Learn About Alpha's Services		CONSTANT VOLTAGE CALCULATOR - COPYRIGHT CROWN® Many people don't realize that a transformer labeled for use with a specific voltage will work just as well at other voltages. This calculator provides power delivered from a transformer tap when driven with other than the rated voltage. This tool is useful when designing audio systems with various amplifiers. This Javascript calculator requires Microsoft Internet Explorer v4.0+ or Mozilla Firefox v1+ browser. Voltage Rating of Transformer Tap Rating  volts  watts New Voltage Power from Tap  volts watts   EXAMPLE: You are installing a distributed system with very long lines. To overcome line loss, you select a 140 volt system. Which transformer tap will feed 10 watts to a loudspeaker with a "70V transformer? • 1. Enter values for both "Voltage Rating of Transformer" and "New Voltage" • 2. Either: •• Enter a value for "Tap Rating" to calculate the power output from the tap at the new voltage. •• Enter a value for "Power from Tap" to calculate the correct transformer tap to achieve the desired power at the new voltage. EQUATION USED TO CALCULATE THE DATA: Pactual = (Vnew squared / Vrated squared) * Prated WHERE: Prated = transformer tap value Pactual = new power from tap Vrated = voltage rating of transformer Vnew = new voltage
