Derated Input Power, Line Transformer Voltage Calculator

Enter Normal Transformer Max.Input Power (Watts)

Enter Normal Secondary Output Voltage for Max.Input Power (Volts)

Enter the reduced Amp Output Power You Wish To Use (Watts)

Calculated Output Voltage=

This calculator will calculate the voltage output from a known transformer if less power than is normal is input.

Enter the usual input power for the usual line output voltage

Press the "Calculate" button"

The resultant reduction in output voltage will be calculated.
