Vega 750 Handbook
Adjustment and Derating:
The Vega 750 series is designed to provide a max power of 750W 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 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 modules turns x amps together and this must not exceed amperturns
•
If necessary reduce the loading untill the conditions are met, ie. power and ampere - turns maxima
