Series Headline 54mm 1U Front End AC-DC Power Supply Converter
Series Description The D1U54P-W-650-12-HBxC series are very high efficiency 650 watt power factor corrected front end supplies with a 12V main output and a 12V Standby. An active (analogue) current share characteristic is provided to allow units to operate in parallel. The power supply may be hot plugged; recovers from overtemperature faults, and has status LEDs on the front panel in addition to hardware signal logic and PMBusā„¢ status signals. The low profile 1U package and 21.4W/cubic inch power density make them ideal for delivering reliable, efficient power to networking equipment, workstations, storage systems and other 12V distributed power architectures.
