DC Parallel operation for multi-kW arrays This unique, ultra-low-profile module incorporates OV, OC, UV, short circuit and thermal protection DC-DC conversion and integrated filtering in a chassis- or PCB-mount form factor. 3814 package The NBM offers low noise, fast transient response and High MTBF industry-leading efficiency and power density. Thermally enhanced VIA package Leveraging the thermal and density benefits of Vicor VIA packaging technology, the NBM module offers flexible thermal management Typical Applications options with very low top- and bottom-side thermal impedances. When combined with downstream Vicor DC-DC conversion DC Power Distribution components and regulators, the NBM allows the Power Design Information and Communication Engineer to employ a simple, low-profile design, which will Technology (ICT) Equipment differentiate the end system without compromising on cost or performance metrics. High-End Computing Systems The NBM non-isolated topology allows start up and steady-state Automated Test Equipment operation in forward and reverse directions. It provides Industrial Systems bidirectional protections. However if the powertrain is disabled by any protection and V is present, then a voltage equal to V LO LO High-Density minus two diode drops will appear on the high-voltage side.
