The DBQ series provides a fully regulated, digitally controlled DC output in a ¼-brick format. The DBQ series supports advances in power conversion technology including a digital interface supporting the PMBus protocol for communications to power modules. The DBQ series also incorporates a “droop” load sharing option that allows connecting two or more units together in parallel for demanding powerhungry applications or to provide redundancy in high reliability applications. The converter also offers high input to output isolation of 2250 VDC as required for Power over Ethernet (PoE) applications. The DBQ series...
