It's no secret that in the past, thermoelectric cooler controllers required a significant amount of hands-on operation to provide satisfactory performance, particularly when variations in the load and/or environmental conditions existed. The Series 860 high power TEC Controller utilizes advanced control technology in combination with auto-tuning capabilities to provide unprecedented performance at a very affordable price. Unlike many industrial controllers that have cluttered front panels, the Series 860 TEC Controller features a user-friendly front control panel design. The panel contains four switches per channel that allow full access to the Series 860 TEC Controller settings. In addition, there are two LED digital displays/ channel that simultaneously display both actual temperature and set point temperature.

The Series 860 TEC Controller features full proportional, integral, and derivative (PID) control that provides exceptionally tight control over a wide temperature range, as well as rapid response to changes in operating conditions. The auto-tuning feature helps to ensure maximum performance over a broad spectrum of operating conditions. Auto-tuning sets the critical PID terms to match the conditions of the application and provides fast response while minimizing overshoot and undershoot. From the user's perspective, the need to make frequent manual adjustments has been virtually eliminated. For unique applications, users have the option to manually adjust the instrument's control parameters as desired.
