The FXP1500/1800 front-ends are power-factor-corrected (PFC) and
provide a 48 VDC (1500 or 1800 watt) output, and can be used in hot-swap
redundant systems. Their very small dimensions allow configuration of up
to three units in a 1U rack. The FXP front-ends have a rear-mounted AC
connector. The highly efficient thermal design with internal-fan cooling
permits their use over wide temperature ranges and provides very high
reliability.
Status information is provided with front panel LEDs, logic signals, and via
an I
2
C management interface. In addition, the I
2
C bus can enable the power
supply, set high fan speed, adjust the output voltage, and set the output
current limit. The FXP1500/1800's meet international safety standards and
display the CE-Mark for the European Low Voltage FXR-3-48G power-
shelf solutions provide rectification, system management, and power
distribution, while maintaining high reliability and offering flexibility for
future expansion. The power shelves can be configured with up to three
hot-swappable 1500 or 1800-watt AC-DC front-ends.
