system integration.

Compact Power

The KDC Series packs up to 15 kW of DC power
into a small rack mount chassis. Despite the high
power density of this design, the KDC Series
provides low noise, stable output.

A full set of measurements is built-in to provide
instant feedback on EUT load characteristics.

The KDC Series offers all the basic DC power
supply capabilities needed for a wide range of
applications and provides cost effective alternative
to larger and more expensive products typically
used for these applications.

Easy To Use Controls

Simple menu driven operation and familiar rotary
controls for setting voltage and current ensures
that the KDC Series Power Supplies are easy to
operate. All front panel controls including the
rotary knobs are digitally encoded for long lasting,
trouble free operation. The voltage and current
control knobs can be used to quickly slew output
parameters.

The intuitive front panel controls allow for easy
operation of the supply by both novice and
experienced users alike.

Applications

With excellent output regulation and accuracy,
the KDC Series DC Power Supplies support a
wide variety of DC power applications. Examples
include communications, semiconductors,
automotive, information technology and
industrial. The standard RS232C serial interface
supports remote control of all power supply
functions and measurements and allows for easy
integration into ATE systems. Use of standard SCPI
command language syntax and instrument drivers
for popular programming environments further
ease system integration. An optional GPIB/analog
interface is available as well.

KDC Series - Controller Capabilities

All KDC Series Power Supplies use an advanced
DSP based controller with a menu driven user
interface. This controller provides capabilities
not typically found in most DC supplies. Output
Sequencing: Time driven output changes can
be programmed, stored and executed under
program control. Events include steps, sweeps,
drops and surges of voltage and/or current. This
allows a variety of power conditions and DC
tests to be set up and executed from the front
panel. Multiple sequences can be stored in non­volatile memory for quick recall. Parallel Mode:
Several KDC units can be combined to provide
high output current capability using a master
/ auxiliary combination. Output Impedance: A
programmable output impedance function allows
simulation of DC source impedance as a function
of load conditions. Remote Control: The included
KDCGUI program provides easy access to these
and other KDC controller capabilies using a
Windows PC with the standard RS232C or the
optional IEEE-488/GPIB interface.
