Peltier controller is also called TEC controller, is an electronic device which is used to regulate the thermal load temperature. The temperature of the thermal load can be increased or decreased by using a TEC depending on the current direction going through the two terminals of the TEC. By controller the direction of the TEC current, peltier controller can regulate the temperature of the thermal load.
Peltier controller is widely using in laser systems for temperature controlling. Peltier controller is often used with TEC modules,thermistors, and thermally conductive epoxy in order to achieve a best controlling effect. Thermal system is based on Peltier cooler, which has many advantages in temperature regulation, high stability, high accuracy, no moving parts, and wide temperature range. Peltier controller becomes more popular because it can easily drive a TEC to stabilize the temperature of thermal load.
How to select a proper peltier controller for your thermal system? First, you need to check your maximum output current and power supply voltage. If the power supply volage is 3.3V or 5V, max. output current is 2.5A, you can choose TECA1-XV-XV-D. If the power supply voltage is 4.75V-6V, max. output current is 4A, TEC5V4A-D would be a best choice. Moreover, a higher output current like 6A with power supply voltage of 4.75V-6V, then peltier controller TEC5V6A-D is recommended.
These peltier controllers come with compact size and RoHS compliant and have a high efficiency of 90%.
