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

Touch-Safe High-Inrush Panel-Mount AC to AC Transformers
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.
