Power Shelf
FNR-3 and FXR-3 shelves provide up to 5400 watts in a 19" rack.
(See the Rack section for power shelf details.)
Description
The FNP/FXP-1500/1800 are power-factor-corrected (PFC) front-ends which (depending on model type) provide a 12 VDC or 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 FNP front-ends have a front-mounted AC receptacle and 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 FNP and
FXP-1500/1800's meet international safety standards and display the CE-Mark for the European Low Voltage Directive (LVD).
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.
