Intel® Server System S7000FC4UR TPS 1570W Power Supply
Revision 1.0

10.2.4 OverCurrent Protection
Over-current is a fault condition defined as a 10A/s current ramp starting from full load applied
to the output under test. A fault on any output will cause the rest of the outputs to latch off. (See
note 4.)
Table 25. Over-Current Protection Limits
Output Level Input Voltage Minimum
2,4
Maximum
2,4
+3.3V standby
1,3,4,
7 Amps 10 Amps
+12V 90 – 140 VAC 115 Amps 132 Amps
+12V 180 – 264 VAC 151 Amps 173 Amps
Notes:
1. Output is Level III SELV and non-energy hazard complaint
2. The above current limits will be satisfied throughout the entire operating temperature range
3. A fault on any output other than +3.3V standby will not cause the +3.3V standby to turn off. A fault on
+3.3V standby will cause the other outputs to turn off.
4. Dynamic loading must not cause a false over current when two supplies are in parallel.
5. The +3.3V standby output will not latch off. It must return to normal operation once the fault is removed.
Current foldback method is preferred.
10.2.5 Short Circuit Protection
A short circuit, which is defined as an impedance of 0.1 ohms or less, applied to any output
during start-up or while running will not cause any damage to the power supply (connectors,
components, PCB traces, etcetera).
When the +3.3VSB is shorted the output may go into “hiccup mode.” When the +3.3VSB
attempts to restart, the maximum peak current from the output must be less than 8.0A. The
maximum average current, taking into account the “hiccup” duty cycle, must be less than 4.0A.
10.2.6 Reset After Shutdown
If the power supply latches into a shutdown state due to a fault condition on any output, the
power supply will return to normal operation only after the fault has been removed and the
power supply has been power-cycled. Power cycling is defined as either:
Removing AC input power, waiting for +3.3V standby to drop below 1.0V, then
reapplying AC power. (The time it takes for +3.3V standby to drop below 1.0V must not
exceed 15 seconds.)
Cycling the state of PS_ON from on to off to on. (The minimum cycle time will be 1mS.)
