DC/DC power supply D1U54 series

dual-outputwith overcurrent protectionwith overload protection

The D1U54-D-1200-12-HxxPC series are highly efficient 1200 watt, DC input front end modules with a 12V main output and a choice of 3.3V or 5V (20W) standby rails. The power module is able to current share with up to eight (8) other power modules of the same type operating in parallel or N+1 redundancy. The supplies may be hot plugged, and include integral isolation devices. The power modules are fully protected from overload and overvoltage and are able to auto-recover from overtemperature faults. A Status LED is provided on the front panel and additional control and status reporting is provided by hardware logic signals and via a PMBus™ digital interface. A low profile sub 1U height enclosure provides an excellent power density of >28W/in3 that is ideal for delivering reliable, efficient power to servers; workstations; storage systems and other 12V distributed power systems, including direct operation from intermediate bus converters.
