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.

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). 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 > 3F 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.

Synchronized start-up circuit for paralleling operation Because of hiccup overcurrent protection, when a supply reaches an overcurrent limit, the output voltage will immediately turn OFF and after a delay turn ON again. In parallel use, all power supplies have to start synchronized because of the internal hiccup behavior. Otherwise, the supply which has reached overcurrent first will go to hiccup; this will overload the other supplies, which then will also go to hiccup. When the first supply has recovered from hiccup (hiccup dead time), the others remain in hiccup. This will immediately drive the first one into hiccup once again. This means that without a start-up circuit, a system with several power supplies can never recover from an overload condition or start-up into full load. The following additional circuit, required to reach synchronized startup, is already implemented inside the FNR-3-12G and FNR-3-48G shelves.

Synch Start-up Connection Between Shelves The following connection between the shelves is required to achieve a parallel operation. The synch-start circuits inside the shelves inhibit all power supplies until the last one has recovered from its overcurrent condition and then synchronize the restart of the outputs.

Pin on the D-Sub connector on the backplane
The signals of several racks can be connected together in such a way that all supplies will be inhibited until the last supply has recovered from its overcurrent condition.
Referenced to Logic_GND
NOTE: The Sync-Start pins can be wired together only if the power supplies are connected with a minimal voltage drop on power ground as achieved on a backplane with massive copper bus bars. If there is a less ideal connection, it is recommended to use an opto-coupler for each unit (IC1, D3, D2).

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. Individual fulcrum sets can be also ordered: Power-One part no.: HZZ01223. Note: Each HZZ01223 set contain 2 fulcrums, 2 supports, and mounting accessories.
