DC-DC Front End Power Supply
PRODUCT OVERVIEW
This highly efficient, 2100W, 54V (or 52.5V) output DC-DC converter is designed to deliver reliable bulk
power to 54V distributed power systems, making it ideal for telecom and other high power density
applications. The power supplies are N+1 redundant, hot-swappable, and have internal cooling fans. The
power supply automatically recovers from overcurrent and overtemperature faults, and status information
2
™
is provided through front panel LEDs, logic signals and its PMBus / I C interface.
