Output Details
Maximum peak total DC output power should not exceed 572W.
Peak power and current loading should be supported for a minimum of 1 second.
+3.3V, +5V and +12V DC output voltage should be within the cross loading range to meet regulation.
Ripple and Noise measuring with an oscilloscope with 20 MHz bandwidth in the cross loading range. Output should be bypassed at the connector with a 0.1uF ceramic disk capacitor and a 10uF electrolytic capacitor to simulate system load. The length of ground wire on probe should not be longer than 40mm, if a Non-differential type of scope was used.
2.1 Cross Regulation
The +5V & +3.3V combined load and +12VDC load shall remain within the defined limits in section 2.0 over cross load combinations.
Diagram Description: A line graph titled 'Cross Regulation' illustrates the relationship between +12V power output on the x-axis and the combined +5V & +3.3V power output on the y-axis. The graph shows a region where the power supply maintains regulation, with specific points indicating the boundaries of acceptable operation. For example, at 100W of +12V power, the combined +5V/+3.3V power is approximately 100W. As +12V power increases, the combined +5V/+3.3V power drops significantly, eventually reaching near zero at higher +12V loads.
2.2 Hold-Up Time
16ms (minimum). Test Condition: Full load. AC input 115V or 230V, 47Hz.
2.3 Load Transient Response (Step Load)
Step load changes up to 60% (12V) and 30% (3.3V and 5V) of full load, while other loads remain constant within the rating. The load waveform shall be a square wave with the slope of the rise and fall at 1.0A/usec and the frequency shall be from 50Hz to 10kHz. The DC output voltage will stay within regulation of ±5% during the step load changes.
2.4 Overshoot
Overshoot at turn on or turn off shall be less than 10% of the nominal output voltage.
2.5 Timing, Housekeeping and Control
A low active PS-ON (DC ON/OFF) input signal is equipped, which provides the interface to ENABLE or DISABLE the GROUP1 of DC output. This signal is electrically to interface with TTL, OPEN COLLECTOR, and the HARD SWITCH.
Diagram Description: A timing diagram shows the sequence of signals during power-on and power-off events. The top line represents AC Voltage (VAC). Below it, the PS_ON# signal is shown as a low-active signal that transitions from high to low to initiate power-on. The Outputs (+12 VDC, +5 VDC, +3.3 VDC) are shown to rise after a delay (T1: Power-on time). The PWR_OK signal, indicating power good status, rises after another delay (T3: PWR_OK delay) and has a specific rise time (T4: PWR_OK rise time). The diagram also illustrates the hold-up time (T5: AC loss to PWR_OK hold-up time) and the delay before PWR_OK becomes inactive upon DC loss (T6: PWR_OK inactive to DC loss delay).
| Signal Name | Maximum | Minimum |
|---|---|---|
| T1: PS_Power-on time | 500mS | |
| T2: Rise time from each main output | 20mS | 0.2mS |
| T3: PWR_ok delay | 500mS | 100mS |
| T4: PWR_ok rise time | 10mS | |
| T5: AC loss to PWR_OK hold-up time | 16mS | |
| T6: PWR_OK inactive to DC loss delay | 1mS |
2.5.1 Power Good Signal

3.0 Output Protection
3.1 Total Power Protection (OPP)
Total power 150% max with shut-down and latch off protection.
3.2 Over Voltage Protection (OVP)
| Output Voltage | Max. Act. Voltage | Result |
|---|---|---|
| +3.3V | 4.3V | Shut down & Latch OFF The Group 1 DC Output |
| +5V | 7.0V | |
| +12V | 15.6V | |
| +5VSB | 7.0V | Shut down & Latch OFF |
3.3 Short Circuit Protection (SCP)
The short between any output of group 1 will shut down all group1. The short at group 2 will shut down both group 1 and group 2.
3.4 Over Current Protection (OCP)
Over current protection was designed to limit the current to operate within safe operating conditions. Total current 160% max with shut-down and latch off protection.
3.5 Over Temperature Protection (OTP)
This power supply includes an over-temperature protection sensor, which can trip and shut down the power supply at a preset temperature point. Such an overheated condition is typically the result of cooling fan failure or excessive maximum operation temperature.
3.6 No-Load Situation
No damage or hazardous condition should occur with all the DC output connectors disconnected from the load. The power supply may latch into the shutdown state.
3.7 Reset After Shutdown
Whenever the power supply latches into shutdown state due to a fault condition on its output, the power supply will return to normal operation only after the fault has been removed and the PS_ON# has been pulled low again. If the power supply latches into shutdown state due to a fault condition on 5Vsb, the power supply will return to normal operation only after the fault has been removed and the power switch (power cord) has been cycled off/on (plugged out/in) with a minimum OFF TIME OF 3 SECONDS.
