NOTES:
4. AC/DC 1 through (N + 1) are multistage AC/DC converters which include AC/DC rectification stage and a DC/DC Converter with a +48VDC
output (also might include a Power Factor Correction stage).
5. DC/DC Converter 1 through (N + 1) are DC/DC converters to provide additional Intermediate Bus.
6. Load “+12V” and Load “+48V” might include other DC/DC converter stages to provide lower voltages such as ±15V, ±5V, +3.3V, +2.5V,
+1.8V etc.
7. Fuse location might vary depending on power system architecture.
