16 Module Slots Power-over-Ethernet Electronic Load Tester


NuPOE-32EL is a test chassis with power load modules that acts as PD (powered device) of PoE (power over Ethernet). It can support up to 16 modules (for power that is less then 20 Watt) per chassis and they are able to be cascaded as a chain with more test modules for more DUT.

For PD device, there are varieties of power consumption requirement. NuPOE-32EL has different modules in one chassis for test from PSE with different power consumption. It support up to 20, 35, 45, 65 Watt for overload tests. Modules with higher Watt specification can do lower Watt test together with lower Watt module.

Xtramus has total solution to test the PoE DUT in both data flow and PoE simultaneously. Each module on NuPOE-32EL has even number of ports, 2 ports for one pair or 4 ports for 2 pairs. When PSE connect to PoE module such as port 1, the data flow bypasses the module to port 2 for the test from other tester such as NuStreams Chassis. Software utility of Xtramus can run both data flow and PoE tests sequentially or simultaneously.
