Overview — Less Cost, Less Cabling, Less Maintenance
Designed for demanding environments, Brainboxes Industrial PoE Switches remove the need for costly electrical installations by enabling the transmission of electrical power over the same cable that carries data.
Available with Fast and Gigabit Ethernet, plus SFP, and in a range of enclosures to perfectly fit your application, Brainboxes PoE switches are simple to install, fully conform to IEEE 802.3af/at Ethernet standards for reliable performance, and offer the flexibility to deploy powered devices at almost any location.
Functionality and Features
- 4 PoE+ capable ports
- Fully compliant to IEEE 802.3af/at
- PoE Power Budget: 90W @ 70°C between all 4 PoE ports
- Industrial temp range: -40°C to +70°C
- Redundant dual power inputs: +44V to +57V DC
- Compact design — allows power and data to be combined on the same Ethernet cable
- DIN Rail Mountable or Embedded
