FNP1500/1800 Front-Ends & FNR-3 Power Shelves Data Sheet Features            RoHS compliant for all six substances High density front-ends 15.2 to 18.3 W/in3 Wide input voltage range 85 to 264 VAC 12 V standby voltage, 1A per front-end Highly efficient topology reduces operating costs I2C interface status and control I2C voltage and current limit setting Analog output voltage setting Overtemperature, output overvoltage, and output overcurrent protection ORing circuits for true redundant operation: Vo1: ORing FETs; Vo2: ORing Diodes Status LEDs: AC OK, DC OK, and Fan Fail/Overtemperature Fail FNP1500/1800 front-ends have front-mounted AC input receptacles. Applications     Telecommunications Data communications Servers Distributed power FNR-3 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 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 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 hotswappable 1500 or 1800-watt AC-DC front-ends.

All other pins can be left open. The power supplies will share the output current automatically (droop current share). 2 For parallel applications without I C 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 2 synch-start circuit, the inhibit pins can be connected together or used individually. All I C 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 and FNR-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.
