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 2 2 an I C management interface. In addition, the I 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.
