Two independent temperature control channels on one board: Full USB and RS485 remote control is available, and some additional digital I/O lines. The included TEC Service Software ensures full dual channel support. The TEC-1161-10A impresses with its compact design. Can also be used as a digitally controlled power supply.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.
