I — INTRODUCTION

SCOPE OF MANUAL This Quick Start Guide covers

the installation and operation of the Kepco HSP Series of
voltage and current stabilized d-c power supplies. Full
specifications are listed in the applicable Operator’s Man­ual that can be downloaded from the Kepco web site at
www.kepcopower.com/support/opmanls.htm/#hsp

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 configura­tions, refer to HSP Operator Manual.

DESCRIPTION The HSP 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

1000W/1500W

HSP power supplies are nominally rated at either 1000 or
1500 Watts of output power, and include active power fac­tor correction (PFC). HSP 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 1500W products provide
full power over the a-c mains range of range of 180-277V
a-c, and 1000W output power from 90-132V a-c; contact
Kepco for information on operation over other source volt­age ranges. Cooling is provided via an internal d-c fan.

HSP permits adjustment of both output voltage (V

external (resistance or voltage) methods, selected via DIP
switches accessed through the top of the unit. Protection
against overvoltage, overcurrent and overtemperature fail­ures is provided.

FIGURE 1. DIP SWITCH FACTORY DEFAULTS

The HSP power supply is specifically designed for use with
Kepco RA 60 or similar plug-in rack adapters as a hot
replaceable module in a redundant power system. Bench
top operation is also supported. Forced current sharing and
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 dis­plays either voltage or current as determined by a front panel switch. Another switch allows display of either actual HSP Output or the setpoint. 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.

II — INSTALLATION

KEYING. The units are keyed by voltage at the factory.

Refer to the Operator Manual for details.

MOUNTING THE POWER SUPPLY To insert in a Kepco Rack Adapter, release the two cap head screw retaining latches (see Figure 4) by loosening the cap-head screw approximately 1/2 turn CCW (use 5/32" hex key) and slide to open (up) position. Insert power supply in the slot, then retighten the cap-head screws CW until snug. DO NOT OVERTIGHTEN! To release, follow the same procedure, except lift the latch to the top of the slot. Be sure to move the latch completely up or down to ensure full engagement/disengagement of the latching mecha­nism. When HSP is not installed in rack adapter, secure latch in open (up) position to prevent damage.

To use as a fixed, rack-mounted unit, see Operator man­ual for details and accessories.

For all installations, provide adequate clearance around
air inlet and exhaust locations.

CONNECTIONS: Figure 2 shows proper connection of one or more loads using either remote or local sensing.

If local or remote sensing is not configured, the unit
will not work properly. Observe polarities: negative

sensing wire must be connected to negative load wire,
and positive sensing wire to positive load wire. When used
with plug-in rack adapters, local sense wires must be con­nected from the I/O connector to the ± studs of the rack
adapter.

Load connections to the HSP power supply are via bus
bars protruding from the rear panel (see Figure 2) or via
the rack adapter output studs.

Load cable or bus bar attachment should use either the
clearance hole of the HSP bus bar, using a 5/16" UNC
nut, bolt and lockwasher, or the rack adapter studs using
hardware supplied with the rack adapter. The proper hard­ware is critical to maintaining intimate contact between the
load conductor and output bus bar.

LOCAL ERROR SENSING

FIGURE 2. LOAD CONNECTIONS

PRELIMINARY ELECTRICAL CHECK A simple operational check after unpacking and before equipment installation is advisable to ascertain whether the power supply has suffered damage resulting from shipping.

1. Power supply will not operate unless remote

sense lines are properly connected to output ter­minals! Connect remote sense terminals to output

bus bars using mating I/O Connector (Kepco P/N 142-

0422) or other means as shown in Figure 2.

2. Connect power supply to source power. Connection
can be made using either a North American linecord
set (Kepco P/N 118-0776) or using a custom linecord

terminated at one end with an IEC 320/C19 plug
(Kepco P/N 142-0381).

3. Connect a static load, R, across output terminals.
Load value is determined by HSP nominal output volt­age and must be capable of handling 2% of power
supply output rating (20 watts minimum). R is calcu­lated as approximately equal to output voltage
