One of Meerstetter Engineering's high performance TEC driver. Both channels can be operated separately or bundled (master/slave pairing), full 32 amps DC are then available. Cooling over the base plate remains still perfectly possible. Can also be used as a digitally controlled power supply and will be delivered with the free of charge Meerstetter TEC Controller Software.

Detailed Description | TEC-1123 | TEC Controller

The TEC-1123 is a specialized TEC controller / power supply able to precision-drive two independent Peltier elements or resistive heaters. Each channel features a true bipolar current source for cooling / heating, two temperature monitoring inputs (1x high resolution, 1x auxiliary) and intelligent PID control with built-in autotune. The TEC-1123's hard- and firmware offer various communication and safety options.

The TEC controllers are digitally controllable through our free software or API and scripting. There is even a LabVIEW VI software (PDF) available to operate the TEC controller. Several communication and safety features enhance the functional range.

Other TEC controllers use the power input directly to generate a PWM signal for the Peltier element, which produces interferences. We generate direct current (DC) using SMPS instead, for ripple free output current and higher efficiency, what is advised by Peltier element manufacturers. (More info)
