Bulk power dc/dc supply

Designed to deliver bulk power to 54‑Vdc distributed-power applications, the D1U4CS front-end 2,100-W dc/dc power supply is 93% efficient at half load power. With a floating output, users can wire the power supply in a 54-V configuration for data centers or –54-V configuration for telco central-office environments. A 5-Vdc, 0.75-A standby output is also provided. Capable of operating from –40 to –72 Vdc, the 1U unit has a power density of 24.3 W/cu in. Two internal fans provide forced air cooling.

The D1U4CS is N+1 redundant, hot-swappable, and capable of droop current sharing and has a comprehensive set of power control, logic signaling, and operational status functions. The supply automatically recovers from overcurrent and overtemperature faults.
