California Instruments Ls series ac power sources - available in the UK from TTid (replaces iL Series)
|
|
|

 General Description
The Ls Series is an improved version of the classic California
Instruments L Series AC power sources. It provides many basic AC source
capabilities at an economical cost. Additional capabilities such as
arbitrary waveform generation and harmonic measurements can be added as
options. The Ls Series can be ordered in either single phase (-1) or three
phase (-3) configurations. 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. The Ls Series is completely microprocessor controlled and can be
operated from a simple front panel keypad. 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.
The Lx Series is a similar product with a built-in Power
Analyser and Arbitrary Waveform generator.

L Series
Backward Compatibility
The Ls Series 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 the
need to modify program code. The APE language is part of the -GPIB option,
which also adds the GPIB/ IEEE-488 interface.
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 for AC
power testing. Additional features, like available DO 160 or MIL 704 test
standards, make the Ls Series a good choice for avionics or defense
applications.
All Ls Series AC sources are standard equipped with
RS232C remote control interfaces. An optional GPIB interface is available
as well.
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 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.
Measurements
The following standard measurements are available from
the front panel or via the bus:
- Frequency
- Phase
- Voltage (rms)
- Current(rms)
- Peak Current
- Crest Factor
- Real Power
- Apparent Power
- Power Factor
Configuration Options
The Ls Series is available in either three or one phase output
configurations and offers voltage ranges of 135 Vrms and 270 Vrms. A wide
range of options can be added to customize the Ls Series to meet your
specific application requirements.
Voltage Range Options (-HV
and -EHV)
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) and 200/400 Vrms (-EHV option) can be specified
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 (-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 models (e.g. 4500Ls-3).
Waveform
Generation (-ADV option)
The standard Ls Series provides sine wave
output capability. For more demanding test applications, the advanced
option package adds the following waveform capabilities:
- Squarewave.
- Clipped Sinewave - Simulates THD levels to test for harmonic
distortion susceptibility.
- Harmonic and Arbitrary (User defined) waveforms.
Using the
provided Windows Graphical User Interface (GUI) program, defining harmonic
waveforms is as easy as specifying the relative amplitude and phase angle
for each of up to 50 harmonics. The waveform data points are generated and
downloaded by the GUI to the AC source through the standard RS232C or
optional GPIB bus and are retained in non-volatile memory. Up to 50
waveforms can be stored and given a user defined name for easy recall.
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.
Windows
Graphical User Interface
A Windows compatible Graphical User Interface (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 Current waveforms.
- Measure, display, print and log harmonic voltage and current
measurements.
