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
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.

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
