IEC 61000-4-

2:1995 test standard and performance criteria B defined in Annex B of CISPR 24.

4.1.5.3.2 Fast Transient/Burst

The power supply complies with the limits defined in EN55024: 1998 using the IEC 61000-4-

4:1995 test standard and performance criteria B defined in Annex B of CISPR 24.

4.1.5.3.3 Radiated Immunity

The power supply complies with the limits defined in EN55024: 1998 using the IEC 61000-4-

3:1995 test standard and performance criteria A defined in Annex B of CISPR 24.

4.1.5.3.4 Surge Immunity

The power supply is tested with the system for immunity to AC Ringwave and AC Unidirectional

wave, both up to 2kV, per EN 55024:1998, EN 61000-4-5:1995 and ANSI C62.45: 1992.

The pass criteria include: no unsafe operation is allowed under any condition; all power supply

output voltage levels must stay within proper specification levels; no change in operating state

or loss of data during and after the test profile; no component damage under any condition.

The power supply complies with the limits defined in EN55024: 1998 using the IEC 61000-4-

5:1995 test standard and performance criteria B defined in Annex B of CISPR 24.

4.1.5.4 AC Line Fast Transient (EFT) Specification

The power supply meets the EN61000-4-5 directive and any additional requirements in

IEC1000-4-5: 1995 and the Level 3 requirements for surge-withstand capability, with the

following conditions and exceptions:

 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 surge-withstand test must not produce damage to the power supply.

 The supply meets surge-withstand conditions under maximum and minimum DC-output

load conditions.
