SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation and operation of the RA 19-4C plug-in rack
adapter (Figure 1-1) used with 300W, 600W, 1200W and 1500W HSF power supplies, manufac-
tured by Kepco, Inc., Flushing, New York, U.S.A.
FIGURE 1-1. 1.2 GENERAL DESCRIPTION
Kepco RA 19-4C rack adapters are specifically designed for the installation of Kepco 300W,
600W, 1200W and 1500W HSF Power Supplies into 19-inch EIA-RS-310D standard equipment
racks. The RA 19-4C Model accommodates up to four 300W, 600W, 1200W or 1500W HSF
power supplies (Figure 1-2).
The rack adapter is user-configurable for parallel, series, or independent power supply opera-
tion. Up to four identical units may connected in parallel. Multiple rack adapters may be paral-
leled for additional current capacity. Forced current sharing and OR’ing diodes for N+1
redundancy are built into the HSF power supplies. Redundant a-c inputs are provided to deliver
independent source power to each power supply in a redundant pair. User-configurable keying
ensures that only the correct power supply can be installed in a keyed slot.

1.3 ELECTRICAL
An internal PCB back plate mounts connectors which interface directly with the power and sig-
nal connectors of 300W, 600W, 1200W and 1500W HSF power supplies, permitting hot swap-
pable 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 shows RA 19-4C Rack
Adapter interconnections as well as details of the connectors and DIP switches located on the
rear panel (see Figure 1-4). Dual input terminal blocks on the rear panel (Figure 1-4) distribute
input power to each of the four power supplies. Figure 1-5 is a schematic diagram of the RA 19-
4C Rack Adapter.
All mechanical specifications are contained in the mechanical outline drawing, Figure 1-6.
