Power Shelf
FNR-3 shelves provide up to 5400 watts in a 19" rack.
(See the Rack section for power shelf details.)
Description
The FNP1500/1800 front-ends are power-factor-corrected (PFC) 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. 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 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 FNP1500/1800's
meet international safety standards and display the CE-Mark for the European Low Voltage Directive (LVD).
FNR-3-12G and FNR-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.
