Synchronized start-up circuit for paralleling operation
The FXP1500-48G and FXP1800-48G power supplies exhibit an overcurrent hiccup behaviour. 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 behaviour.
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-3-48G shelf.
