Cords

AC to DC Adapter Cords

Plug these adapter cords into a standard outlet and they change AC voltage to DC voltage.

Detachable-Cord AC to DC Adapters

Couple these adapters with a cord that matches your outlet and length requirements to run DC-powered electronics.

International AC to DC Adapter Cords

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.

Universal Laptop Chargers

Charge most standard laptops. These chargers come with five interchangeable tips to suit your device.

Medical-Grade AC to DC Adapters

To run DC-powered lab and medical equipment from your outlet, add a power cord with the plug style and length you need. These adapters meet strict IEC, UL, or ANSI/AAMI standards for use with medical devices.

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.

International Outlet Adapters

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

EMI Filtering IEC Connectors with Integrated Power Supply

EMI Filtering IEC Connectors
with Integrated Power Supply

Change AC voltage to DC voltage and bring power to electronic devices while protecting them from harmful electromagnetic interference (EMI).

Electrical Transforming and Conditioning

Low-Current AC to AC Transformers

Power low-voltage devices such as alarms and sensors.

International AC to AC Transformers

These transformers convert voltage to continuously operate at 80% of the rated power output.

Enclosed Isolating AC to AC Transformers

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

Bench-Top Variable-Voltage AC to AC Transformers

Mount these portable transformers to any flat surface.

AC to DC Electromagnet Transformers

Flip the switch to reverse the magnetic current and release your electromagnet's hold.

DC to AC Transformers for
Sensitive Electronic Loads

These transformers produce AC output that most closely resembles clean, stable AC-generated power.

DC to AC Transformers for Motor Loads

Provide AC power to devices that temporarily draw high output, such as motors.

DC to AC Transformers

Use DC voltage to power devices that run on AC voltage. Also known as inverters and converters.

Sealed Power Supplies

Completely sealed and protected from dust and water, these power supplies don't need a separate electrical panel or enclosure. Instead, mount them directly to machine tools, process control equipment, conveyors, and other equipment found in harsh industrial areas.

Electrical Testing Power Supplies

Ultra-Low-Noise Benchtop Power Supplies

Change AC voltage to DC voltage to power extremely sensitive audio, measuring, and testing devices while keeping electronic interference—often called output or ripple noise—from passing on to the device.

Benchtop Power Supplies

Convert AC voltage into the DC voltages needed to test, design, and prototype a wide variety of electrical circuits and equipment.

Fixed-Voltage Benchtop Power Supplies

No need to adjust the voltage on these power supplies—they’re specifically designed to convert 120V AC to 13.8V DC.

Programmable Benchtop Power Supplies

Use your computer to remotely control these power supplies that convert AC voltage to DC voltage for powering electronics from simple prototypes to advanced testing equipment.

Rack-Mount Power Supplies

Mount these power supplies into standard 19”-wide electronics racks, which can hold multiple electronic devices and keep your benchtop clear.

Desktop Computer Power Supplies

Convert AC voltage to DC voltage to power components inside desktop computers.
