Product Overview - ILX Lightwave LDT-5412B User Manual

Product Overview

The LDT-5412B is a thermoelectric temperature controller capable of stably and accurately
controlling thermoelectric mounts in low power applications. This is achieved by modulating the
current through a thermoelectric load and continuously monitoring the feedback signal
generated from a thermistor temperature sensor. The linear output stage of the LDT-5412B
offers the low current noise necessary to achieve the temperature stability required in most low-
noise and frequency-stabilized laser applications.
Features of the LDT-5412B include:

Long term temperature stability of ±0.01 °C

Linearized thermistor mode allows temperature readout accurate to ±1°C with specific 10 kΩ
thermistors

Bipolar 6 Watt linear output stage

PI control loop with adjustable P gain and fixed I gain

12 Volt bias for operating external fans

Buffered analog measurement output
If cleaning is required, use a clean dry cloth. Do not use solvents.
