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.
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 autoranging, automatic crossover, 1200 watt
voltage/current stabilizers with a full rectangular output characteristic within the voltage and cur-
rent ranges listed in Table 1-1.
Six models are available, as listed in Table 1-1. For each model a multitude of virtual models
can be configured from the front panel. The rated voltage, maximum current at rated voltage,
rated current and maximum voltage at rated current parameters define the virtual models avail-
able within the limit of 1200 Watts of output power (see Figure 1-2).
KLP power supplies operate from wide range 88-255V 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 either analog signals
(applied to the Analog I/O Port), or digital programming via either the IEEE 488.2 (GPIB) or
RS 232 communication bus. Digital control is done with 12 bits of resolution over the entire volt-
age/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.
