Technical Product Specification

Power Subsystem Intel® Server System SR2600UR TPS
22 Intel order number E45274-011 Revision 1.8
3.8 AC Input Requirements
The power supply module incorporates universal power input with active power factor correction,
which reduces line harmonics in accordance with the EN61000-3-2 and JEIDA
MITI standards.
3.8.1 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 only
at 230 VAC.

Notes:
1. Maximum input current at low input voltage range is measured at 90 VAC, at maximum load.
2. Maximum input current at high input voltage range is measured at 180 VAC, at maximum load.
3. This is not to be used for determining agency input current markings.
4. Maximum rated input current is measured at 100 VAC and 200 VAC.
Harmonic distortion of up to 10% of the rated AC input voltage must not cause the power
supply to go out of specified limits. The power supply powers off at or below 75 VAC ± 5 VAC.
The power supply starts up at or above 85 VAC ± 4 VAC. Application of an input voltage below
85 VAC does not cause damage to the power supply or blow a fuse.
