Ripple voltage test circuit 2.4 Overshoot Any overshoot at turn on or turn off shall be less 10% of the norminal voltage value, all outputs shall be within the regulation limit of section 2.0 before issuing the power good signal of section 5.0. 2.
SST-ST75F-GS Voltage Over Current Limit (Iout limit) +12V 65A minimum; 95A maximum +5V 28A minimum; 45A maximum +3.3V 24A minimum; 40A maximum SST-ST85F-GS Voltage Over Current Limit (Iout limit) +12V 72A minimum; 105A maximum +5V 28A minimum; 45A maximum +3.3V 24A minimum; 40A maximum 3.2 Over Temperature Protection The power supply will be protected against over temperature conditions caused by loss of fan cooling or excessive ambient temperature.
ST85F-GS / ST75F-GS 3.6 Short circuit An output short circuit is defined as any output impedance of less than 0.1 ohms. The power supply shall shut down and latch off for shorting the +3.3 VDC,+5 VDC, or+12 VDC rails to return or any other rail. Shorts between main output rails and +5VSB shall not cause any damage to the power supply. The power supply shall either shut down and latch off or fold back for shorting the negative rails.
4.2 Hold up time When the power loss its input power, it shall maintain 17ms in regulation limit at normal input voltage. ( Tested at 75% of maximum load and 100-240VAC input ). 5. ENVIRONMENT 5.1 Operation O Temperature 0 to 40 C Relative Humidity 10 to 90%, non-condensing 5.2 Shipping and Storage O Temperature -20 to 60 C Relative Humidity 5 to 95%, non-condensing 5.3 Altitude Operating 10,000FT max Storage 50,000FT max 6. SAFETY 6.1 Underwriters Laboratory (UL) recognition.
ST85F-GS / ST75F-GS 7.10 EN55022 Class B Radio interference (CISPR 22). 7.11 FCC Part 15, Subpart J class B 115VAC operation. 8. MTBF 8.1 MTBF (mean time between failures) calculation The demonstrated MTBF shall be 100,000 hours of continuous operation at 25oC, at 80% load, and nominal line. The MTBF of the power supply be calculated in accordance with MIL-HDBK-217F. The DC FAN is not included. 9. MECHANICAL REQUIREMENTS 9.1 Physical Dimension 150 mm (W) × 86 mm (H) × 150mm (D) 9.
