AOI - Model Series 860 -Dual-Channel Rack-Mounted Thermoelectric Cooler Controller

The Series 860 Dual Channel Rack Mounted Thermoelectric Cooler Controller, like its single channel counterpart the Series 850 Rack Mounted Thermoelectric Cooler Controller, represents a significant advance in the state-of-the-art of thermoelectric cooler (TEC) controllers. The Series 860 provides two separate TEC Controllers in one 19" rack.

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 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. RS485 Serial Communications is standard. RS232C is optional. The Series 860 Thermoelectric Cooler Controller has five standard output power ratings for each channel:
