Step load changes up to 85%@min. 10% load condition(+12V) and 35% (+3.3V and +5V) of full load.
-
* Other loads remain constant within the rating.
DC Output Voltage Hold-up Time
The power supply will maintain outputs in regulation per section 2.2.1 despite a loss of input power at the nominal range of AC input and at 80% of maximum continuous output load as applicable for a minimum of 12 msec.
Timing / Housekeeping / control
PWR_OK (Power Good Signal)
PWR_OK is a “power good” signal. It will be asserted high by the power supply to indicate that the +5V output is above the under voltage threshold listed in Table 2. of Section 2.2. PWR_OK will be de-asserted to a low state when +5V output voltage falls below under voltage threshold, or when AC power has been removed for a time sufficiently such that power supply operation cannot work normally. The electrical and timing characteristics of the PWR_OK signal are given in Table 10. and in figure 1.
Table 10. PWR_OK Signal Characteristics
PS_ON (DC Soft Start)
PS_ON# is an active-low, TTL-compatible signal that allows a motherboard to remotely control the power supply in conjunction with features such as soft on/off, Wake on LAN*, or wake-on-modem. When PS_ON# is pulled to TTL low, the power supply should turn on the four main DC output rails: +12 VDC, +5 VDC, +3.3 VDC, and -12 VDC. When PS_ON# is pulled to TTL high or open-circuited, the DC output rails should not deliver current and should be held at zero potential with respect to ground. PS_ON# has no effect on the +5VSB output, which is always enabled whenever the AC power is present. Table 11 lists PS_ON signal characteristics.
Table 11. PS_ON Signal Characteristics
+5Vsb (Standby Voltage Output)
+5Vsb is a standby voltage output that is active whenever the AC power is present. It provides a power source for circuits that must remain operational when the four main DC output rails are in a disabled state. Example uses include soft power control, Wake on LAN, wake on modem, intrusion detection, or suspend state activities. There is over current protection on the +5Vsb output to ensure the power supply will not be damaged if external circuits draw more current than the supply can provide.
Power-on Time
The power-on time is defined as the time from when PS_ON is pulled low to when the12V1, +5V, and +3.3V output are within the regulation ranges specified in Section 2.2.1. The power-on time will be less than 150ms (T1 <150 ms). +5Vsb has a power on time of one second max. after the valid AC Voltages applied.
Rise Time
The output voltage rise from ≤ 10% of nominal to within the regulation ranges specified in section 2.2.1 within 0.2 ms to 20 ms (0.2 ms ≤ T2 ≤ 20 ms)
Power Sequencing
The +12V1 and +5V output levels are equal to or greater than the +3.3V output at all times during power-up and normal operation. The time between the +12V1 or +5V output reaching its minimum in-regulation level and +3.3V reaching its minimum in-regulation level is ≤ 20 msec.
Overshoot at Turn-on / Turn-off
The output voltage overshoot upon the application or removal of the input voltage, or the assertion / de-assertion of PS_ON will be less than 10% above the nominal voltage.
Reset after Shutdown
If the power supply latches into a shutdown state because of a fault condition on its outputs, the power supply can return to normal operation only after the fault condition has been removed and the PS_ON has been cycled OFF/ON with a minimum OFF time of 1 second.
+5Vsb at AC Power-down
After AC power is removed, the +5Vsb standby voltage output will remain at its steady state value for the minimum hold-up time specified in Section 2.2.6 until the output begins to decrease in voltage. The decrease can be monotonic in nature, dropping to 0.0V. There are no other perturbations of this voltage at or following removal of AC power.
Output Protection
Over Voltage Protection
The power supply can provide latch-mode over voltage protection as defined in Table 12.
Table 12. Over Voltage Protection
Under Voltage Protection
The power supply can provide latch-mode Under voltage protection as defined in Table 13.
Table 13. Under voltage Protection
Over Current Protection
The power supply can provide Over Current Protection as defined in Table 14.
Table 14. Over Current Protection
Short-circuit Protection
The power supply will shut down and latch off for shorting the +12V, +5V, +3.3V, and -12V rails to return or any other rails. Shorts between main output rails and +5Vsb will not cause any damage to power supply. +5Vsb can be capable of being shorted indefinitely, but when the short is removed, the power supply will recover automatically or by cycling PS_ON. The power supply can be capable of withstanding a continuous short circuit to the output without damage or overstress to the unit under the input conditions specified in section 2.1.
Over Power Protection
Fold back at 110%~150% over peak load
OVER TEMPERATURE PROTECTION
Protection temperature is 50°C to 70°C at 115V and full load
No-load Operation
No damage or hazardous condition will occur with all the DC output connectors disconnected from the load. The power supply may latch into the shutdown state.
