User Manual Lx / Ls Series
9
1. Introduction
This instruction manual contains information on the installation, operation, calibration and
maintenance of the Lx Series and Ls Series AC power sources.
1.1 General Description
The Lx Series of AC Power Source is a family of high efficiency, rack mountable, AC Power
Source/Analyzer combinations that provide a precise output with low distortion and advanced
measurements. Standard output voltage ranges are 150 Vac and 300 Vac RMS. The Lx Series
can operate in either single or three-phase mode.
The Ls Series of AC Power Source is a family of high efficiency, rack mountable, AC Power
Sources that provide a precise output with low distortion. Standard output voltage ranges are
135 Vac and 270 Vac RMS. The Ls Series is available in either single (-1) or three-phase mode
(3). A
–MODE option is available on –3 Ls models.
For power levels above 4500 VA, two or more Lx or Ls series units can be combined using the
system interface in a parallel mode of operation. These multi chassis systems consist of one
master unit with controller and one or two auxiliary units without controllers. Only the master unit
has a front panel keyboard and display.
Read the installation instructions carefully before attempting to install and operate the Lx / Ls
Series power systems.
1.2 Lx Series and Ls Series Differences
The Lx Series and Ls Series of AC power sources are both based on the same AC power source
hardware platform and share many common components. The differences are primarily in
configuration and options. This manual covers both model series. Some menus and screen
shown in this manual may not apply to Ls Series AC sources without the
–ADV option and / or –
MODE option.
1.2.1 Firmware differences
The Lx Series is fully featured and supports all commands listed in the programming manual.
The Ls Series provides most basic functions in its standard configurations. More advanced
features can be added by specifying the
–ADV (advanced) option. If the –ADV option is installed,
all commands listed in this programming manual are supported. If not, commands related to
arbitrary waveforms and harmonic analysis measurements are not supported and will generate a
“-113 Syntax Error” message.
1.2.2 Hardware differences
In addition to the firmware differences described, the following hardware differences exist
between the standard Lx Ac source and the Ls AC source.
Lx has a 150V / 300 V rms output range pair. Optional ranges of 135/270 (-HV option)
and 200/400 (-EHV option) are available at time of order.
Ls has a 135 V / 270 V rms output range pair. Optional ranges of 156/312 (-HV option)
and 200/400 (-EHV option) are available at time of order.
The Lx rear panel connector labeling is compliant with the California Instruments iL
Series which it replaces and the HP/Agilent model 6834B.
