What is it?

PoE_v3 module is an Ethernet PoE splitter for 10/100/1000Mbps LAN networks which supports such standards as IEEE 802.3bt with PoE high?power PD interface with automatic MPS & auto class recognition and have 2x (double) DC voltage outputs: 12V + 5.1V at the same time. This is convenient solution for any type of PoE powering with a speed up to 1 Gbps and a need of having two output voltages simultaneously. For example, Raspberry Pi 4 or Raspberry Pi 5 will work without any problem having 5.1V @ 3A as a power input, 12V could be used to control motors from that Raspberry PCB. Module supports 9V to 75V PoE wide input voltage range together with power Levels for up Type-3 60W Operation, power modes higher than 25W must be implemented together with appropriate cooling solutions / additional heatsink. The Automatic MPS function of the module enables applications requiring very low power standby modes. The PoE_v3 module automatically generates the necessary pulsed current to maintain the PSE power.

Operational conditions

Operational temperature: -40 … 85 C Storage temperature: -55 to 150 C Input voltages range (J2 connector) : 9V to 75V PoE wide input voltage range ESD rating: Charged device model (CDM), per JEDEC specification JESD22-C101, all V pins: +-250V Max output current supported: 5A@12V + 3A@5.1V for v.3 Mass: 32 grams for v.3 Communication speed (Ethernet): up to 1 Gigabit per second (1 Gbps) 10/100/1000 Mbps supported

What makes it special?

Double DC Voltage output (12V + 5.1V) makes it ideal with any kind of SBC usage by having the low voltage for single-board computer and 12V for motors / lamps / videocameras or other peripherals. No need to use yet another PCB to decrease the voltage to 5V for SBC.
