The TPS200C is a compact, easy-to-use PoE tester designed to measure DC voltage (3.5–56V) and power (up to 280W), including up to 4-pair PoE (IEEE 802.3bt Type 3). Powered by the PoE circuit itself—no batteries required—it can be used inline with a powered device to monitor current flow or in PD Simulation mode to determine available power before device connection. Ideal for field technicians, the TPS200C features a bright scrolling OLED display, automatic mode/polarity detection, and dual RJ45 ports for live PoE testing without disrupting data. It also includes dual 2.1x5.5mm DC jacks and a patch cable for testing DC power supplies and battery backups.
