SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation and operation of the RA 59 plug-in rack
adapter (Figure 1-1) used with HSP Series power supplies, manufactured by Kepco, Inc., Flush-
ing, New York, U.S.A.
FIGURE 1-1.
1.2 GENERAL DESCRIPTION
The Kepco RA 59 rack adapter is specifically designed for the installation of Kepco HSP Series
Power Supplies into 24.inch EIA standard equipment racks. Each rack adapter accommodates
from one to four HSP power supplies. An internal plate assembly mounts connectors which
interface directly with the power and signal connectors of HSP series power supplies, permitting
pluggable insertion and extraction, while a separate external rear panel contains the fixed power
and signal connections. Separate source power, signal, and load terminations are provided for
each of the four power supply mounting positions. Internal power output configurations differ for
the three models as follows:
Output power connections for all four positions may be connected internally via removable
shorting bus bars. These allow the user to customize each position of the rack adapter for
series, parallel, or independent operation. The unit is shipped with all four positions configured
for independent operation (factory default).
External dimensions and all mechanical and electrical specifications are contained in the outline
drawing: Figure 1-2.
Each rack adapter occupies 5.22 inches (132.5 mm) of vertical space and has a maximum
depth protrusion of 20.75 inches as measured from the mounting surface of the “ear” brackets.
The rack adapter is shipped with mounting ears for flush mounting in EIA 24-inch equipment
racks. The rack adapter can be fitted with optional blank tiller panels in both l/4 and l/2 rack
dimensions if the full complement of four power supplies is not utilized.
