TP-POE-24G 24W Gigabit POE Power Inserter - Reliable 24V Power

Our review of the TP-POE-24G finds it to be a practical, no-nonsense solution for powering remote network devices where a local power source is inconvenient. It is aimed at installers and small IT teams who need a dependable inline power injector that handles Gigabit Ethernet and supplies regulated 24VDC over standard CAT5/6 runs up to 100m. The most compelling reason to buy is the combination of autoranging AC input and built-in Ethernet surge protection, which simplifies installations and reduces the need for additional surge hardware.

Key Features

• Gigabit data passthrough: Accepts data-in on a shielded RJ45 jack and provides data-out with power on the shielded RJ45 output for full Gigabit throughput.
• Regulated 24V output: Supplies a stable 24VDC rail to the powered device, suitable for equipment that requires a dedicated 24V POE feed.
• Autoranging input: Works with AC inputs from 90VAC to 264VAC (50/60 Hz), so it adapts to wide voltage conditions without manual switching.
• Built-in surge protection: Integrated Ethernet surge protection reduces the need for a separate surge protector at the network edge.
• Long cable runs: Delivers power over CAT5 cable for distances up to 100m (328 ft), covering typical Ethernet installation lengths.
• Protections: Includes safeguards against surge, short circuit and overload to protect both injector and remote equipment.

Who It's For

The TP-POE-24G is best for network installers, integrators, and small businesses deploying remote cameras, wireless access points, or other 24V devices where running a separate power line is impractical. Its autoranging AC input and built-in surge protection make it a solid choice for installations in mixed-voltage environments or locations with occasional power spikes.

It is less appropriate for environments that require IEEE 802.3af/at standard POE negotiation or higher wattage POE standards, or for projects that demand centralized POE switch management. Buyers needing managed Gigabit POE switching or standardized POE handshaking should look at dedicated POE switches instead.

Pros & Cons

Pros

• Provides reliable 24VDC power while maintaining Gigabit data throughput over a single shielded RJ45.
• Autoranging 90VAC to 264VAC input simplifies deployment across different mains supplies.
• Built-in Ethernet surge protection reduces component count and installation complexity.
• Includes overload, short circuit and surge protections to safeguard connected devices.

Cons

• Does not implement IEEE 802.3af/at POE signaling, so it may not auto-negotiate with some powered devices expecting standardized POE.
• Limited to 24W class output, so higher-power devices will need a different power source.

Frequently Asked Questions

Can this injector power devices at typical Ethernet distances?
Yes, it supplies power over CAT5 cable for distances up to 100m (328 ft) using pins 4,5(V+) and 7,8(V-).

Does it require a separate surge protector?
No, the unit includes built-in Ethernet surge protection which eliminates the need for a standalone Ethernet surge protector in most installations.

Will it negotiate standard POE with devices?
No, it supplies 24V on spare pairs rather than using IEEE 802.3af/at negotiation, so it may not auto-negotiate with devices that require standardized POE signaling.
