APPLICATIONS
The ultra-stable temperature controller/laser driver instruments
are particularly reliable for diverse fields such as medical,
defense, communications and manufacturing. Applications
include particle and droplet measurement, communications,
manufacturing test, and medical systems. Additionally, our
products are designed for use with electro-optical systems,
airborne instrumentation, spectroscopic monitors, and
medical diagnostic equipment.
GENERAL
• Observe all Cautions and Warnings both in the User Guide and
on the instrument.
• This instrument is designed to be safe to at least the following
conditions: indoor use, 6500 ft (2000 m), 80% maximum
relative humidity for temperatures up to 31ºC and decreasing
linearly to 50% relative humidity at 50ºC, transient overvoltages
to Overvoltage Category 2, and environmental conditions to
Pollution Degree 2.
• Use the LDTC LAB instrument as specified in this guide. If not,
the protection provided by this instrument may be impaired and
the warranty will be voided.
• The LDTC LAB instrument is intended to be used to control
thermoelectrics, resistive heaters, laser diodes and other similar
equipment. Please contact Wavelength Electronics for other
possible applications.
• The LDTC LAB instrument must not be operated in explosion
endangered environments.
• The equipment is not protected against liquid spills. Do not
install where chemicals are used or where liquids could be
spilled into the unit.
• The safety of any system that incorporates the use of the LDTC
LAB series instrument is the sole responsibility of the system
assembler. This includes assembly, mounting, location, special
ambient or application conditions, and connections within the
system.
• Operating outside of the conditions specified in the User Guide
are not recommended for safety reasons.
• Proper setup in the end user’s environment includes:
» Adequately sized thermoelectric and heatsink to properly
manage the heat dissipated by the load.
» Securely mounted temperature sensor for accurate
temperature control.
» Correct connection of the thermoelectric and laser.
» Use of the ACTIVE LOCK connection to protect the load.
