Overview

The Series 850 High Power Rack Mounted Thermoelectric Cooler Controller, like its bench-top counterpart the Series 800 Thermoelectric Cooler Controller, represents a significant advance in the state-of-the-art of thermoelectric cooler (TEC) controllers. 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 850 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 850 High Power TEC Controller features a user-friendly front control panel design.  The Series 850 High Power 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 over-shoot and under-shoot. From the users 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. RS-485 serial communications is standard. RS 232C is optional.    The Series 850 can be ordered in a wide range of output configurations up to 1,000 watts.
