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.

Do not Connected to connect the internal grounds in the system with VO1- line before several units. the output filter The FXP1500-32G power supply exhibit an overcurrent hiccup behavior. This means if either of these supplies 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 FXR-3-32G shelf. 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. +1.866.513.2839 [email protected] © 2015 Bel Power Solutions, Inc.
