PoE Security Camera

Since the amount of source current available to drive Powered Devices (PDs) is limited in Power over Ethernet (PoE) systems, the utilization of energy-efficient semiconductors is critical. AEM manufactures discrete semiconductor solutions that minimize total conduction losses, which greatly assists engineers in enhancing overall energy efficiency and meeting the tight power budget of PDs.
