Couple these adapters with a cord that matches your outlet and length requirements to run DC-powered electronics. Instead of plugging directly into an outlet, the body of these adapters sits on the floor or other surface, so it remains out of the way and won’t block multiple outlets. These adapters use switching regulation—they produce the stated voltage even when your outlet’s power or the power drawn by your device fluctuates. Most have an LPS low-voltage output, so if something fails inside these adapters, they’ll limit the risk of electrical shocks. They meet U.S., Canadian, and European safety standards. Many also meet U.S. and European standards for energy efficiency.

When choosing an adapter, match the output voltage and polarity of your device. Look for the polarity illustration on your device or the adapter you're replacing. The current you choose should, at a minimum, match your device. You can choose a higher current, but it will not improve performance.

Adapters with an IEC C8 input require power cords with a C7 socket. With Class II shock protection, they have two levels of insulation that prevent electrical shocks.

Adapters with an IEC C14 input require power cords with a C13 socket. They have Class I shock protection and prevent electrical shocks with a combination of insulation and a protective ground.

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. They also have a Means of Protection rating of 2xMOPP, which is the highest level of shock protection available for medical-grade power supplies, so in addition to using them with lab and medical equipment, you can use them with devices that come into contact with patients.

Unlike adapters with bodies that plug directly into an outlet, the body of these adapters rests on a desk or the floor, so it won’t block multiple outlets. Adapters with an IEC C8 input connection require power cords with a C7 socket. Those with an IEC C14 input connection require power cords with a C13 socket.

When selecting an adapter, make sure the DC voltage and amps for the pin output connection can handle the requirements of your device. Choosing a DC voltage and amps that are much higher than you need will not improve performance.

These adapters use switching regulation, which means they produce the stated voltage despite fluctuations in your outlet’s power and the power being drawn by your device. It also means they won’t get too hot.

If you exceed the maximum voltage or load, these adapters shut down to protect both the adapters and the connected equipment.

All of these adapters meet European safety standards. Adapters with Class II shock protection have two levels of insulation to prevent electrical shocks. Those with Class I shock protection prevent electrical shocks with a combination of insulation and a protective ground.

Barrel-Style DC Connectors

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

Housing Connection—Pair connectors that have the same type of housing connection. Push-in connectors are quick to connect and disconnect.

Wire Connection—Choose based on your application. Wire leads come ready to connect and don’t require any preparation. Screw-clamp terminals are easy to use; just insert the wire into the terminal and tighten the screw to clamp it in place.

Receptacles—Mount them in a panel. Receptacles with an off (Normally Open) circuit position turn equipment on when you plug in a device.

Adapters—Convert to the right barrel size for your connection.

Turn-Lock Vehicle DC Connectors

Lock connectors into place for a secure connection in high-vibration environments. The turn-lock design prevents attachment to AC connectors. They power ancillary devices, such as chargers for electronics, from a vehicle. All have corrosion-resistant electrical components.

Plugs have an O-ring that seals out moisture when connected to a socket.

Socket has a watertight cap for protection when not in use.
