PSE controllers to meet power requirements for IEEE 802.3af, 802.3at and 802.3bt
Browse by category
Power sourcing equipment (PSE) supplies power to Ethernet cables using safe, efficient and cost-effective solutions. Our PSE controllers meet the power requirements for IEEE 802.3af, 802.3at and 802.3bt standards. Our extensive portfolio of references designs makes PoE design easier. We also offer a configurable system firmware solution (FirmPSE) for Ethernet switch designers. FirmPSE enables the generation of Ethernet switch code for production-level port power management for complex multi-port (24- and 48-channel) designs with our easy-to-use GUI.

Support the current Ethernet- and Internet of Things-driven climate with our PoE power sourcing equipment
By carrying power through Ethernet cables, PoE makes it possible to connect more devices to the Internet of Things. For switch designs, PoE offers benefits such as:
- Multiple levels of protection for overload, short circuit and overtemperature conditions
- System status and fault diagnostics access through a central controller that can access every port
- Flexibility in the number of ports; our devices support as many as eight channels
