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

Enclosed Isolating AC to AC Transformers
Single Phase with Plug and Socket
These transformers have isolated primary and secondary coils to protect your sensitive equipment from input voltage spikes.
When wired as constant voltage transformers, they filter out voltage spikes and electrical noise.
