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.

أسئلة حول هذا المنتج

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.
