In applications where PoE (short for “Power over Ethernet”) sourcing equipment is not available, the power injector PA 25W POE-DC offers a compact, convenient solution. It provides both power and data over a single Ethernet cable. The PA 25W POE-DC is optimised for use with a series WS 300V station. Thanks to its compact size, it can easily be installed inside the surface mount box WSSH 50V or the flush mount box WSFB 50V.
