The PoE loads required further isolation to reduce system noise, and therefore a “DC-DC” 1:1 transformer was needed. A BCM Bus Converter Module is the ideal component for this require- ment as it provides isolation, very high efficiency and minimum voltage drop over the load current. The Customer's Challenge More and more systems are connected within an Ethernet network. And powering components like wireless access points, VoIP or remote cameras become a challenge. A customer needed a system to oper- ate reliably over a wide temperature range, and also under harsh environmental conditions. High power supply efficiency was required to keep the
