OVERVIEW: PR-59 Series

Laird’s temperature controllers are specifically designed to control thermoelectric assemblies, (TEAs) in a closed loop system. Feedback from a temperature sensor is used to vary the output of the power supply to control the temperature of an enclosure.

Proportional Controllers use proportional regulation to maintain a constant temperature with no swing in the control temperature. This is accomplished by using a PID algorithm to determine the output value and a Pulse Width Modulation (PWM) output to handle the physical control. Proportional Controllers are often used in heating and cooling systems where the temperature must stay constant (with no change) regardless of the change in ambient temperature. The PR-59 is mountable at system level and comes with software to connect to PC. Settings can be adjusted while running TEA, which is beneficial for product development.

Temperature controllers can accommodate more advanced options. Outputs are available for fan, thermoelectric module, thermistor, tachometer sensor on fan, overheating thermostat switch, alarm and LED. However, interface with Laird is required to customize temperature controller settings to meet your unique application requirements. Consult with a Laird engineer on customized solutions relating to specific design criteria. MOQ applies.
