AC to AC Voltage Transformers

Enclosed Isolating AC to AC Transformers

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

Low-Current AC to AC Transformers

Power low-voltage devices such as alarms and sensors.

Bench-Top Variable-Voltage AC to AC Transformers

Mount these portable transformers to any flat surface.

International AC to AC Transformers

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

Desktop Computer Power Supplies

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

Cords

International Outlet Adapters

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

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.

Detachable-Cord AC to DC Adapters

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

AC to DC Adapter Cords

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

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.

EMI-Filtering IEC Connectors

EMI Filtering IEC Connectors with Power Switch

With a built-in switch, these connectors run power to appliances, power supplies, and other electronic devices while also filtering damaging EMI (electromagnetic interference).

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).

Harsh-Environment EMI Filtering IEC Connectors

Power electronics in damp environments while protecting them from electromagnetic interference.

EMI Filtering IEC Connectors

Bring power into electronic devices while protecting them from harmful electromagnetic interference (EMI).

Air Filter Monitors for Supplied-Air Respirators for Plant Air Lines

Air Filter Monitors for Supplied-Air
Respirators for Plant Air Lines

Track the quality of incoming air as it travels from your air line to your respirator. These monitors display air-quality data, including carbon monoxide and water vapor levels, and sound an alarm if the air is unsafe to breathe.

Electrical Testing Power Supplies

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.

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.

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.
