I — INTRODUCTION
SCOPE OF MANUAL.
This Quick Start Guide covers
the installation and operation of the Kepco HSF-A 1500W
Series of Hot Swap Plug-in Power Supplies. Full specifica-
tions are listed in the HSF-A 1500W Operator Manual that
can be downloaded from the Kepco web site at:
www.kepcopower.com/support/opmanls.htm#hsf
These power supplies are designed to be installed in
Kepco’s RA 19-4C Rack Adapter. The RA 19-4C Operator
Manual can be downloaded from the Kepco web site at:
www.kepcopower.com/support/opmanls.htm#ra19-4c
FACTORY DEFAULTS.
This guide covers only units as
shipped from the factory with the two internal DIP switches
set to default configuration (see Figure 1). For other config-
urations, refer to applicable Operator Manual.
DESCRIPTION.
The Kepco HSF-A 1500W Series are
hot swappable, RoHS-compliant, high frequency switching,
plug-in power supplies. Models may be selected for outputs
of 24V, 36V, 48V or 60V. They employ power factor correc-
tion and are designed to operate in a fault tolerant power
system with a nominal a-c input of 100V a-c to 240V a-c
(input voltage range 85 to 265 Va-c), 50-60 Hz (input fre-
quency range 47-440Hz). A built-in current balancing circuit
and OR-ing diodes allow configuration for hot-swap and
parallel-redundant N+1 operation. All input/output connec-
tions are through a 24-pin connector that plugs in to the
rack adapter. All external connections are made through
the rack adapter’s I/O connector.
NOTE: Both -A and non-A 1500W models can be mixed in
the RA 19-4C Rack adapter and both support par-
allel operation with current sharing, However paral-
lel operation requiring current balancing (forced
current sharing) must use either all -A or all non-A
models.
OPTIONS.
M models include a digital meter which dis-
plays either voltage or current as determined by a front
panel switch. The front panel V or A indicator lights to show
whether voltage (V) or current (A) is displayed. Metered
and non-metered models are completely interchangeable.
FIGURE 1. DIP SWITCH FACTORY DEFAULTS
C Models include a current sense resistor which allows
external current monitoring within 3% (contact Kepco if
greater accuracy is required).
II — INSTALLATION
PRIOR TO MOUNTING.
An internal DIP switch is pre-
configured for the factory defaults (see Figure 1). To
change the factory defaults, refer to the operator manual
and configure the DIP switches prior to installation.
KEYING.
The units are keyed by voltage at the factory.
Refer to the RA 19-4C Operator Manual to make the rack
adapter slot match the HSF-A unit.
MOUNTING THE POWER SUPPLY.
Release the two
cap head screw retaining latches (see Figure 2) by loosen-
ing the cap-head screw approximately 1/2 turn CCW (use
5/32" hex key) and slide to the open (up) position. Insert the
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
