Introducing the new generation Accuthermo ATEC302 Smart Temperature Controller, an innovative new thermal control platform for precision temperature applications. After 2 years of development for an advanced lab of a special task, we can now offer this model to the general market. Designed specifically for thermoelectric temperature control, the ATEC302 controller incorporates features like PWM, bi-directional power, 4 temperature-zone auto-tune PID, broad sensor support, and an RS232, RS485 or USB interface for managing the controller using a computer. And for configuration flexibility, the ATEC302 and a matching Accuthermo FTX-series H-bridge amplifier are designed as a component solution; simply add the power supply and sensor to match your application requirements and you’re ready to start working with your thermoelectric modules.

Cost-effective Precision Temperature Control for TE Module Applications

Optimized for controlling thermoelectric modules, the ATEC302 controller incorporates features like Pulse Width Modulation (PWM) for efficient module control without using expensive power supply solutions. With a duty cycle of 0.0 to 100.0%, the FTC100 controller’s PWM function offers 1000 levels of precision voltage control. The controller also supports bi-directional temperature control, enabling it to maintain temperature very precisely by using both voltage directions.

Ideal Lab Testbench Platform

The ATEC302 controller offers an ideal solution for TE-based thermal design and laboratory testbench applications. With its panel control interface, users can monitor thermal system status and make adjustments to the controller without the need for an attached computer. And since the ATEC302 also offers an RS232, RS485 and USB interface and Accuthermo’s easy to use ATEC302 Control Center GUI Software, users have the flexibility to write multi-step controller scripts, set parameters, and plot system performance using an attached computer. The ATEC302 incorporates Set-it-and-Forget-it script support, so once you can load your script and then run it with no computer attached. The RS232, RS485 and USB interface also serves as a platform for users to develop customized temperature control software for their application.
 
Supports a Variety of Temperature Sensors
 
While many temperature controllers limit users to one or two sensor types, the ATEC302 is designed to provide maximum flexibility for a variety of thermal control applications. The ATEC302 controller offers broad support for a wide variety of temperature sensors including thermocouples, RTDs and thermistor inputs.

ATEC302 Control Center Software

One More Reason to Select Accuthermo’s ATEC302 Temperature Controller — Easy-to-Use Software
 

While some temperature control applications may only require very simple control (such as holding the temperature at a target set point), many Accuthermo customers need their thermoelectric modules to perform multiple functions, following scripts, dynamically changing temperature and following a thermal cycling program.

Whether you need an easy-to-operate system, or advanced scripting tools, the ATEC302 Control Center software is an excellent solution for you. For ease of use, the graphic interface makes operating the controller a snap. At the same time, the advanced scripting capabilities make the ATEC302 a strong fit for labs, research facilities and product development environments.
