General Specifications Intel® Server Boards SE7320SP2 and SE7525GP2 8.4.2 Voltage Recovery Timing Specifications The power supply must conform to the following specifications for voltage recovery timing under load changes: Voltage shall remain within +/- 5% of the nominal set voltage on the +5 V, +12 V, 3.3 V, 5 V and -12 V output, during instantaneous changes in load shown in the following table. Voltage regulation limits shall be maintained over the entire AC input range and any steady state temperature and operating conditions specified. Voltages shall be stable as determined by bode plot and transient response. The combined error of peak overshoot, set point, regulation, and undershoot voltage shall be less than or equal to +/-5% of the output voltage setting. The transient response measurements shall be made with a load changing repetition rate of 50 Hz to 5 kHz. The load slew rate shall not be greater than 0.2 A/ s. Table 105.
