4.8. POWER SIGNAL
POWER GOOD @115/230V, FULL LOAD 100 –500mSec.
POWER FAIL @115/230V, FULL LOAD 1 mSec. minimum
Figure:
T1: Power-on time shall be less than 500 ms (T1 < 500 ms).
T2: Rise time : 0.1 ms to 20 ms (0.1 ms ≤ T2 ≤ 20 ms).
T3: Power-ok delay time: 100 ms < T3 < 500 ms
T4: Power-ok rise time: T4 ≦ 1 ms
T5 + T6: AC loss to PWR_OK hold-up time :T5 + T6 ≥ 17 ms
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, 12VDC fan.
6. ENVIRONMENTAL REQUIREMENTS
The power supply will be compliant with each item in this specification for the following
Environmental conditions.
