Sorensen DCS Series
1–3 kW
General Purpose Systems Power Supply
• High power density / low ripple and noise
• High programming resolution with
Ethernet interface
• Constant voltage and current mode
• Remote sensing
• Isolated analog control and monitoring (optional)
DCS Applications
The Sorensen DCS Series (hereafter DCS Series)
is ideally suited for a wide range of applications
requiring DC power in a small form factor.
Applications range from manufacturing test and
burn-in of automotive components, avionics
electronics, telecommunications and consumer
products to beam steering, process control and
laboratory R&D use.
The DCS Series is comprised of 1kW, 1.2kW and
3kW programmable power supplies utilizing
switchmode technology to achieve high power
density in a low prole chassis. The design
platform provides a highly reliable power supply
for years of constant use. The unique design is
available in a variety of maximum voltages from
8V to 600V and maximum currents from 1.7A to
350A with low ripple and noise.
This user-friendly platform can be controlled from
the front panel with 10-turn potentiometers to
adjust voltage, current and OVP settings. LEDs
indicate over temperature, remote programming,
shutdown and overvoltage protection
Remote control options allow full computer
control through IEEE-488 (option M9C), LXI
Standard Compliant* Ethernet LAN (option
M130) or RS-232 (options M9C, M130)
Automotive Component Test
The 16-bit resolution of the Ethernet
programming and hardware triggering allows
for detailed sequencing associated with battery
uctuation simulation. The tight load regulation
capability of the DCS series makes it a superior
source for validation and acceptance testing
and burn-in of automotive components. The
20V models, in particular, provide a full range of
testing to simulate battery conditions. Margin
testing of 12V and 14V nominal components,
such as electronic control units (ECU) and
electromechanical components, is easily achieved.
Rackmount ATE Systems
The high power density of the DCS series makes
it ideal for ATE System integration. The wide
variety of voltage and current combinations in 1U
and 2U heights allows multiple voltage outputs
in a small amount of space. The wide variety of
control methods possible, allows easy integration
into legacy systems as well as high speed systems.
Battery Charging
Battery charging requires high accuracy voltage
and stable current output for fast bulk and
absorption phase charging and high accuracy
and stable voltage for oat charging to avoid
“gassing” the battery. The DCS series provides a
high accuracy voltage output to optimize battery
charging. With the remote interface options, the
charging process can easily be automated for
volume production.)
