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

Prevent accidental contact with live electrical connections—the screw terminals are covered or recessed. These transformers can handle momentary high-inrush current associated with contactors, solenoids, and relays. Also known as control transformers.

When wired for constant voltage, transformers filter out voltage spikes and electrical noise.
