I — INTRODUCTION
SCOPE OF MANUAL This Quick Start Guide covers
the installation and operation of the Kepco HSP-A Series of
voltage and current stabilized d-c power supplies. Full
specifications are listed in the applicable Operator's Man-
ual that can be downloaded from the Kepco web site at
www.kepcopower.com/support/opmanls.htm/#hsp
HSP-A are intended for installation in the RA 90 Series of
Rack Adapters. Users must refer to the RA90 Series Quick
Start Guide and Operator manual for connection and con-
figuration details. Both can be downloaded from the Kepco
web site at

FACTORY DEFAULTS This guide covers only units as
shipped from the factory with the three DIP switches set to
default configuration (see Figure 1). For other configura-
tions, refer to HSP-A Operator Manual.
DESCRIPTION The HSP-A power supply (Figure 1-1) is
basically a voltage and current stabilized d-c source with a
relatively sharp crossover between voltage and current
mode operation.
HSP-A power supplies are nominally rated at either 1000 or
1500 Watts of output power, and include active power fac-
tor correction (PFC). HSP-A 1000W power supplies are
designed to operate over the universal a-c power mains
voltage range of 90-277V (47-63Hz), with operation from
125-420V d-c also available. HSP-A 1500W products pro-
vide full power over the a-c mains range of range of 180-
277V a-c, and 1000W output power from 90-132V a-c; con-
tact Kepco for information on operation over other source
voltage ranges. Cooling is provided via an internal d-c fan.
HSP-A permits adjustment of both output voltage (V
current limit (I ), either by internal (front panel pot) or
MAX
external (resistance or voltage) methods, selected via DIP
switches accessed through the top of the unit. Protection
against overvoltage, overcurrent and overtemperature fail-
ures is provided.

FIGURE 1. DIP SWITCH FACTORY DEFAULTS
The HSP-A power supply is specifically designed for use
with Kepco RA 90 Series or similar plug-in rack adapters as
a hot replaceable module in a redundant power system.
Bench top operation not supported. Forced current sharing
and built-in output blocking diodes enhance power system
reliability. Mechanical keying eliminates the risk of incorrect
module insertion. Tool-operated latches on the front panel
guard against casual removal of an operating module.
OPTIONS M models include a digital meter which dis-
plays either voltage or current as determined by a front
panel switch. Another switch allows display of either
actual HSP-A Output or the setpoint. MT models include a
separate switch that allows the meter to display internal
unit temperature, plus an analog signal proportional to
internal generator; T models include the analog signal
only (no meter). L models include built-in free-wheeling
(flyback) diodes used to clamp negative voltage spikes
when used with inductive loads. S models include a vari-
able-speed fan whose speed is controlled by internal unit
temperature.
B models are intended for battery charging applications,
and include a Float/Equalize switch to preset two different
voltage values using two separate front panel adjustment
pots.
