PD.PoE_Trio — Triple-Output PoE Splitter Module (12V + 9V + 5V)

The PD.PoE_Trio is a high-power PoE splitter module designed for makers, engineers, and system integrators who need multiple DC rails from a single Ethernet cable — cleanly, reliably, and at Gigabit speed.

It delivers three regulated output voltages simultaneously:

12V @ 3A

9V @ 2A

5V @ 4A

➡️ Custom voltage configurations are possible on request.

🔌 Key Features

Triple DC outputs at the same time: 12V + 9V + 5V

IEEE 802.3bt / at / af compliant (PoE++, PoE+, PoE)

Supports Type 1 / 2 / 3 / 4 PSE with automatic detection

PG output with inrush completion delay

Automatic Maintain Power Signature (MPS)

Auto-adjusting MPS for different PSE classes

Ultra-low power standby support

Autoclass operation supported

Gigabit Ethernet pass-through (10/100/1000 Mbps)

Wide PoE input voltage range: 9V – 75V DC

Terminal screw connectors for all DC outputs

❓ What Is It?

The PD.PoE_Trio is a Gigabit Ethernet PoE splitter that extracts power from a PoE-enabled Ethernet line and converts it into three independent DC rails — 12V, 9V, and 5V — available simultaneously.

This makes it an ideal power solution for systems where multiple voltages are required without stacking extra DC-DC converter boards.

Typical use cases:

Raspberry Pi 4 / Raspberry Pi 5 powered at 5V @ 3A

Motors, relays, or LED lighting powered from 12V

PoE cameras, sensors, or peripherals powered from 9V

Industrial controllers, SBC clusters, robotics, automation, and lab setups

All of this runs over a single Ethernet cable, with full Gigabit data support.

⚡ Power & PoE Capabilities

Supports PoE power levels up to Type-3 / Type-4 (75W)

Designed for high-power PoE++ applications

Power levels above 25W require appropriate cooling or a heatsink

Automatic MPS generation keeps the PSE alive even in ultra-low-power standby modes

🌡️ Operational Conditions

Operating temperature: −40°C to +85°C

Storage temperature: −55°C to +150°C

Input voltage range: 9V – 75V (PoE)

ESD rating: CDM per JEDEC JESD22-C101 (±250V on all V pins)

Mass: ~45 g

📡 Ethernet

10 / 100 / 1000 Mbps supported

Full Gigabit throughput with PoE power extraction

⭐ What Makes It Special?

Most PoE splitters give you one voltage.

PD.PoE_Trio gives you three — at the same time.

That means:

No extra buck converters

No extra PCBs

Cleaner wiring

Smaller system footprint

Higher reliability

Perfect for SBC-based systems where logic, motors, and peripherals all need different voltages.
