350W Power Subsystem Intel

Server System R1304BTSSFAN/R1304BTLSFAN/R1304BTLSHBN TPS

22 Revision 2.0

Intel order number G17455-004

Table 21. AC Input Rating

Parameter Min Rated Max Max Input AC Current

Line Voltage (110) 90Vrms 100-127 Vrms 140Vrms 6 Arms1

Line Voltage (220) 180Vrms 200-240 Vrms 264Vrms 3 Arms2

Frequency 47 Hz 50/60Hz 63 Hz

Notes:

1. Maximum input current at low input voltage range should be measured at 90 VAC at max load.

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

4.7 Output Power/Currents

The following tables define two power and current ratings for this 350-W power supply. The

combined output power of all outputs should not exceed the rated output power. The power

supply must meet both static and dynamic voltage regulation requirements for the minimum

loading conditions.

Table 22. Load Ratings

Voltage Minimum Maximum

Output Power

+3.3 V 0.1 A 10 A 33W

+5 V 0.1 A 16 A 80W

+12 V1 0.75 A 18 A 216W

+12 V2 0.75 A 18 A 216W

-12 V 0 A 0.5 A 6W

+5 VSB 0.05 A 2.5 A 12.5W

Notes:

1. The total current of +12V1/2 will not exceed 28A.

2. The total output for this PSU is 350W.

3. The total output of +3.3V&+5V will not exceed 100W

4.8 Protection Circuits

Protection circuits inside the power supply should cause only the power supply’s main outputs

to shut down. If the power supply latches off due to a protection circuit tripping, an AC cycle

OFF for 15sec min (with +5VSB/0.1A) and a PSON# cycle HIGH for 1sec shall be able to reset

the power supply.

4.8.1 Over Current Protection (OCP)

Each output shall have individual OCP protection circuits. The PSU shall shutdown and latch off

after an over current condition occurs. Whereas OCP of +5VSB shall turn the power supply into

“hiccup mode” until the OCP condition removed. The values are measured at the PSU harness

connectors and shall not be damaged from repeated power cycling in this condition. There shall

be current sensors and limit circuits to shut down the entire power supply if the limit is

exceeded. The limits are listed below.
