Integrated System
The Ls Series is an improved version of the classic
California Instruments L Series AC power sources.
The Ls Series provides many basic AC source
capabilities at an economical cost. Additional
capabilities such as arbitrary waveform generation
and harmonic analysis can be added as options.

The Ls Series can be ordered in either single
phase (-1) or three phase (-3) congurations.
Power levels range from 3 kVA to 6 kVA in a
single chassis. Multiple chassis can be combined
for power levels up to 18 kVA.

Easy-To-Use Controls
The Ls Series is completely microprocessor
controlled and can be operated from simple front
panel controls. A pair of analog controls located
next to the backlit alphanumeric LCD display
allows output voltage and frequency to be slewed
up or down dynamically. For more advanced
operations, a series of menus is provided using a
dual line high contrast LCD display. An optional
full keypad is available.

Applications
With precise output regulation and accuracy, high
load drive current, multi or single phase mode
and built-in measurement capabilities, Ls Series
AC sources address many application areas of AC
power testing. Additional features such as DO
160, MIL 704, Boeing, or Airbus test standards
are available options that establishes the Ls
Series as a solid choice for avionics or defense
applications. All Ls Series AC sources are standard
equipped with USB and RS232C remote control
interfaces. GPIB and Ethernet (LAN) interfaces are
optional.

Compatibility
Although the standard command language is
SCPI, the Ls Series also offers functional and
bus compatibility with the CI L Series AC power
sources. Using the APE (Abbreviated Plain English)
command syntax, the Ls Series can be used in
existing test systems without having to modify
program code. The APE language is part of the

-GPIB option which includes a GPIB/ IEEE-488
interface.

Ls Series

Transient Programming

To simulate common line disturbance
occurrences, the Ls Series offers a list of transient
steps. These steps can be programmed from the
front panel or downloaded over the interface
using the Interface Instrument Control Software
(GUI) program supplied. The GUI allows libraries
of commonly used line disturbances to be created
on disk for quick recall. Once downloaded, the
transient program can be executed from the PC
or from the front panel. AC transient generation
allows the effect of rapid changes in voltage,
frequency, phase angle and waveform shape on
the unit under test to be analyzed. The Ls Series
is available in either three or one phase output
congurations and offers standard voltage ranges
of 135 Vrms and 270 Vrms. A wide range of
options can be added to customize the Ls Series
to meet your specic application requirements.

Voltage Range Options
Output voltage range options are available to
provide higher voltage outputs. In addition to
the standard 135/270 V range pair, 156/312
Vrms (-HV option) or 200/400 Vrms (-EHV option)
can be specied at the time of order. All voltage
ranges are Line to Neutral. On three phase Ls
Series models, maximum Line to Line voltages are
467 V (standard), 540 V (-HV option) and 692 V
(-EHV option).

Phase Mode
The -MODE option provides automatic switching
between three phase and single phase output
modes. In single phase mode, all output current
is routed to the Phase A output terminal.
The -MODE option is available for 3 phase Ls
congurations.

Waveform Generation
The standard Ls Series provides sine wave output
capability. For more demanding test applications,
the advanced option package (-ADV) adds the
following waveform capabilities:

• Squarewave.

• Clipped Sinewave - Simulates THD levels to test

for harmonic distortion susceptibility.

• Harmonic and Arbitrary (User dened)
waveforms.

Using the provided Windows GUI, dening
harmonic waveforms is as easy as specifying the
relative amplitude and phase angle for each of up
to the 50th harmonic. The waveform data points
are generated and downloaded by the ICS to the
AC source through the standard RS232C, USB
or optional LAN or GPIB bus and are retained in
non-volatile memory. Up to 50 waveforms can be
stored and named for easy recall.

Ls Series - Measurement and Analysis
The Ls Series measurement system is based
on real-time digitization of the voltage and
current waveforms using a 4K sample buffer.
The digitized waveform data is processed by a
Digital Signal Processor to extract conventional
load values such as rms voltage, rms current,
real and apparent power. With the addition of
the advanced features option. (-ADV option),
the same data can also be used to perform
Fast Fourrier Transformation (FFT) to extract
the harmonic amplitude and phase angle of
50 harmonics, or display acquired voltage and
current waveforms.

Standard Measurements
The following standard measurements are
available from the front panel or via the bus:

• Frequency and Phase

• Voltage (rms)

• Current(rms) and Peak Current

• Crest Factor

• Real Power and Apparent Power

• Power Factor

Advanced Measurement Functions
(-ADV option)

Power analysis of EUT load characteristics is
available by adding the -ADV option. Harmonics
up to the 50th harmonic (for fundamental
frequencies up to 250 Hz) and total harmonic
distortion of both voltage and current is provided
as well.

Harmonic analysis data can be displayed on the
front panel display or on the PC using the GUI
program. The GUI can also be used to save and
print harmonics data in tabular, bar graph or time
domain formats.

The acquired voltage and current time-domain
waveforms for each output phase can be
displayed using the GUI program. Waveform
displays on the PC. Available display modes
include voltage and current combined, three
phase voltage, three phase current and true
power. The time-domain data is also available
for transfer to a PC through the bus when using
custom software.

Diagnostics Capability
The AC Source can perform a self test and report
any errors. The self test will run until the rst
error is encountered and terminate. The response
to the self test query command will either be the
rst error encountered or 0 if no error was found.
(Self test passed).

Windows Graphical User Interface
A Windows compatible Instrument Control
Software (GUI) offers a soft front panel interface
for operation from a PC. The following functions
are available through this GUI program:

• Steady state output control (all parameters).

• Create, run, save and print

transient programs.

• Measure and log standard measurements.

With -ADV option:

• Generate and save harmonic waveforms.

• Generate and save arbitrary waveforms.

• Capture and display Voltage and
