Conditions of Conformance
When this product is used in applications governed by the requirements of the EEC, the following restric-
tions and conditions apply:
1. For European applications, requiring compliance to the Low Voltage Directive, 2006/95/EC, this power
supply is considered a component product, designed for “built in“ applications. Because it is incom-
plete in construction, the end product enclosure must provide for compliance to any remaining electri-
cal safety requirements and act as a fire enclosure. (EN 61010-1:2001, Cl. 6, Cl. 7, Cl.8, and Cl. 9)
2. This power supply is designed for stationary installation, with mains power applied via a detachable
power supply cord or via direct wiring to the source power terminal block.
3. This power supply is considered a Class 1 (earthed) product. It is intended for use as part of equip-
ment meant for test, measurement and laboratory use, and is designed to operate from single phase,
three wire power systems. This equipment must be installed within a suitably wired equipment rack,
utilizing a three wire (grounded) mains connection. See wiring section of this manual for complete
electrical wiring instructions. (EN 61010-1:2001, Cl.6.10.1)
4. This power supply has secondary output circuits that are considered hazardous, and which exceed
240 VA at a potential of 2V or more.
5. The output wiring terminals of this power supply has not been evaluated for field wiring and, therefore,
must be properly configured by the end product manufacturer prior to use.
6. This power supply employs a supplementary circuit protector in the form of a circuit breaker mounted
on the front panel. This circuit breaker protects the power supply itself from damage in the event of a
fault condition. For complete circuit protection of the end product, as well as the building wiring, it is
required that a primary circuit protection device be fitted to the branch circuit wiring. (EN 61010-
1:2001, Cl. 9.5)
7. Hazardous voltages are present within this power supply during normal operation. All operator adjust-
ments to the product are made via externally accessible switches, controls and signal lines as speci-
fied within the product operating instructions. There are no user or operator serviceable parts within
the product enclosure. Refer all servicing to qualified and trained Kepco service technicians.

SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for installation and operation of the KLP series of 1200W out-
put power, stabilized voltage or current, d-c power supplies manufactured by KEPCO, Inc.,
Flushing, New York, U.S.A. Digital remote operation is described in the KLP Developer’s Guide
which can be downloaded from the Kepco website at
www.kepcopower.com/support/opmanls.htm#klp.
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 1-2.
Seven standard (previously referred to as -1200) KLP Models and seven KLP E-Series Models
(previously referred to as -1.2K) are available, as listed in Table 1-2. The standard Models are
GPIB and RS 232 compatible; the KLP E-Series Models (identified by the E suffix) are GPIB
and LAN (ethernet, LXI) 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 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 90-265V a-c, 45-66 Hz input source power. Since
there are no internal adjustments, KLP Power Supplies offer excellent output 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. 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 1-3.

1.3 OPTIONS
Options are identified by a letter suffix. Unless otherwise noted, options apply equally to stan-
dard and E-Series models, and specifications are not affected.
1.3.1 RAPID OUTPUT DISCHARGE CIRCUIT (RODC) OPTION (R SUFFIX)
The Rapid Output Discharge Circuit (RODC) option (suffix R) is available on all KLP models.
This circuit rapidly discharges the output capacitance, thus significantly reducing response time
to reductions in output voltage.
The circuit consists of a voltage detector that compares the programmed and actual values of
output voltage. The discharge circuit is activated only when the actual voltage exceeds the pro-
grammed value.
Without the RODC circuit, discharge of the total output capacitance (internal and external) is
achieved through a combination of the external load resistance and an internal current sink. For
high load resistance or open circuit conditions at the output, response time (fall time) can vary
from milliseconds to seconds depending upon the magnitude of the high-to-low voltage transi-
tion.
With the RODC option, output fall time is reduced to approximately the same value as rise time,
even with external capacitance equal to 50% of the nominal internal output capacitance. Table
1-1 illustrates the typical performance improvement that can be expected with an open circuit
output.
The RODC circuit will support continuous repetitive discharges from rated model voltage to zero
at rate of up to 1 Hz for the 10V, 20V and 36V models, and up to 0.5 Hz for the 75V, 150V, 300V
and 600V models. Smaller discharge steps will be supported at higher continuous rates; con-
tact Kepco Applications Engineering for additional details. The RODC circuit employs protection
against both peak energy and average power overload conditions by disabling only the RODC
function until conditions recover to normal range; unit performance remains otherwise unaf-
fected. Note that RODC Option units support the TRANsient command (see KLP Developer’s
Guide for details).
