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