Advanced PoE Splitter Features

Converts PoE Power to 12V DC

The PoE splitter receives power and network data through a compatible PoE Ethernet connection.

It separates the incoming connection into:

• RJ45 Ethernet data output
• 12V DC power output

This allows compatible network equipment without built-in PoE support to use an existing PoE-powered cable run.

Maximum 12W Power Output

The supplied technical description specifies a 12V DC output with a maximum power of 12W.

At 12V, this corresponds to a maximum theoretical output current of 1A.

The supplier recommends keeping connected equipment within the 12W output limit.

Before installation, verify that the connected device operates on 12V DC and does not exceed the splitter’s rated output.

IEEE 802.3af PoE Compatibility

The splitter supports the IEEE 802.3af Power over Ethernet standard.

It is intended to receive power from compatible PoE switches, PoE injectors and other supported power-sourcing equipment.

The supplier also describes compatibility with certain non-standard PoE sources, subject to voltage and wiring requirements.

Important: Non-standard or passive PoE compatibility should be verified before use.

10/100Mbps Ethernet Data Transmission

The splitter supports the following Ethernet standards:

• IEEE 802.3
• IEEE 802.3i 10BASE-T
• IEEE 802.3u 100BASE-TX
• IEEE 802.3x Flow Control

It is suitable for compatible Fast Ethernet network applications.

Gigabit Ethernet operation is not specified.

Built-In Electrical Protection

The splitter includes several protection features:

Short-Circuit Protection: Helps protect connected equipment during supported short-circuit conditions.

Overcurrent Disconnection: Automatically disconnects power during certain excessive-current conditions.

Transformer Isolation: Helps reduce interference and provides electrical separation between supported input and output circuits.

Bridge Rectifier Design: Supports compatible PoE polarity configurations.

These features help improve reliability in properly designed network installations.

PoE Status Indicator

The splitter includes a PoE status indicator to assist installers with identifying incoming power conditions and troubleshooting connections.

Compatible with Non-PoE IP Cameras

The splitter is particularly useful for compatible IP security cameras that require separate:

• 12V DC power
• RJ45 Ethernet network connectivity

Instead of running a separate power cable to the camera, the splitter can receive PoE power through the incoming Ethernet cable and provide the required separate connections.

Simplified Network Installation

A PoE splitter can help simplify installations involving non-PoE network devices.

It is useful where PoE infrastructure is available but the connected equipment requires a conventional DC power input.

Installation and Compatibility Information

Before installing this PoE splitter, verify:

• The network switch or injector provides compatible PoE power.
• The connected device requires 12V DC.
• The connected device consumes no more than 12W.
• The DC output connector matches the equipment.
• The DC output polarity is correct.
• The device supports 10/100Mbps Ethernet.

Important Installation Notes:

• This is a PoE splitter, not a PoE extender or PoE switch.
• It converts compatible incoming PoE into separate Ethernet and 12V DC outputs.
• It does not add PoE functionality to the RJ45 data output.
• The supplier’s detailed description specifies a maximum 12W output.
• The advertised 15W/30W title has not been reconciled with the 12W technical specification.
• An outdoor IP protection rating is not provided. Use a suitable weatherproof enclosure where required.
