B.3 24 V
DC
Power Supply
This is a DC to DC switching mode power supply with a 24 V
DC
input.
Specifications
Input voltage: +19 ~ +32 V DC (normal operation)
Input current: 16 A max. @ +24 V DC input
Inrush current: 10 A max. @ +24 V DC input
Output load range:
Table B-8: 24Vdc Power Supply Output load range
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 maximumload.
Ripple and noise:
Peak to peak ripple and noise for each output is less than 1% of each
output’s respective voltage. Measurements were per-formed with a 15
MHz bandwidth limited oscilloscope, and each output was terminated
with a 0.47 mF capacitor.
