DC Adapters | McMaster-Carr

To run DC-powered lab and medical equipment from your outlet, add a power cord with the plug style and length you need. All of these adapters meet strict IEC standards while some also meet ANSI/AAMI (Association for the Advancement of Medical Instrumentation) standards for use with medical devices.

International AC to DC Adapter Cords

There’s no need for multiple adapter cords or converters, simply swap out the input plugs on these cords to match the outlets of the region you’re in. Use these adapter cords to run DC-powered devices from an outlet in a variety of different countries.

AC to AC Adapter Cords

Power devices that require less than 120 volts AC.

DC to AC Adapter Cords

Plug these cords into a vehicle socket to charge devices that run on AC voltage.

Barrel-Style DC Power Cords

Carry DC power in or out of electronic devices with these cords. All have industry standard barrel-style connections, letting you power electronics from power supplies.

Barrel-Style DC Power Cord Splitters

Send DC power to multiple electronics from one source. With industry standard barrel-style connections, these splitters are compatible with many power supplies and other devices.

Barrel-Style DC Connectors

Made with industry standard barrel-style ends, these connectors carry DC power between electronic devices and power supplies.

Stereo Connectors

These connectors are designed for use in audio equipment.

Panel-Mount Stereo Connectors

Connect audio equipment. These connectors mount to panels of any thickness, as long as you drill a mounting hole first.

DC to DC Converters

DIN-Rail DC to DC Converters

Mount these DC converters to DIN rails on fixtures such as industrial cabinets and electrical panels. By converting voltages, they let you connect power supplies to equipment that requires a different input voltage.

DC to DC Converters

When your power supply sends out DC power at a higher voltage than you need, change to the proper voltage with these converters.
