Front-End Power Solutions
Features
(1500 or 1800 Watts)
Front-Ends are available using either a front-mounted
AC receptacle (FNP models) or a rear-mounted AC
connector (FXP models).
I2C Management Software: All FNP/FXP front-ends can be
controlled via Power-One's GUI-driven I2C Management
software and an I2C-to-USB interface (P/N HZZ02002G). An
2
I C Programming Manual describes the complete range of
parameters that can be programmed to the FNP and
FXP1500/1800 front-ends. This manual is available by
searching on "FNP1500" at www.power-one.com.

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 I2C management interface. In addition, the I2C 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.

Fulcrum:
The handle has been designed to allow easy plug-in and -out in a rack system. The handle (lever) fits into a counter piece
(fulcrum) which is fixed to the bottom of the rack. During the plug, the fulcrum holds the unit down and guides it towards the
output connector. The Power-One part number of the fulcrum and its associated mounting accessories is: HZZ01223.

Paralleling Front-Ends:
For parallel use in minimal configuration systems, only the inhibit pins must be shorted to logic GND. All other pins can be left
open. The power supplies will share the output current automatically (droop current share).
For parallel applications without I2C bus, but the use of all other features, it is recommended to connect all logic GND’s on a
backplane together, to connect all Vo2 -, all V o2 + and to leave the internal GND’s open.
The sense wires can be left open or connected to a common load point, the synch-start pin can be left open or connected to a
synch-start circuit, the inhibit pins can be connected together or used individually. All I2C signals (T1-T5, S1, and S2) can be left
open.
Use of a small foil capacitor > 3µF directly at the power outputs of each unit is recommended in order to prevent voltage drops at
the hot plug. For additional information on paralleling see the following Rack (Power Shelf) section.

Racks
(FNR-3-12G, FXR-3-12G, FNR-3-48G, and FXR-3-48G Power Shelves)
Each rack (power shelf) is 1U high with backplane and designed for up to three front-end models in parallel or in n+1 operation.
Each power shelf has:
• Massive copper bus bars for low-loss current distribution.
• Output terminals with two M4-screws on each power tab.
• Two fast-on contacts for system earthing.
• Address coding over five pole DIP switch on each unit, 37-pin D-Sub connector with I2C-lines, monitoring signals and
support functions.
• Provides a start-up synchronization circuit and EMV filters.
