Deliver DC power over an Ethernet cable with a passive injector built for practical field installations. The TYCON SYSTEMS POE-INJ-S is designed for deployments where equipment expects passive power delivery and the network architecture calls for a direct, uncomplicated injection point rather than a managed PoE switch. That matters in remote sites, camera runs, wireless links, and other infrastructure builds where power and data need to travel together with minimal hardware overhead. A passive injector can reduce the number of components in the path, simplify cabinet layouts, and make it easier to place powered devices where AC access is limited. This model is aimed at teams that already know the power requirements of the endpoint and want a clean, purpose-built way to feed DC onto the line. It is not about adding features for their own sake. It is about delivering the right kind of power in the right place, with the least amount of complexity between the source and the device.
