SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation, operation and service of the KLP series of
1200W output power, stabilized voltage or current, d-c power supplies manufactured by
KEPCO, Inc., Flushing, New York, U.S.A.
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 KLP Power Supply Series (Figure 1-1) are universal input, automatic crossover, 1200-watt
constant power, voltage/current stabilizers with a full rectangular output characteristic within the
voltage and current ranges listed in Table 1-1.
Six KLP -1200 Models and six KLP -1.2K Models are available, as listed in Table 1-1. The -1200
Models are GPIB and RS 232 compatible; the KLP -1.2K Models are GPIB and LAN compatible.
All models allow remote analog programming.
For each model a multitude of virtual models can be configured. The “rated voltage, maximum
current at rated voltage” and “rated current and maximum voltage at rated current” parameters
define the virtual models available within the limit of 1200 Watts of output power (see Figure 1-
2).
KLP power supplies operate from wide range 100-255V a-c, 45-66 Hz or 125-420V d-c input
source power. Since there are no internal adjustments, KLP Power Supplies offer excellent out-
put voltage/current stability and easy calibration.
Output voltage and current are displayed on independent LED displays. Control of the KLP 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 via either a) IEEE 488.2 (GPIB)
bus, b) RS 232 communication bus [-1200 Models only]. The -1.2K Models also offer direct or
web page control 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 1-4. 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 1-3.
1.3 SPECIFICATIONS
Table 1-1 lists the parameters applicable to individual models. Table 1-2 lists general specifica-
tions applicable to all models except where otherwise noted.
