About AC to AC Voltage Transformers

For single-phase equipment, use this formula to find power output: VA = Volts × Amps

For three-phase equipment, use this formula to find power output: VA = Volts × Amps × 1.73

Improve the efficiency of your equipment—wire these transformers to step your input voltage up or down by as much as 20%. Choose an input/output voltage combination that comes closest to matching your application, then choose the power output (in VA) of the equipment you want to operate. You probably won’t find the exact value you need; choose the next highest rating.

Note: Transfomers are labeled with a prewired power output and pre-wired primary and secondary voltages. Single phase transformers are labeled as 120/240V AC primary voltage and 12/24V AC secondary voltage.Three phase transformers are labeled as 120/240V AC primary voltage and 16/32V AC secondary voltage. All possible input voltage and output voltage wiring combinations are listed.
