SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation and operation of the KLR series of 2400W
output power, stabilized voltage or current, d-c power supplies manufactured by KEPCO, Inc.,
Flushing, New York, U.S.A. The KLR Developer’s Guide covers the digital interfaces remote
programming and can be downloaded from www.kepcopower.com/support/opmanls.htm#klr.
WARNING
DANGEROUS AND LETHAL POTENTIALS ARE PRESENT,
BOTH WITHIN THIS POWER SUPPLY, AND AT THE OUTPUT!
Before proceeding to use the power supply, read this manual very care-
fully. Caution must be used when working with, and making connections
to, this power supply. Use only wires with the proper voltage rating for
high voltage connections.
1.2 GENERAL DESCRIPTION
The KLR Power Supply Series (Figure 1-1) are automatic crossover, 2400-watt, voltage/current
stabilizers with a full rectangular output characteristic within the voltage and current ranges
listed in Table 1-2.
Five KLR Models and five KLR E-Series Models are available, as listed in Table 1-2. The stan-
dard Models are GPIB and RS 232 compatible; the KLR E-Series Models (identified by the E
suffix) are GPIB and LAN (ethernet) compatible. The only difference between standard and E-
Series models is that LAN replaces the RS 232 interface on E-Series models. All models allow
remote analog programming as well as local control.
For each model a multitude of limit models can be configured. Limit models allow the unit to be
configured to maximum settings below the rated voltage and/or rated current. When a limit
model is established the unit will not accept programming values above the user-defined limits.
KLR power supplies operate from wide range 180-265V a-c, 45-66 Hz input source power.
Since there are no internal adjustments, KLR Power Supplies offer excellent output voltage/cur-
rent stability and easy calibration.
Output voltage and current are displayed on independent LED displays. Control of the KLR can
be either local, via the front panel controls and displays, or remote, using 1) either analog sig-
nals (applied to the Analog I/O Port), or 2) digital programming. Digital programming of standard
models is via either IEEE 488.2 (GPIB) bus or RS 232 communication bus. The E-Series mod-
els offer digital programming via either IEEE 488.2 (GPIB) bus or using direct or web page con-
trol via the LAN port. Digital control is done with 12 bits of resolution over the entire
voltage/current range.
The full-rack cross section permits mounting in a standard 19-inch wide rack (for optional chas-
sis slides); see Table 1-5. Load connections are made at the rear panel. Sensing, monitor, and
current share terminals are also available at the rear panel. Outline dimensions are provided in
Figure 1-2.
