INTRODUCTION AND SPECIFICATIONS
This manual contains operation and maintenance information for the LDC-3900
Modular Laser Diode Controller and optional Model 1231 GPIB/IEEE-488.2
Interface. If you want to get started right away, read Chapter 2, which covers
Operation, first.
In the following chapters there are three areas of discussion, one for functions
which are common to both the TEC and the Laser controller, one for the functions
which pertain to the TEC controller only, and one for functions which pertain to the
Laser current source only.
Product Overview
The LDC-3900 Modular Laser Diode Controller may be configured as a
combination current source/temperature controller. It may also be configured with
only current sources or only temperature controllers. The current sources provide
high stability outputs with fully redundant current limit and multiple laser
protection features. The temperature controllers can work with most thermistors
and TE modules to deliver precision laser temperature control over a wide range
of temperatures. The LDC-3900's fast, sophisticated GPIB lets you automate your
experiment.

Specifications
The general specifications for the LDC-3900 are found on page 3. The
specifications for each module are found in the instruction manual for that module.
There are no user serviceable parts in the instrument, including the external fuses in the
AC power entry module. Contact ILX Customer Service (see Comments, Suggestions,
and Problems on page xv for contact information) for information about servicing the
instrument.
Line Voltage Selection
Line voltage selection is made by rotating the line voltage selector insert. The line
voltage selector insert is located inside the power entry module cover. To open
this cover, turn the slot slightly with a screwdriver. The cover will pop out, exposing
the voltage selector insert. Pull out the selector insert, turn it until the desired
voltage selection appears, and re-insert it into the power entry module.
