With a single cord, send data and electricity to Power over Ethernet (PoE) compatible devices. These injectors are commonly used to run devices such as routers and wireless access points in areas where no power outlet is nearby. To run these injectors, you need a power cord and two Ethernet cords (all sold separately). For injectors with an IEC C6 input connection, choose power cords with an IEC C5 socket. For injectors with an IEC C14 input connection, choose power cords with an IEC C13 socket. Connect one Ethernet cord from your network hub to the input of the injector, and the other Ethernet cord from the injector to your device.

These injectors meet U.S., Canadian, and European standards for safety. All have a limited power source (LPS) rating, meaning they meet international safety standards for low-voltage output. They’re also rated for DOE Level VI Efficiency, signaling they comply with Department of Energy efficiency requirements for power usage. Injectors rated for EU CoC Tier 2 Efficiency meet European standards for efficient power usage.

As these injectors convert AC voltage to DC voltage, some noise from the AC voltage will carry into the output. While this won't affect most applications, this noise can interfere with other signals in extremely sensitive applications. The lower the output noise, the less interference it creates.

When choosing an injector, consider how much power your device requires. Injectors with a 15.4W output power are often used with internet-connected phones and simple surveillance cameras. Injectors with a 30W output power commonly power advanced surveillance systems, wireless access points, and lighting. Injectors with a 60W output power are a common choice for building automation components and video conferencing equipment. Injectors with a 90W output power are often connected to TVs and monitors.

Use passive injectors with passive devices. These injectors send power to connected devices at all times; if they are incompatible, the devices could be damaged.

Active injectors check for compatibility with connected devices before sending power, protecting those devices from possible damage. They’re backwards compatible, so injectors with higher output powers can still be used with lower-power devices that meet a different IEEE standard.

Injectors with shielded connections protect from electromagnetic interference (EMI).
