1 +5 V 1.0 A 25 A 30 A 4.90 ~ 5.10 V
2 +12 V 0 A 10 A 12 A 11.28 ~ 12.72 V
3 -12 V 0 A 1 A 2 A -11.40 ~ -12.60V
4 -5 V 0 A 1 A 2 A -4.75 ~ -5.25 V
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.
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
µF capacitor.
