SINGLE OUTPUT 3U
HOT SWAP PLUG-IN POWER SUPPLIES
I — INTRODUCTION
SCOPE OF MANUAL. This Quick Start Guide covers
the installation and operation of the Kepco 3U HSF-PFC
Series of Hot Swap Plug-in Power Supplies. Full specifications are listed in the applicable 50W, 100W or 150W HSFPFC Operator Manual that can be downloaded from the
Kepco web site at:
www.kepcopower.com/support/opmanls.htm#hsfpfc
These power supplies are designed to be installed in
Kepco’s RA 19-(X)B Rack Adapters: RA 19-6B for up to six
150W units, RA 19-7B for up to three 150W units, and up to
four 50W or 100W units and RA 19-8B for up eight 50W or
100W units. The applicable RA 19-(X)B Operator Manual
can be downloaded from the Kepco web site at:
www.kepcopower.com/support/opmanls.htm#ra19-xb
DESCRIPTION. The Kepco HSF-PFC Series power supplies come in 50W, 100W and 150W power ratings. Each group has 3.3V, 5V, 12V, 15V, 24V and 48V models (the 100W and 150W groups also have 28V models). Power Factor Correction (PFC) is included in all models.

-PFC
Units may be operated with a nominal 120V a-c/240V a-c
(input voltage range 95 to 264 Va-c), 50-60 Hz (input frequency range 47-440Hz (at 440Hz leakage current
exceeds UL/VDE safety spec. limit). They will also operate
on 125V to 370V d-c input. Overvoltage protection is provided. Current limiting with automatic recovery from short
circuit is featured. Units are convection cooled.
OPTIONS. T option models (-PFCT) use a Kepco RTW power supply instead of the RKW power supply for improved efficiency, less weight, and the addition of a 28V, 50W model. Specifications and, in some cases, model numbers differ slightly. C option (-PFCC) models are identical to the T option, and also include a current sensing resistor, allowing current monitoring within ±10% (contact Kepco if greater accuracy is required). X option models (-PFCX) are identical to the T option, and also include the ability to turn the unit on/off from a remote location. Y Option models (-PFCY) are identical to the T option, and also include both the current sensing resistor and remote on/off capabilities.

II — INSTALLATION
MOUNTING THE POWER SUPPLY. Refer to Figure
1 and insert HSF-PFC power supply into selected slot of
RA 19-(X)B Rack adapter until power supply front panel is
flush with rack adapter chassis and secure with front panel
Phillips head mounting screw.
CONNECTIONS. All connections are made at the rear panel of the RA 19-(X)B Rack Adapter (see applicable RA 19-(X)B Operator Manual). Connect the load to the applicable ± DC OUTPUT terminals. AC input power to each slot is

applied via two INPUT POWER terminal blocks as indicated on the rack adapter rear panel. Make sure to connect
the AC input Neutral, Line and Ground wires to the respective terminals of the terminal blocks.
REMOVAL. To remove a power supply, first use the POWER switch to turn off the unit. Then loosen the mounting screw and extract the unit from the RA 19-(X)B Rack Adapter.
III — OPERATION
Turn the unit on using the front panel POWER switch (see
Figure 1). CAUTION: DO NOT repeatedly toggle the
POWER on/off switch as this may cause unit to fault.
FIGURE 1. COMPONENT LOCATIONS
The MASTER ON LED (amber) goes on under any of the
following three conditions:
• Independent operation.
• Operation in a parallel master/slave configuration
to indicate which unit is the master
• Operation in a parallel master/slave configuration
to indicate that a slave unit is no longer within the
proper specifications for paralleled units. Slave 1
should be optimally adjusted to 40mV less than
master, slave 2 adjusted to 40mV less than slave
1, etc. The maximum allowable difference
between paralleled units is 250mv. The minimum
allowable difference between paralleled units is
25mV. If a slave exceeds these limits, the MASTER ON light goes on.
NOTE: MASTER ON LED not used on 3.3V
model: always OFF.
The following features of the HSF-PFC power supplies
are covered in the applicable Operator’s manual referenced on page 1.
When output voltage is available, the green VDC ON LED
is on. While monitoring output voltage at the front panel
test points, the Output Voltage Adjust trimmer allows
adjustment of the output voltage.
Master/slave parallel configurations of one or more HSFPFC power supplies are covered in the applicable RA 19(X)B Rack Adapter manual.
• Parallel Operation
• Forced Current Sharing
• Current Monitoring (Option C and Y only)
• Remote On/Off (option X and Y only)
• Alarms
• Keying of rack adapter slots by voltage
