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.
+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-
Astrodyne Corp. 1-800-823-8082
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

more information.
RSS
This terminal is internally connected to inrush
control circuitry on model PFC-650U and is N/C on
model PFC-650W. Model PFC-650W has a built in
inrush limiting resistor whereas for model PFC-650U
the resistor must be provided externally. For PFC650U, connect one end of the inrush limiting resistor
to this terminal. The other end of the resistor will be
connected to –Out. The external inrush resistor
must be chosen to handle the inrush energy which
is determined by the input voltage and hold-up
capacitor value selected. The inrush connection
diagram provides some specific recommendations.
Consult the factory for assistance or additional
information on selecting an inrush resistor.
-Out
This is the PFC negative output terminal. It should
be connected to the negative terminal of the hold up
capacitor. For model PFC-650U, connect one end
of the inrush resistor to this terminal.
Application Diagram
The connection diagram below shows proper connections between PFC-650 modules, hold-up capacitor, inrush
limiting resistor (if required) and DC/DC converters.
For PFC-650W, the inrush limiting resistor is built-in and an external resistor is not required. The resistor is
appropriately sized for a maximum input voltage of 180VAC and a maximum external hold-up capacitor value of
220uF.
For PFC-650U, an external inrush limiting resistor must be provided and connected as shown in the connection
diagram for PFC-650U. A resistor with high surge handling capability should be used. The maximum input
voltage, external hold-up capacitor value and temperature must be considered in choosing a resistor. The
maximum RMS input voltage and resistor value will determine the maximum inrush current. A resistor value
between 10 and 20 ohms should be chosen. The surge energy in the resistor is that required to charge the hold-

up capacitor up to the peak of the line. After that, internal circuitry will both bypass the external resistor with
essentially a short circuit and limit additional inrush current.
