At the factory, the +5 V output was set between 5.00 and 5.10 V, while
other outputs were simultaneously set at 60% of their respective rated
loads.

The -5 V and -12 V outputs can be used at their respective rated loads.
The +5 V output should carry a load of at least 4 A.
The +5 V output should carry a load of at least 4 A.
Output power:
Total DC continuous power does not exceed 250 W. Each output should
be able to operate continuously under its maximum load.

Ripple and noise:
Peak to peak ripple and noise for each output is less than 1% of
each output’s respective voltage. Measurements were performed
with a 15 MHz bandwidth limited oscilloscope, and each output
was terminated with a 0.47
