Can PoE injectors support devices requiring more than 60W?

Yes, Power over Ethernet (PoE) injectors can support devices requiring more than 60W, but this depends on the type of PoE standard the injector supports. Here’s a breakdown:

1. IEEE 802.3af (PoE) – 15.4W

Power Output: Up to 15.4W per port, suitable for devices like IP phones, cameras, and small access points.

Not sufficient for devices requiring more than 60W.

2. IEEE 802.3at (PoE+) – 25.5W

Power Output: Up to 25.5W per port, designed to power devices with higher power needs, like some access points and more advanced IP cameras.

Still not enough for devices exceeding 60W.

3. IEEE 802.3bt (PoE++ or 4PPoE)

This standard comes in two power classes:

--- Type 3 (60W): Up to 60W per port. This can support devices like certain high-power access points, PTZ cameras, or advanced network devices.

--- Type 4 (100W): Up to 100W per port. This is designed for high-power devices, such as larger PTZ cameras, video conferencing systems, and devices that need more power for operation.

4. PoE Injectors for >60W

Devices above 60W: To support devices that need more than 60W, you need a PoE++ injector that supports Type 4 (100W).

Example devices: High-performance access points, network appliances, and video surveillance systems with higher power requirements.

Considerations: Ensure both the injector and the device are compliant with the 802.3bt Type 4 standard. The cable (Cat 5e or higher) should also support the power delivery.

5. Alternative Power Solutions:

If the injector cannot provide sufficient power or if you're working with a non-PoE device, you may need to use a separate power supply or an active PoE splitter that can provide more power.

Summary:

To support devices requiring more than 60W, you need PoE++ injectors that comply with IEEE 802.3bt Type 4 (100W). It's essential to ensure that both the injector and the powered device support this higher power output for proper functionality.
