Bel FXP1500-32G Ac-dc power supply Datasheet

The FXP1500-32G is a 1500 watt, power factor
corrected (PFC) front-end, which provides a useradjustable 32 VDC (26-38 VDC range) main output
for test & measurement, RF amplifiers and
transmitters, factory automation, semiconductor
equipment, and other distributed power applications.
The FXP1500-32G provides for true hot-swap with
AC and DC connections at the rear of the model and
can be used for redundant system applications. Its
very small dimensions allow configuration of up to
three units in a 1U rack (up to 4500 W).2 The highlyefficient thermal design with internal fan cooling
permits its use in wide operating voltage and
temperature ranges to provide very high reliability.

The available output power is automatically adjusted depending on the input voltage.
1U standard rack FXR-3-32G for FXP1500-32G is available from Bel Power Solutions.
Automatic derating of main output below 108 VAC to: Io max = 37.5 A (1200 W).
Stress in excess of the absolute maximum ratings may cause performance degradation, adversely affect long-term reliability,
or cause permanent damage to the converter.

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).
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. 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.

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.

overcurrent shutdown, this signal goes high.

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).
