HOT SWAP PLUG-IN POWER SUPPLIES
I — INTRODUCTION
SCOPE OF MANUAL.
This Quick Start Guide covers
the installation and operation of the Kepco HSF-1UR
Series of Hot Swap Plug-in Power Supplies. Full specifica-
tions are listed in the applicable 50W, 100W or 150W HSF-
1UR Operator Manual that can be downloaded from the
Kepco web site at:
www.kepcopower.com/support/opmanls.htm#hsf1ur
These power supplies are designed to be installed in
Kepco’s RA 19-1U Rack Adapter. The RA 19-1U Operator
Manual can be downloaded from the Kepco web site at:
www.kepcopower.com/support/opmanls.htm#ra19-1u
DESCRIPTION.
The Kepco HSF-1UR Series power sup-
plies come in 50W, 100W and 150W power ratings. Each
group has 3.3V, 5V, 12V, 15V, 24V, 28V and 48V models
(the 28V 50W models are only available on T, X, C and Y
options). Power Factor Correction (PFC) is included in all
models.
Units may be operated with a nominal 120V a-c/240V a-c
(input voltage range 95 to 264 Va-c), 50-60 Hz (input fre-
quency range 47-440Hz (at 440Hz leakage current
exceeds UL/VDE safety spec. limit). They will also operate
on 125V to 370V d-c input. Overvoltage protection is pro-
vided. Current limiting with automatic recovery from short
circuit is featured. The 100W and 150W 3.3V units and all
50W models are convection cooled; all other 100W and
150W units use forced convection, ball-bearing fans, life
expectancy 50,000+ hours.
OPTIONS.
C option (-1URC) models include a current
sensing resistor, allowing current monitoring within ±10%
(contact Kepco if greater accuracy is required). X option
models (-1URX) include the ability to turn the unit on/off
from a remote location. Y Option models (-1URY) include
both the current sensing resistor and remote on/off capabil-
ities. T Option models (-1URT for 50W Series only) weigh
less, and have improved efficiency (input current) specifica-
tions as well as one additional model (28V).
II — INSTALLATION
MOUNTING THE POWER SUPPLY.
Refer to Figure
and insert HSF-1UR power supply in selected slot until
power supply front panel is flush with rack adapter chassis
and secure with two front panel mounting screws.
CAUTION: Do not overtighten these screws: max.
torque is 2 in.-lbs (0.23 N x m).
CONNECTIONS.
All connections are made at the rear
panel of the RA 19-1U Rack Adapter (see RA 19-1U Oper-
ator Manual). Connect the load to the applicable ± DC
OUTPUT terminals. AC input power is applied via two
INPUT POWER terminal blocks: one supplying slots 2 and
4, the other supplying slots 1 and 3. Make sure to connect
the AC input Neutral, Line and Ground wires to the respec-
tive terminals of the terminal blocks.
REMOVAL.
To remove a power supply, first use the
POWER switch to turn off the unit. Then loosen the two
mounting screws and extract the unit from the RA 19-1U
Rack Adapter.
CAUTION: The ON/OFF switch must be
set to OFF before removing the unit from the rack
adapter.
