Power over Ethernet (PoE) Injector No name SPT-1/1P 15.4 W

PoE injector No name SPT-1/1P delivers Power over Ethernet at up to 15.4 W to a single powered device, combining data passthrough and DC power injection over a standard Ethernet cable. It is intended for installations where a PoE-capable switch or midspan is not available, offering a compact solution to power devices such as IP cameras, VoIP phones, and wireless access points that require up to 15.4 W of power. The injector provides one data input port and one combined data-and-power output port, enabling simple integration into existing network cabling without changing switches or routers.

Advantages

The PoE injector supports IEEE 802.3af-class power delivery up to 15.4 W, allowing remote powering of compatible network devices through a single Ethernet cable. Its single-port design reduces installation complexity where only one device requires PoE and avoids the need for separate power adapters at the powered device. The compact form factor makes it suitable for wall- or shelf-mounted deployment and integration into constrained spaces. Using a PoE injector centralizes power sourcing, simplifies maintenance, and preserves network bandwidth by passing data transparently between the input and output ports.

Suitable for

• Powering single IP surveillance cameras that require up to 15.4 W
• Supplying PoE to VoIP desk phones and small office telephony endpoints
• Powering small wireless access points or bridge devices compatible with 15.4 W PoE
• Adding PoE capability to a network segment where the switch lacks PoE

Key specifications

• PoE output power: up to 15.4 W
• Ports: 1 × data input (Ethernet), 1 × data+power output (Ethernet)
• Standards compliance: IEEE 802.3af (PoE)
• Power delivery: DC injection over twisted-pair Ethernet cable
• Typical usage: single powered device (PD) support
• Physical: compact inline injector suitable for desk, shelf, or wall placement

How to use

Connect the network switch or router to the injector's data input port using a standard Ethernet cable. Connect the powered device (for example, an IP camera, VoIP phone, or access point) to the injector's data-and-power output port with another Ethernet cable. Plug the injector into a mains power outlet according to the manufacturer's instructions. The device will receive both data and DC power over the output Ethernet cable; no additional power adapter is required at the powered device. Ensure cabling and connectors are undamaged and that the powered device's power requirements do not exceed 15.4 W.

Usage recommendations

Use Cat5e or higher cabling for reliable power and data transmission and keep cable runs within recommended Ethernet distance limits. Verify device compatibility with 15.4 W PoE (IEEE 802.3af) before connection. If multiple devices require PoE, consider using a multiport PoE switch or multiple injectors to distribute power safely.
