Appendix B Power Supply Specifications 59
Output power:
Total DC continuous power does not exceed 260 W. Total DC
peak power does not exceed 280 W. When the input voltage is less
than 100 V
AC
, total DC continuous power should not exceed 220 W.
Ripple and noise:
Peak to peak ripple and noise for +12 V is less than 140 mV. Peak
to peak ripple and noise for other outputs is less than 1% of each
output’s respective voltage at the rated load (namely 115/230 V
AC
).
Measurements were performed with a 15 MHz bandwidth limited
oscilloscope, and each output was terminated with a 0.47
µ
F
capacitor.
Line regulation:
The output line regulation for +12 V is less than ±2%. The output
line regulation for other outputs is less than ±1%, when measured
at each output’s respective rated load and under ±10% changing
input voltage conditions.
Load regulation:
The values for each of the following output numbers were obtained
by changing each output load ±40% from the 60% rated load,
whilst simultaneously keeping all other outputs at 60% of their
respective rated loads.
