The NI PXIe-1082DC is an 8-slot DC-powered PXI Express chassis engineered for portable and in-vehicle test and measurement systems. It delivers 315 W maximum usable power through a PCI Express backplane, supporting PXI Express, CompactPCI Express, CompactPCI, and standard PXI hybrid modules across dedicated system controller, timing, hybrid peripheral, and PXI Express peripheral slots. Operating from 11 V to 32 VDC input with 65% typical efficiency, the chassis provides stable, low-noise power rails and precision timing synchronization for synchronized multi-module applications.
