250W Power Subsystem Intel

Server System R1304BTSSFAN/R1304BTLSFAN/R1304BTLSHBN TPS

10 Revision 2.0

Intel order number G17455-004

3. 250W Power Subsystem

The power subsystem of the server systems consists of a single, non-redundant 250-W power

supply with five outputs: 3.3 V, 5 V, 12 V, -12V and 5 VSB. The form factor fits into a 1U system

and provides a wire harness output to the system. An IEC connector is provided on the external

face for AC input to the power supply. The power supply provides one; non-redundant 40 mm

fan for self -cooling. The power supply fans also provide additional airflow for parts of

the system.

The power supply operates within the following voltage ranges and ratings:

Table 3. Input Voltage Range

PARAMETER MIN RATED MAX Max Input AC Current

Line Voltage (110) 90Vrms 100-127 Vrms 140Vrms 6 Arms

Line Voltage (220) 180Vrms 200-240 Vrms 264Vrms 3 Arms

Frequency 47 Hz 50/60Hz 63 Hz

Notes:

1. Maximum input current at low input voltage range shall be measured at 90Vac, at max load.

2. Maximum input current at high input voltage range shall be measured at 180VAC, at max load.

The power supply must operate within all specified limits over the following input voltage ranges

shown in the table. Harmonic distortion of up to 10% Total Harmonic Distortion (THD) must not

cause the power supply to go out of specified limits.

3.1 Mechanical Specifications

The 1U 250 W power supply is designed specifically for use in the Intel

Server Systems

R1304BTSSFAN and R1304BTLSFAN. The physical size of the power supply enclosure is

intended to accommodate power ranges from 250 W. The power supply size is 40 mm x 81.5

mm x 150 mm and has a wire harness for the DC outputs. The AC input plugs directly into the

external face of the power supply; refer to the following figure for more information.
