Teltonika EU/UK/US Single-Port Gigabit Passive PoE Injectors

Introduction

Teltonika PR328EUB, PR328UKB, and PR328USB single-port Gigabit Passive PoE injectors provide both power and network connectivity through a single Ethernet cable. Designed for dependable deployment of compatible network equipment, these injectors offer a practical way to power devices where a nearby DC power outlet is unavailable.

Part Description

These Teltonika passive Power over Ethernet injectors accept a universal 100VAC to 240VAC input and provide a 24VDC PoE output rated for up to 30W. They support Gigabit Ethernet communication at 10/100/1000Mbps, allowing them to power network devices without reducing available Ethernet performance.

The injectors use RJ45 connectors for both network input and PoE-enabled output. Power is delivered using Mode B passive PoE, making the units suitable for equipment specifically designed to accept 24V passive PoE power. The PR328EUB, PR328UKB, and PR328USB variants support different regional AC plug formats for EU, UK, and US installations.

Because these are passive injectors, connected equipment should be verified for compatible voltage, pinout, polarity, and power requirements before installation.

Applications

Potential applications include:

• Powering compatible wireless access points
• Supplying power to cellular routers and gateways
• Connecting outdoor wireless bridge equipment
• Powering IP cameras designed for 24V passive PoE
• Deploying Ethernet-connected IoT gateways
• Installing remote network switches or edge devices
• Providing power for industrial Ethernet communication equipment
• Supporting point-to-point wireless networking links

Industries

These PoE injectors can be used in a range of industries, including:

• Telecommunications
• Industrial automation
• Building automation
• Security and surveillance
• Transportation
• Smart city infrastructure
• Retail and hospitality
• Agriculture and farm monitoring
• Energy and utility monitoring
• Warehousing and logistics

Usage Ideas

1. Remote Wi-Fi Access Point
