The FNP1500/1800 front-ends are power-factorcorrected (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. 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 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 hot-swappable 1500 or 1800-watt AC-DC frontends. 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 Telecom Datacom Servers Distributed power systems North America +1-866.513.2839 Asia-Pacific +86.755.29885888 Europe, Middle East +353 61 225 977 tech.support@psbel.com (c) 2015 Bel Power Solutions, Inc.

BCD.00247_AB FNP1500/FNP1800 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 > 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. To achieve best cooling results sufficient airflow through the unit must be ensured. Do not block or obstruct the airflow at the rear of the unit by placing large components directly at the output connector. 866.513.2839 tech.support@psbel.com (c) 2015 Bel Power Solutions, Inc.

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. 866.513.2839 tech.support@psbel.com (c) 2015 Bel Power Solutions, Inc. BCD.00247_AB FNP1500/FNP1800 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.

If there is a less ideal connection, it is recommended to use an opto-coupler for each unit (IC1, D3, D2). 866.513.2839 tech.support@psbel.com (c) 2015 Bel Power Solutions, Inc.
