Two independent temperature control channels on one board: full USB and RS485 remote control is available, and some additional digital I/O lines. The free of charge TEC Service Software ensures full dual channel support. The TEC-1122 is the base model of the TEC-Family twin channel devices. Can also be used as a digitally controlled power supply.

Detailed Description

The TEC-1122 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-1122'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 security 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)
