The BELEKTRONIG built-in temperature controller is an integrable controller to control heating and Peltier elements. As an OEM component with a wide range of functionality, it is used in many professional laboratory and analytical instruments. The temperature control is performed by a PID algorithm in combination with a high-precision temperature measurement. The control output generates a PWM signal. An optional output filter to generate a DC output voltage is also available.

Additional Functions

In applications where further functions are required in addition to the high-precision temperature control, the potential of the BELEKTRONIG built-in temperature controllers is particularly beneficial. Thanks to extensive additional peripherals for connecting components such as analog sensors, LEDs or displays, additional requirements during device developments can be implemented in a versatlie way. Furthermore BELEKTRONIG also provides customer-specific adaptations on request.
