Product Overview:

Affordable TEC Controller Board with Digital Interface

This small footprint OEM TEC controller is designed to work with NTC/Thermistor type temperature sensors. The TEC-8A-24V-PID-HC has a small footprint and has holes for mounting to a chassis or a lab table. Its small size and versatility make it widely used in many applications.

The TEC-8A-24V-PID-HC includes a UART digital control port which allows the user to set and monitor the controller parameters. The controller operates in heating- and cooling-mode using Pulse Width Modulation output through an H-bridge architecture. It also has an open collector output which provides an output control signal for other devices. On-Board LED's show heating and cooling status.

120 Watts of TEC Output Power

These TEC controllers with up to 120 Watts of cooling and heating power are specifically designed for laser diodes.

It is designed to work with 12V Peltier modules, but works well with all Peltier modules with supply voltage ratings in the range of 7.5 V to 15 V.

The UART can also be used to read the temperature set-point, actual temperature, and PID parameter values. The adjustable PID parameters allow the controller to be adapted to almost any temperature control system. Depending on the stability of the ambient temperature, this TEC controller is able to maintain the desired temperature with an accuracy of up to ± 0.05 °C.

Built-In Safety Features Protect Your Laser System

The system detects a lack of connection with a thermistor and then switches WARNING LED on. As long as the thermistor connection is lost, the driver will not take any action and the open collector output is grounded.

If the temperature is higher than 45 °C but below 70 °C, WARNING LED starts to blink but the driver is working normally. If the temperature is higher than 70 °C, WARNING LED is ON and the driver will not power the Peltier module. Also, the open collector output is grounded.

When measured temperature back to Tmin/Tmax range, the open connector output becomes disconnected and warning diode is OFF.
