Adjustment and Derating:
The Vega 650 series is designed to provide a max output power of 650W at nominal output voltages. The following
procedure must be used to ensure the PSU is operated within its ratings:
•
Calculate user power for each module (volts x amps).
•
Add all the individual module powers together. The total power must not exceed the value given.
•
Calculate secondary transformer turns x amps for each module. See the outputs table for transformer
secondary turns.
•
Add all the module turns x amps together and this must not exceed the ampere turns
•
If necessary reduce the loading until the conditions are met, ie. power and ampere-turns maxima.
