MCDODO

MCDODO PoE HAT for Raspberry Pi 4 & 3B+ Professional Isolated 3KV

SKU CH-X5EB-Y3ZPT

Adds galvanically isolated Power-over-Ethernet to Raspberry Pi 4 and 3B+ boards using IEEE 802.3 af/at or passive 48 V sources

  • TypeSingle Board Computers
  • Powers Raspberry Pi 4 and 3B+ through Ethernet cable
  • Galvanic isolation up to 3 kV protects against ground loops
  • Compatible with IEEE 802.3 af/at and passive 48 V switches
  • Enables multi-node clusters from a single PoE switch
  • Requires active airflow — use with ventilated case and cooling fan

Professional Isolated 3KV PoE HAT

This HAT adds Power-over-Ethernet to Raspberry Pi 4 Model B and Raspberry Pi 3 Model B+ boards. It accepts power from IEEE 802.3 af, IEEE 802.3 at and Passive DC 48V sources. The professional model provides galvanic isolation up to 3KV for use with non-compliant switches and injectors. It simplifies deployments by removing the need for individual power adapters.

Builders running clusters or remote nodes

Suits anyone powering multiple boards from a single PoE switch to reduce cabling and adapter count. The isolation protects hardware when the PSE side lacks its own isolation. Not for users without a PoE switch or injector, or those needing a standard power supply. Buyers who want a HAT without active cooling requirements should look elsewhere.

Galvanic isolation up to 3KV

This is the specification that determines suitability for industrial or mixed-voltage environments. It ensures the Pi side remains electrically separated from the Ethernet power source. Without this rating, non-compliant PoE equipment can damage the board. Verify your switch or injector matches the supported IEEE 802.3 af, IEEE 802.3 at or Passive DC 48V standards.

商品問答

Do I need a specific switch standard to power the Raspberry Pi 4 with this HAT?

The HAT works with IEEE 802.3 af and IEEE 802.3 at switches as well as passive DC 48 V power sourcing equipment.

Will the galvanic isolation protect my existing non-isolated PoE injector?

Yes, the 3 kV isolation on the HAT side compensates for injectors that lack PSE-side isolation.

How can I verify the board is receiving power correctly after installation?

The Raspberry Pi 4 will boot and operate normally when the HAT is supplied by a compliant PoE switch or injector.
