INTRODUCTION AND SPECIFICATIONS
This manual contains operation and maintenance information for the LDT 5525 Temperature Controller. If you want to get started right away, read Chapter 2, which covers Operation, first.
Product Overview
The LDT-5525 Temperature Controller is a microprocessor-based, precision thermoelectric temperature controller designed for temperature control of laser diodes, detectors and other temperature sensitive devices. The LDT 5525 can be used for laser diode testing, laser diode frequency stabilization, IR detector cooling, and to determine the characteristics of electronic devices. The LDT-5525 combines high analog stability with the versatility of a microprocessor-based instrument. The internal microprocessor controls the operation of the LDT-5525 and performs the non-linear conversion of thermistor resistance to temperature based on two user-defined constants.
You can configure the LDT-5525 to operate with a wide variety of thermistor temperature sensors and TE modules, as well as AD590 series and LM335 series temperature sensors.
Features of the LDT-5525 include:
•Intuitive front panel layout
•Large and easy-to-read green LED display
•Display resolution of 0.1 degree Centigrade
•Output current limit control to safely operate all TE coolers
•Configurable for a variety of thermal sensors
•Output will supply 4 amps, 24 Watts
•Closed-case calibration
