They have active current sharing and up to 8 supplies may be operated in parallel. The supplies may be hot plugged, they recover from overtemperature faults, and have logic and PMBus status signals. Their low profile 1U package and >15W/cubic inch power density make them ideal for delivering reliable, efficient power for telecom and other 12V distributed power systems that include servers, workstations and storage systems.
