AMS Technologies‘ broad portfolio of TEC temperature controllers / drivers is very well suited for drive and control of thermoelectric coolers (TEC) or thermoelectric modules (TEM) based on Peltier technology. Some models can also drive heating elements based on resistive technologies. Analog and digital TEC drivers with proportional as well as PID type of control are available. In combination with thermistor or RTD temperature sensors, these devices are able to control the temperature of laser diodes or power electronics very precisely, some models can even provide temperature regulation down to <0.001°C.
How to Select the Right TEC Temperature Controller
To decide which TEC temperature controller is most appropriate for driving your Peltier module(s), first sort by your maximum TEC current requirement: choose from our range of TEC drivers with TEC currents from below 1 A up to 28 A. Then choose what mount option would fit best – components for PCB mount, modules for chassis or benchtop mount or instruments for benchtop or rack mount – and also if features like low profile, integrated fans or integrated heat sink are desired.
Our product range offers cost effective and reliable temperature control solutions for your projects, capable of being implemented into an array of pre-existing systems and applicable in wide spectrum of industries.
If you can’t find an off-the-shelf TEC temperature controller that meets your needs, contact the AMS Technologies temperature controller experts – together with our suppliers we can create a temperature control solution tailored to your requirements. We guarantee that we can provide a solution to any thermal management issue, no matter how complex.
Proportional TEC Temperature Controllers:
Like very basic “On-Off” models, proportional TEC temperature controllers are energy efficient. However, the proportional controller gives you better performance. This system functions from a band around the set point to avoid constantly cycling on and off. It does this by reducing percentage of power as you get closer to the set point.
Proportional, Integral, Derivative (PID) TEC Temperature Controllers:
The most complex and accurate type of control, PID, is an abbreviation for Proportional, Integral and Derivative. As an enhanced version of the standard proportional control type, PID calculates the system’s hysteresis to manage the temperature and ensure maximum stability. Proportional TEC temperature control can be slow to climb back to the proper set temperature, thus the integral calculation allows the temperature controller to increase the rate of change to bring the system back to the set temperature faster. The derivative function monitors the change over a much longer period of time than the integral, which allows the system to more accurately compensate for rapid changes in temperature.
