CONTROLLEUR DE TEMPERATURE EFFET PELLETIER TE usage, tester ok.

The TC-48-20 is an easy to use yet powerful cool-only or heat-only PWM temperature controller. It is housed in a die-cast aluminum box, incorporates a keypad and display, and is capable of controlling from 0 to 50 volts and up to 20 amps. Two versatile alarm outputs are included, each capable of switching up to 1 amp of current. If a true linear-output control system is desired (for applications extremely sensitive to electrical noise) the TC-48-20 can be used as the control head for high-power, variable-output linear supplies. Most control parameters can be programmed via the built-in keypad, but the controller can also be connected to a computer via an optional RS232 serial cable for more advanced program control as well as data graphing and data logging. The software is shipped as a stand-alone program, but the LabVIEW source code (version 2011 and higher) is also available upon request. A sample read and write command programmed in Python (2.7) is also available for download from the SOFTWARE tab on this web page. Labeled wiring cables are included free of charge when purchasing interconnected standard products on the same order (thermoelectric cooling assembly or module, temperature controller and/or a power supply). The number of cables included (1-3 pairs) will depend on the number of components being interconnected.
