PoE Point of Sale (POS) Terminal

Energy efficiency is the key design parameter of all Power over Ethernet (PoE) Powered Devices (PDs), such as the Point of Sale (POS) terminal. AEM manufactures discrete semiconductors that minimize conduction and switching losses, therefore enhancing the overall energy efficiency of PoE systems.
