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

International Outlet Adapters

Use foreign devices in American outlets and American devices in foreign outlets.

Swap the plug to match the outlet of the region you’re in instead of using separate cords for each country. These adapter cords convert AC voltage to power DC electronics. Designed with switching regulation, they maintain consistent voltage during power fluctuations and don’t get too hot. They meet U.S., Canadian, European, Australian, New Zealand, and Chinese safety standards.

A limited power source (LPS) low-voltage output decreases the risk of electric shock if something fails inside these cords. Class II shock protection means they have two levels of insulation. These cords meet U.S. DOE (Department of Energy) Level VI standards for energy efficiency when they're in-use, as well as when they're plugged in but not in use.

Choose an adapter cord with an output voltage that matches the voltage of your device. The polarity of the adapter cord and your device must also be the same. Look for the polarity illustration on your device or the adapter cord you’re replacing and pick a cord to match.
