1.1 SCOPE OF MANUAL

This manual contains instructions for the installation and operation of the RA 19-7B plug-in rack
adapter (Figure 1-1) used with HSF Series power supplies, manufactured by Kepco, Inc., Flush­ing, New York, U.S.A.

SECTION 1 - INTRODUCTION

1.2 GENERAL DESCRIPTION

FIGURE 1-1.

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 19-7B Model is
designed to accommodate a mix of 50 or 100 Watt (1/8 rack) and 150 Watt (1/6 rack) HSF
power supplies. Some standard configurations are listed below: (see Table 1-2 for filler panels to
cover unused slots):

• Three 1/6 rack modules (slots 5-7) and up to four 1/8 rack modules (slots 1-4) (Figure 1-

2)

• Four 1/6 rack modules (slots 4-7), one or two 1/8 rack modules (slots 1, 2, slot 3 empty),
and filler panel RFP 19-12

• Two 1/6 rack modules (slots 6,7), up to five 1/8 rack modules (slots 1-5), and filler panel
RFP 19-24

• One 1/6 rack module (slot 7), up to six 1/8 rack modules (slots 1-6) and two filler panels
RFP 19-24

NOTE: Contact Kepco Applications Engineering for assistance with non-standard configura-

tions not listed above.

The rack adapter is user-configurable for parallel, series, or independent power supply opera­tion. Forced current sharing and OR’ing diodes for N+1 redundancy are built into the HSF power
supplies. User-configurable keying ensures that only the correct power supply can be installed
in a keyed slot.

1.3 ELECTRICAL

The internal PCB back plate has connectors which interface directly with the power and signal
connectors of HSF Series power supplies, permitting hot swappable insertion and extraction.
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 19-7B Rack
Adapter. Dual input terminal blocks on the back plate assembly (Figure 1-4) distribute input
power to each group of three or four power supplies.

All mechanical specifications are contained in the mechanical outline drawing: Figure 1-5

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.
