User Manual Lx / Ls Series II
1. Introduction
This instruction manual (P/N 7004-980) contains information on the installation, operation,
calibration and maintenance of the Lx Series II and Ls Series II AC power sources. The Series II
versions of the Lx and Ls Series are backward compatible with the Series I models. The User
Manual for Series I models is CI P/N 7004-960 and is available for download at
www.programmablepower.com.
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 D 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.
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.

User Manual Lx / Ls Series II
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 models for Series II. Some menus and
screen shown in this manual may not apply to Ls Series AC sources without the –ADV option
and / or –MODE option. See section 1 for difference between Series I and Series II models. This
manual is provided for Series II models.
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.
The Ls rear panel connector labeling is compliant with the California Instruments L
Series.
The Lx Series II comes standard with GPIB, USB and RS232C interfaces. An optional
LAN interface (-LAN) is available.
The Ls Series II comes standard with USB and RS232C, An optional GPIB interface (-
GPIB option) and LAN interface (-LAN) is available.
Note: All interfaces use the SCPI command syntax as described in the programming
manual.
The Lx Series provides both three phase and single-phase output modes, which can be
selected from the front panel or over the bus.
The Ls Series provides either three phase (-3 models) or single phase (-1 models).
Three-phase Ls Series sources may optionally be equipped with the –MODE option,
which provides the same phase mode switching as the Lx Series.
The Lx Series ships with a more advanced keyboard (P/N 6005-702-1), which includes a
numeric data entry pad. This same keyboard is available as an option on the Ls Series
(Option –KP). Customers that prefer the simplified keyboard with dual shuttles (P/N
7004-709-1) can order this on the Lx Series as option –RP.

2. Specifications
Specifications shown are valid over an ambient temperature range of 25 5 C and apply after a
30 minute warm-up time. Unless otherwise noted, all specifications are per phase for sine wave
output into a resistive load. For three phase configurations or mode of operation, all
specifications are for Line to Neutral (L-N) and phase angle specifications are valid under
balanced load conditions only.
Specifications for Ls models are identical to those for the Lx except where noted.
2.1 Electrical
2.1.1 Input
1
Note that operation below 208V L-L AC input is available with the following derating considerations:
1) If operating at less than a 5000 VA output power there will be no affect on the output.
2) If operating in 3-phase mode, with a full-scale output voltage and a frequency less than three times the line
frequency, the voltage distortion may exceed specification between 5500 and 6000 VA output.
3) If operating in 1-phase mode above 5000 VA, above 85% of full-scale output voltage and an output frequency
less than three times the line frequency, the voltage distortion may exceed specification and the output may fault
with a crest factor load more than 2.
In most applications, these conditions are not likely to exits. At AC input voltages of 208 V or higher, the 6000Lx/Ls
meets specifications under all conditions.
