Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular
application.
warning
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below) chassis ground.
warning
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
Ensure that the AC power line ground is connected properly to the Power Rack input connector or
chassis. Similarly, other power ground lines including those to application and maintenance equipment
must be grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any
cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis.
However, depending on the user‟s application configuration, HIGH VOLTAGES HAZARDOUS TO
HUMAN SAFETY may be normally generated on the output terminals. The customer/user must ensure
that the output power lines are labeled properly as to the safety hazards and that any inadvertent
contact with hazardous voltages is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety
glasses during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San Diego, California, USA, nor any of the subsidiary
sales organizations can accept any responsibility for personnel, material or inconsequential injury, loss
or damage that results from improper use of the equipment and accessories.

KDC Series II DC Power Supplies 1
1 Introduction
1.1 General Description
Figure 1-1: KDC Series DC Power Supply
The Argantix KDC Series DC Programmable Power Supplies are designed specifically for
laboratory test and systems applications requiring single output, variable DC voltage and current
with good ripple and regulation characteristics and sophisticated control and measurement
capabilities. The KDC Series comes in a 3U chassis and can operate in constant current or
constant voltage mode with auto crossover feature. Available Power levels are 5kW, 10kW and
15kW.
Simple menu driven front panel controls enable the voltage and current limit to be changed.
Measurements of voltage, current, peak current and power can also be read from the front panel
LED displays.
The front panel contains an output on/off button for controlling the DC supply output and an output
LED indicator that informs the operator of the output status at all time.
The LCD display is used to display the programmed voltage and current as well as all
measurements. More advanced functions can be accessed through nested levels of menus.
A standard RS232C and optional IEEE 488 interface is available for applications that require
remote control and measurements. While operated remotely, the front panel can be locked out
and the remote control status is indicated by a REMOTE LED.
A power on/off switch can be used to turn the DC supply on or off.

User Manual

1.2 KDC Controllers Series I versus Series II
The original controller version used in the KDC Series has been updated and is now referred to as
KDC II or Series II. The difference is in the way parallel operation of two or more units is
accomplished. KDC units with KDC II controllers have a top-level assembly revision of E as
indicated on the model serial tag. Revisions D and older have an original KDC controller.
Series II KDC models use either controller assembly 5005-721-1 or 5005-724-1. The 5005-724-1
replaced the 5005-721-1 controller as of August 2006 product shipments and is back ward
compatible with the 5005-721-1 controller.
Note: It is not possible to parallel a KDC Series I with a KDC Series II. Thus only
KDC units having the same generation controller can used in master /
auxiliary configuration.
This user manual is intended for use with KDC Units having a revision letter of E or higher. If the
unit you are using has a revision letter of D or lower, use user manual P/N 5005-960 instead. Both
user manuals are distributed on the same CD-ROM or are available for download from the
Argantix web site (www.argantix.com).
1.3 Bench Top use
The KDC Series DC Supply may be used as a bench top unit provided adequate provisions are
made to protect the end-user from touching the output terminals on higher voltage models. To this
end, output covers are provided on all KDC units. These covers must be installed during use and
may only be removed when the unit is not in use and disconnected from AC mains.
Adequate air flow must be maintained at all times so care should be taken not to block the top and
side air intakes or the rear air exhaust. Leave at least 4" of clearance at the back of the unit to
allow proper airflow.
1.4 Equipment Rack use
The KDC Series uses a 19" cabinet with rack ears and can be installed in a standard equipment
rack. Due to the weight of the unit however, it must be properly supported by either a shelf or L
brackets on both sides. The rack ears are not designed to support the full weight of the KDC unit
when installed in a cabinet but only to prevent it from sliding out.
Contact AMETEK Programmable Power customer support ([e-mail]) for
information on rack mount kits for specific cabinets depths. See also paragraph 2.11 for available
rack mount brackets.
Proper airflow must be maintained in the instrument cabinet and the rear of the cabinet should not
be closed off by a door but rather a perforated screen allowing adequate airflow. It is also
important to leave enough clearance above each unit as some of the air intake is on the top
cover.
Note: It is recommended to leave a 1.75" (1 U) space above each KDC unit.
A louvered cover plate to allow some air intake from the front of the cabinet may be used to cover
this space. When planning total cabinet space, allow for 4U per DC supply.
If space is at a premium, units may be mounted with no space. Maximum operating temperature
may have to be derated to 35° under these conditions.

2.10 Parallel Operation
Two or more KDC power supplies of the same voltage range may be combined to create a higher
power system. This requires one master unit (default) and one or more auxiliary units (-AUX). If
both units have the same power level (same model numbers), the sharing will be equal between
the chassis and the programmed current limit set on the master will be multiplied. If units are not
of equal power, the user needs to be aware of the ratio between master and auxiliary(s). This can
be confusing and such a setup is generally not recommended.
The maximum number of KDC units that can be paralleled is 5 (1 master + 4 auxiliary units). The
following specifications apply to multi-box KDC configurations:
Parameter
Current Range:
Multiply by number of KDC units.
Current Programming:
Accuracy:
Multiply by number of KDC units. E.g. for a 3 unit AUX AP
system, accuracy = 0.15 % + 0.3 % FS.
Resolution:
Multiply by number of KDC units. Programmable current is set for
master unit only. Total current will be set current times number of
units.
Current Sharing
Within 2 % typical of combined current range. (If adjusted as
master/aux system.)
Current ripple
Multiply by number of KDC units

2.12 -LC Option
The –LC option has been replaced by the –FT option.
2.13 -FT Option
The –FT option provides a high current bleeder and reduces the output capacitance of each DC
power module to support faster down programming times. This results in further improved fall
times compared to a standard KDC unit. The output noise and ripple specification is increased by
a factor of 2 when adding the –FT option.
This option is available only on models with voltage ranges of 30, 40, 60 or 80V. The –FT option
must be ordered at time of initial order. This option cannot be retrofitted.
The performance specification of KDC power supplies with the –FT option is the same as a KDC
power supply except as noted below:
The voltage loop compensation is adjusted to reduce overshoot normally associated with the
reduced output capacitance of the power modules. This results in reduced load regulation
performance. An auto level control (ALC) mode is provided on –FT models to adjust for load
regulation. The ALC mode applies to CV mode of operation only and is automatically disabled
when the DC supply operates in CC or CP modes. The ALC mode can be turned on from the
CONTROL menu.
