SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation and operation of the RA 19-8B plug-in rack
adapter (Figure 1-1) used with HSF Series power supplies, manufactured by Kepco, Inc., Flush-
ing, New York, U.S.A.
FIGURE 1-1.
1.2 GENERAL DESCRIPTION
Kepco Series RA 19-(X)B rack adapters are specifically designed for the installation of Kepco
HSF Series Power Supplies into 19-inch EIA standard equipment racks. The RA 19-8B Model
accommodates up to eight 50 Watt or 100 Watt (1/8 rack) HSF power supplies (Figure 1-2).
NOTE: It is also possible to use 150 Watt (1/6 rack) modules in 1/8 rack slots; contact Kepco
Applications Engineering for assistance with non-standard configurations.
The rack adapter is user-configurable for parallel, series, or independent power supply opera-
tion. Forced current sharing and OR’ing diodes for N+1 redundancy are built in to the HSF
power supplies. User-configurable keying ensures that only the correct power supply can be
installed in a keyed slot.
FIGURE 1-2. RA 19-8B RACK ADAPTER WITH HSF POWER SUPPLIES INSTALLED
1.3 ELECTRICAL
An internal PCB back plate mounts connectors which interface directly with the power and sig-
nal connectors of HSF Series power supplies, permitting hot swappable insertion and extrac-
tion. The other side of the back plate assembly, available from the rear, contains the fixed power
and signal connections. Figure 1-3 illustrates the interconnections provided by the RA 19-8B
Rack Adapter. Dual input terminal blocks on the back plate assembly (Figure 1-4) distribute
input power to each group of four powers supplies.
All mechanical and electrical specifications are contained in the mechanical outline drawing:

1.4 MECHANICAL
The rack adapter is equipped with mounting ears for mounting in EIA standard 19-inch racks.
For mounting in non-standard racks, consult Kepco Applications Engineering. The rack adapter
is not configured for slides. Optional blank filler panels (see Table 1-2) are available if the full
complement of power supplies is not utilized.
Mechanical dimensions, material, and finish of the RA 19-8B Rack Adapter is provided in Figure
1-5.
1.5 ACCESSORIES
Accessories for RA 19-8B Rack Adapters are listed in Table 1-2.

SECTION 2 - INSTALLATION
2.1 UNPACKING AND INSPECTION
This equipment has been thoroughly inspected and tested prior to packing and is ready for
operation. After careful unpacking, inspect for shipping damage before attempting to operate. If
any indication of damage is found, file an immediate claim with the responsible transport ser-
vice. See Table 2-1 for a list of equipment supplied.
2.2 CONFIGURING THE RACK ADAPTER
Prior to installation the rack adapter must be configured by the user. Configuration consists of
the following:
• For configurations that use multiple output voltages it is possible to key the rack adapter
to accept only a power supply with corresponding keying (see PAR 2.3).
• Configuring slots for independent, parallel, or series operation. This can be done by
means of internal DIP switches, or externally by wiring the associated I/O mating con-
nector and DC OUTPUT terminals (see PAR. 2.4).
2.3 RACK ADAPTER KEYING INSTRUCTIONS
Series RA 19-(X)B rack adapters incorporate a keying mechanism to prevent accidental inser-
tion of the incorrect model HSF power supply into any position. The HSF power supplies are
keyed by voltage at the factory. The keying mechanism will prevent engagement of any of the
HSF power supply's connectors with those on the rack adapter's back plate unless the key and
keyway align. The user can configure each power supply position of the rack adapter for the
desired voltage in the desired position (see Figure 2-1). First gain access to the interior compo-
nents (PAR.2.3.1), then position the key as required (PAR. 2.3.2).
NOTE: After removing the rear panel, the keying pins can be accessed through the front of the
rack adapter, although it is recommended that the back plate be removed to gain easy
access to interior components.
2.3.1 DISASSEMBLY TO GAIN ACCESS TO INTERIOR COMPONENTS
NOTE: All power supplies must be removed prior to disassembly.
1. Remove eight spacers securing the four I/O connectors to the rear panel
