Hot Swap 12Vdc Input ATX Power Supply - 700 Watt

Product Description

Hot Swap, 700 Watt, ATX, dc to dc converter for 12Vdc input applications. This model provides a 100A 12V pass-through output in a 3.5” x 8.0” by 1.35” open, PCB package. Unit features ATX outputs plus 5V standby. This particular design was developed for use in hot plug, blade server application, where a dc bus was utilized to distribute the power to the racks of its’ single board computers. This design includes a RJ-45 RS485 communications port and a pass-through PCI interconnect.
