33 Appendix B

B.3 24 V

power supply

This is a DC to DC switching mode power supply with a 24 V

input.

Input voltage:+19 ~ +32 V

(normal operation)

Input current:16 A max. @ +24 V

input

Inrush current:10 A max. @ +24 V

input

Output load range:

Table B.3: 24V

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 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.
