The PLATINUM TOOLS TPS200C is a pocket-sized cable tester designed for IT professionals and network technicians working with Power over Ethernet (PoE) installations. This device facilitates the testing of various PoE standards, supporting up to 56 volts and 280 watts of power. The tester operates without internal batteries, drawing power directly from the PoE circuit being tested. It can be deployed in-line with an active PoE device to monitor real-time current flow, or utilized independently in Powered Device (PD) Simulation mode. This simulation capability allows users to determine the maximum power output available from a given PoE power source, aiding in system design and troubleshooting by identifying potential power limitations before device deployment.
