Changes from Series I
The Series II versions of the Lx and Ls Series are
backward compatible with the original Lx/Ls Series
models. Series II models are different from the original
Lx/Ls Series in the following areas:
•
Standard USB interface has been added.
•
Optional Ethernet LAN interface has been added.
(Option -LAN).
•
The front panel graphic design has been enhanced for
a more pleasing look.
•
The Output 0 and E terminal block is no longer
installed on the standard Lx and Ls units unless the
auxiliary output option -AX is installed. This makes the
standard output terminal block more easily accessible.
No other functional differences exist between the Series I and Series II AC power sources. The RS232C interface is still
available in addition to the USB interface.
The User Manual for Series I models is CI PIN 7004-960 and is available for download. For Series II models, refer to user
manual CI PIN 7004-980 also available for download.
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.
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 GPIBI 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:
•
