PFC-650 Series
Univerter® Power Factor Correction Module
The Univerter PFC -650 Power Factor
Correction modules are AC to DC converters
that operate from wide range AC input voltages
and frequencies with extremely high conversion
ef f iciency and near unit y power f act or ,
producing an output of 375VDC. The PFC-
650U operates from the universal input voltage
range of 90 to 265VAC and input frequencies in
the range of 47 to 440Hz making it ideal for
applications requiring Power Factor Correction
the world over. Model PFC-650W is optimized
for input voltages in the 90 to 180VAC range
and input frequencies in the range of 330 to
880Hz making it an ideal choice for both military
and commercial aircraft applications.
These compact power modules use advanced
electrical design and thermal management
techniques that make them suitable for rugged,
environmentally challenged applications .

Pin Function/Description
AC1, AC2
These are the AC input terminals. The input should
be connected to a suitable input filter in order to for
the PFC module to perform properly and reliably
and to comply with applicable EMI performance
standards.
up capacitor must be located in close proximity to
the PFC output terminals.
LD ENA
This terminal provides logic control to downstream
DC/DC converters. The LD ENA signal will be a
logic low during PFC start up and will switch logic
state (to open collector) upon the PFC output
reaching 340 VDC. If AC input power is lost, the LD
ENA will again go low when the PFC output drops
to 220 VDC. For many RO DC/DC products, it is
not necessary to use the LD ENA terminal. Please
+Out
This is the positive output terminal. It should be
connected to the positive terminal of the hold up
capacitor. The 375 VDC output will appear here
w.r.t the –Out terminal. Hold-up capacitor value
ranges are provided in the specifications. The hold-
