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.
