DefinitionThe ripple voltage of the outputs shall be measured at the pins of the outputconnector when terminated in the load impedance specified in figure 1. Rippleand noise are measured at the connectors with a 0.1uF ceramic capacitor anda 10uF electrolytic capacitor to simulate system loading. Ripple shall be measured under any condition of line voltage, output load, line frequency, operation temperature.
Ripple voltage test circuit
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.
Efficiency
Power supply efficiency typical 85% at 115Vac normal voltage.
Remote ON/OFF control
When the logic level “PS-ON” is low, the DC outputs are to be enabled.When the logic level is high or open collector, the DC outputs are to be disabled.
PROTECTION
Over Current Protection
The power supply shall have current limit to prevent the +3.3V,+5V,and +12Voutputs from exceeding the values shown in the following Table. If the currentlimits are exceeded the power supply shall shutdown and latch off.
750W(ST75F-P)
| Voltage | Over Current Limit (Iout limit) |
| +12V | 66A minimum; 90A maximum |
| +5V | 30A minimum; 50A maximum |
| +3.3V | 30A minimum; 50A maximum |
850W(ST85F-P)
| Voltage | Over Current Limit (Iout limit) |
| +12V | 70A minimum; 100A maximum |
| +5V | 30A minimum; 50A maximum |
| +3.3V | 30A minimum; 50A maximum |
1000W(ST1000-P)
| Voltage | Over Current Limit (Iout limit) |
| +12V | 88A minimum; 130A maximum |
| +5V | 35A minimum; 50A maximum |
| +3.3V | 35A minimum; 50A maximum |
Over Temperature Protection
The power supply will be protected against over temperature conditions causedby loss of fan cooling or excessive ambient temperature. In an OTP condition the PSU will shutdown. When the power supply temperature drops to within specified limits, the power supply shall restore power automatically. The OTP circuit must have built in hysteresis such that the power supply will not oscillate on and off due to temperature recovering condition.
Over-Power Protection
The power supply will be shutdown and latch off when output power within105~150% of rated DC output.Note: Assurance machine can work at low voltage, full load won’t damage machine.
Under Voltage Protection
In an under voltage fault occurs, the supply will latch all DC outputs into a shutdown state when +12V,+5V & +3.3V outputs under 85% of it’s maximum value.
Over voltage protection
The over voltage sense circuitry and reference shall reside in packages that areseparate and distinct from the regulator control circuity and reference. No single point fault shall be able to cause a sustained over voltage condition on any or all outputs. The supply shall provide latch-mode over voltage protection as defined in Table.
| Output | Minimum | Nominal | Maximum | Unit |
| +12VDC | 13.3 | 15.0 | 15.6 | Volts |
| +5VDC | 5.70 | 6.30 | 7.00 | Volts |
| +3.3VDC | 3.90 | 4.20 | 4.50 | Volts |
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.+5VSB must be capable of being shorted indefinitely, but when the short is removed, the power supply shall recover automatically or by cycling PS_ON#. The power supply shall be capable of withstanding a continuous short-circuit to the output without damage or overstress to the unit
No load operation
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.
