Description
Model LDT-5412 offers stable, low-noise bipolar output in a very economical TE temperature controller. The instrument is optimized for the temperature control of laser diodes and IR photodetectors. An intuitive front panel with a highly visible LED display makes operation simple. The instrument controls and displays thermistor sensor resistance while delivering constant current to a thermoelectric module. The unit’s hybrid proportional-integral control loop offers fast settling times with a typical temperature stability of 0.01°C.

There are three display modes for easy operation: (1) Set Resistance, which displays the set-point resistance (temperature) level; (2) Actual Resistance, which displays the actual resistance of the thermistor sensor; and (3) TE Current, which displays the drive current to the TE module.

The unit’s output can be current limited anywhere within its 0–2 A range by using the recessed front panel LIMIT control knob. During operation, the thermoelectric module current is unconditionally limited to the set-limit value, ensuring that the TE module cannot be overdriven.

Two visual fault indicators located on the front panel provide immediate operator information of fault conditions. The OPEN THERM indicator lights whenever the connection to the thermistor sensor is open. When this condition occurs, the unit’s output automatically shuts off. The LIMIT indicator lights whenever the output is actively limited to the user-set, current limit value.

The incorporation of user-selectable thermistor source currents of 10 µA and 100 µA ensures versatility over a wide range of temperatures and applications. This choice of source currents allows the LDT-5412 to operate over a thermistor control range of 10 O to 200 kΩ. For a typical 10 kΩ thermistor, this corresponds to a temperature range of –20°C to 50°C. Other temperature ranges are also possible through a choice of different thermistors.

The LDT-5412 allows the user to bypass the internal set resistance function of the front panel knob and externally connect a resistor of known value. This is convenient if the operator wishes to reproduce the same temperature quickly and accurately.
