Our new power over ethernet tester is a new generation of easy to use PoE detection RJ45 adapter, ideal for network installers, system integrators, company IT staff and home users to quickly identify the existence of PoE on networks. It is designed to detect whether IEEE 802.3af/at/bt and 24V voltage are running on the cable and to identify the type of power supply equipment,


The PoE tester detects 48V output through mode A and mode B and detects 24V out through mode C. Mode A (supplied on pins 4, 5, 7, 8), and Mode B (supplied on pins 1, 2, 3, 6), Mode C 24V (supplied on pins 4,5,7,8).


Dimensions are 71.3 x 22 x 21.2mm
