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 Step-Up/Step-Down AC to AC Transformers

Improve the efficiency of your equipment—wire these transformers to step your input voltage up or down by as much as 20%.

Enclosed Isolating AC to AC Transformers

These transformers have isolated primary and secondary coils to protect your sensitive equipment from input voltage spikes.

Enclosed Voltage-Stabilizing AC to AC Transformers

Protect equipment from electromagnetic interference and maintain power during three-millisecond power dips.

Enclosed Step-Down AC to AC Transformers

Also known as auto transformers, these decrease incoming voltage to meet the needs of your application.

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.

High-Inrush Panel-Mount AC to AC Transformers

These transformers can handle momentary high-inrush current associated with contactors, solenoids, and relays.

Harsh Environment High-Inrush
Panel-Mount AC to AC Transformers

Sealed coils protect against dust, dirt, oil, and moisture. These transformers can handle momentary high-inrush current associated with contactors, solenoids, and relays.

DIN-Rail/Panel-Mount High-Inrush
AC to AC Transformers

Use with DIN-rail to install wherever you need these transformers or mount them to a panel. They can handle momentary high-inrush current associated with equipment start-up.

Outlet Box/Panel-Mount
High-Inrush AC to AC Transformers

Use the included outlet box cover or mount these transformers to a panel. They can handle momentary high-inrush current associated with equipment start-up.

Low-Current AC to AC Transformers

Power low-voltage devices such as alarms and sensors.

AC to AC Adapter Cords

Power devices that require less than 120 volts AC.
