CHAPTER 1

INTRODUCTION AND SPECIFICATIONS

Product Overview

Product Overview

The LDX-36000 Series High Power Laser Diode Current Sources are capable of
delivering very high currents, up to 125A CW and 220A QCW with a compliance
voltage up to 35 Volts. These current sources are designed for testing and
controlling multiple high power laser diodes with specially designed features such
as high set-point accuracy, low output noise, forward voltage and photodiode
measurement and an adjustable photodiode reverse bias voltage.

These current sources also offer many laser diode protection features which
protect the laser diode during testing from electrical transients and providing
safeguards such as adjustable voltage and current limits. Low current overshoot
in either CW or QCW mode and closed loop power supply control prevent surge
currents in the case of a device failure with multiple diodes connected in series. A
thermistor based temperature monitor provides additional protection through a
programmable temperature limit which can be used to disable the laser output
when a temperature limit is exceeded. Dual independent interlocks are provided
for further laser and operator protection.

Remote instrument operation is possible on all LDX-36000 Series Current
Sources through an IEEE488/GPIB interface. All instrument controls and
functions are programmable for test sequencing, measurements and data
handling in automated test systems. Synchronization with other measurement or
control instruments is possible with an input and output trigger function with
programmable delays. Multiple test configurations can be saved and easily
recalled through Save and Recall functions from the front panel or through the
GPIB interface.

Installation

Initial Inspection

Grounding Requirements

INTRODUCTION AND SPECIFICATIONS

Installation

After receiving the LDX-36000 Series Current Source, verify that the following
items were shipped along with the instrument:

• LDX-36000 Series User’s Guide

• Power Cord Appropriate for the Local Service

• Shipping Kit

The LDX-36000 Current Source comes with a three-conductor AC power cable.
The power cable must be inserted into an approved three-contact ele ctrical outle t
or used with a three-contact to two-contact adapter with the grounding wire
connected to an electrical ground (safety ground). The AC input and supplied
power cable meets IEC safety standards.

AC Power Requirements

The LDX-36000 Series Current Sources may be operated from a single phase
power source delivering nominal line voltages in the range of 100 to 240 VAC
±10% (all values RMS), from 50 to 60 Hz. Please refer to specifications for proper
line voltage for your instrument. The internal power supplies are autoranging so
no reconfiguration is necessary to operate at different input voltages. Maximum
power consumption depends on the model.

Before connecting the LDX-36000 Current Source to a power source, verify that the AC
power source is within the voltage range printed on the instrument's rear panel.

T o avoid electrical shock hazard, connect the instrument to properly earth-grounded
electrical receptacles only . Failure to observe this precaution may result in severe injury
or death.

GPIB Communications

The IEEE-488 GPIB interface connector is located on the rear panel in the upper
left-hand side of the panel as shown in Figure 1.2. Attach a GPIB cable to the 24­pin connector . The connectors are p olarized to ensure proper orien tation. Fing er­tighten the two jack screws on either side of the connector to prevent the cable
from inadvertently becoming disconnected.

4 LDX-36000 Series



INTRODUCTION AND SPECIFICATIONS

Installation

A total of 15 devices may be connected together on the same GPIB interface b us.
The cables have single male/female connectors on each end so that the cables
can be stacked. This allows multiple cables to be att ached to a sing le instrument.
However, the maximum cable length mu st not exceed 20 meters (65 feet) tot al, or
2 meters (6.5 feet) per device.

The talk and listen addresses of the instrument are identical. This GPIB address
is read by pressing the GPIB/LOCAL button with the address shown on the left­hand display. The instrument comes from the factory with the GPIB address set
to 1. This may be changed from the front panel and is described in the section
entitled Changing the GPIB Address in Chapter 4. For additional information,
refer to Chapter 4 - Remote Operation.

CHAPTER 1

Tilt-Foot Adjustment

The LDX-36000 Series Current Sources come standard with folding front legs an d
two rear feet to use as a benchtop instrument. Extending the front feet so the
instrument front panel is tilted up makes it easier to view the displays. To use
them, place the unit on a stable base and rotate the fro nt legs downward until they
lock into position.

Shipping Kit

The LDX-36000 Series Current Sources come with a shipping kit containing
accessories the user will find useful in getting the instrument operational. These
accessories include screws and clip nuts for rack mounting and a DB-9 connector
and hood to mate with the 9-pin measurement connector on the instrument’s rear
panel. Also included are connectors for mating to the high current output
connectors. For current sources of <50 A, a DB-25 pin connector, pins and hood
are included in the shipping kit. For current sources of >50A, high current output
lugs and screws are provided to attach to the output pads on the rear panel. For
QCW operation with the ILX CC-390 output cable, a high current crown connect or
is also included in the high current shipping kit.

External Interlocks

The instrument's rear panel contains two pairs of terminal blocks which are used
for connecting to two independently monitored interlock circuits. The terminals of
each terminal block must be shorted to satisfy each interlock.

As an example of their use, one interlock could be connected to the flowswitch in
a liquid cooling unit while the other could be tied to a door sensor. However, both
are simply labeled as Interlock 1 and Interlock 2 to allow complete flexibility for the
user.

CHAPTER 1

Obtaining Repair Services

INTRODUCTION AND SPECIFICATIONS

Installation

The instrument may at some point need to be returned to the factory for service
whether or not it is under warranty. If the warranty has expired, there will be a
nominal charge for repair and/or calibration. See the section entitled Returning an
Instrument in the Preface for shipping and contact information.

Potentially lethal voltages exist within the LDX-36000 chassis even with the key switch in
the off position. To avoid electric shock, do not perform any maintenance on the
instrument. Qualified service personne l trained in ESD prevention are required. High
voltages are present on and around the printed circuit boards.

T o disconnect the AC mains supply, remove the power cord from the instrument. If the
AC mains outlet is not easily accessible after instrument installation, ensure that an
external disconnect switch is provided to remove AC power to the instrument.

There are no user-serviceable parts inside the instrument, excepting any external fuses
in the AC power entry module. Contact ILX Customer Service for information about
servicing the instrument.
