- Optional Sensors Upon Request
The TED8020 Module is a plug-in temperature controller for our PRO8 Platform. It provides excellent temperature stabilization, typically ±0.001 °C (AD590 sensor), for optimal laser operation and other applications requiring precise thermal control. Separate adjustment of the P, I and D settings of the temperature control loop enables optimal settling times for different thermal loads. The TED8020 temperature controller is an ideal companion to our LDC8000 Laser Diode Current Controller Modules. When the TED8020 module is used with a laser diode control module in the same PRO8 chassis, the temperature window protection feature switches off the laser diode current if the temperature of the laser exceeds a used-defined temperature window (high and low threshold).
Damage to the TEC cooler is prevented by setting an adjustable TEC current limit. This can either be set via a recessed potentiometer on the module front panel (hardware limit), via the front panel softkeys or by one of the standard interfaces (software limit). The TED8020 module can be operated with thermistors, AD590/AD592 IC sensors and LM335 transducers. When operated with a thermistor the thermistor calibration constant can be set so that all applicable settings and displays can be done directly in °C, rather than Ohms.
