4.3. HOLD-UP TIME (@Typical load of Table 1.) 115V / 60Hz : 17 m sec. minimum. 230V / 50Hz : 17 m sec. minimum. The output voltage will remain within specification, in the event that the input power is removed or interrupted, for the duration of one cycle of the input frequency. The interruption may occur at any point in the AC voltage cycle. The power good signal shall remain high during this test. 4.4. OUTPUT RISE TIME (10% TO 95% OF FINAL OUTPUT VALUE, @FULL LOAD) 115V-rms or 230V-rms + 3.
4.7. SHORT CIRCUIT PROTECTION Output short circuit is defined to be a short circuit load of less than 0.1 ohm. In the event of an output short circuit condition on +3.3V, +5V, +12V or –12V output, the power supply will shutdown and latch off without damage to the power supply.The power supply shall return to normal operation after the short circuit has been removed and the power switch has been turned off for no more than 2 seconds. 4.8. POWER SIGNAL POWER GOOD @115/230V,FULL LOAD 100 –500m sec.
4.9. The main power supply shall be off when the PS_ON pin is floating (open collector). The ON/STBY pin of P1 must remain off state for 5 Sec (maximum) prior to switching to the ON state 5. FAN NOISE REQUIREMENTS 5.1.The subject power supply is cooled by a self-contained, 80mm×15mm, 12VDC fan. 6. ENVIRONMENTAL REQUIREMENTS The power supply will be compliant with each item in this specification for the following Environmental conditions. 6.1. TEMPERATURE RANGE Operating +10 to +50 deg.
6.4. GROUND LEAKAGE CURRENT The power supply ground leakage current shall be less than 3.5 mA. 6.5. RELIABILITY The power supply reliability, when calculated by MIL-HDBK-217;latest revision, are exceed 100,000 hours with all output at Typical load and an ambient temperature of 25℃. 6.6.
